An amusement park is a park that features various attractions, such as rides and games, as well as other events for entertainment purposes. A theme park is a type of amusement park that bases its structures and attractions around a central theme, often featuring multiple areas with different themes. Unlike temporary and mobile funfairs and carnivals , amusement parks are stationary and built for long-lasting operation. They are more elaborate than city parks and playgrounds , usually providing attractions that cater to a variety of age groups. While amusement parks often contain themed areas, theme parks place a heavier focus with more intricately-designed themes that revolve around a particular subject or group of subjects.

125-562: Toy Story Midway Mania! (also known as Toy Story Mania! ) is an interactive 4-D theme park attraction, located at three Disney theme parks : Disney's Hollywood Studios at the Walt Disney World Resort , Disney California Adventure at the Disneyland Resort and Tokyo DisneySea at Tokyo Disney Resort . Designed by Walt Disney Imagineering and inspired by Disney · Pixar 's Toy Story franchise ,

250-403: A modular PLC – has a chassis (also called a rack ) that provides space for modules with different functions, such as power supply, processor, selection of I/O modules and communication interfaces – which all can be customized for the particular application. Several racks can be administered by a single processor and may have thousands of inputs and outputs. Either

375-557: A request for proposals for an electronic replacement for hard-wired relay systems based on a white paper written by engineer Edward R. Clark. The winning proposal came from Bedford Associates from Bedford, Massachusetts . The result, built in 1969, was the first PLC and designated the 084 , because it was Bedford Associates' eighty-fourth project. Bedford Associates started a company dedicated to developing, manufacturing, selling, and servicing this new product, which they named Modicon (standing for modular digital controller). One of

500-460: A token ). The cost of the attraction is often based on its complexity or popularity. For example, a guest might pay one ticket to ride a carousel but four tickets to ride a roller coaster . The park may allow guests to purchase a pass providing unlimited admissions to all attractions within the park for a specified duration of time. A wristband or pass is then shown at the attraction entrance to gain admission. Disneyland opened in 1955 using

625-530: A blaze of lights from the "White City." To make sure that the fair was a financial success, the planners included a dedicated amusement concessions area called the Midway Plaisance . Rides from this fair captured the imagination of the visitors and of amusement parks around the world, such as the first steel Ferris wheel , which was found in many other amusement areas, such as the Prater by 1896. Also,

750-455: A carnival atmosphere. In 1952, he created WED Enterprises to design the park, which was now to be built in Anaheim, and in 1953, was able to convince the bankers on funding the park with the help of a studio artist, Herb Ryman, by making an aerial drawing of Disneyland. By July 1954, construction had started with a deadline of one year. Disneyland opened on July 17, 1955, and two months after

875-461: A common element in multiple separate rungs. Unlike physical relays, there is usually no limit to the number of times an input, output or internal coil can be referenced in a PLC program. Some PLCs enforce a strict left-to-right, top-to-bottom execution order for evaluating the rung logic. This is different from electro-mechanical relay contacts, which, in a sufficiently complex circuit, may either pass current left-to-right or right-to-left, depending on

1000-565: A computer, with the PLC connected via a communication interface. A PLC works in a program scan cycle, where it executes its program repeatedly. The simplest scan cycle consists of 3 steps: The program follows the sequence of instructions. It typically takes a time span of tens of milliseconds for the processor to evaluate all the instructions and update the status of all outputs. If the system contains remote I/O—for example, an external rack with I/O modules—then that introduces additional uncertainty in

1125-665: A connected controller. The vulnerability was given a severity score of 10 out of 10 on the CVSS vulnerability scale . At the time of writing, the mitigation of the vulnerability was to limit network access to affected devices . Safety PLCs can be either a standalone device or a safety-rated hardware and functionality added to existing controller architectures ( Allen-Bradley GuardLogix, Siemens F-series, etc.). These differ from conventional PLC types by being suitable for safety-critical applications for which PLCs have traditionally been supplemented with hard-wired safety relays and areas of

1250-564: A general-purpose desktop computer to overlap some PLCs in certain applications. Desktop computer controllers have not been generally accepted in heavy industry because desktop computers run on less stable operating systems than PLCs, and because the desktop computer hardware is typically not designed to the same levels of tolerance to temperature, humidity, vibration, and longevity as the processors used in PLCs. Operating systems such as Windows do not lend themselves to deterministic logic execution, with

1375-453: A group of contacts controlling one coil is called a "rung" of a "ladder diagram", and this concept is also used to describe PLC logic. Some models of PLC limit the number of series and parallel instructions in one "rung" of logic. The output of each rung sets or clears a storage bit, which may be associated with a physical output address or which may be an "internal coil" with no physical connection. Such internal coils can be used, for example, as

1500-446: A pleasure ride of flying carriages that revolved around a central pylon. Other rides included the 'Grotto' (a fantasy ride), 'River Caves' (a scenic railway ), water chutes and a tobogganing tower. Fire was a constant threat in those days, as much of the construction within the amusement parks of the era was wooden. In 1911, Dreamland was the first Coney Island amusement park to completely burn down; in 1944, Luna Park also burned to

1625-460: A programming background. For this reason, a graphical programming language called Ladder Diagram (LD, LAD) was first developed. It resembles the schematic diagram of a system built with electromechanical relays and was adopted by many manufacturers and later standardized in the IEC 61131-3 control systems programming standard. As of 2015, it is still widely used, thanks to its simplicity. As of 2015,

1750-537: A programming device which is used to develop and later download the created program into the memory of the controller. Modern PLCs generally contain a real-time operating system , such as OS-9 or VxWorks . There are two types of mechanical design for PLC systems. A single box (also called a brick ) is a small programmable controller that fits all units and interfaces into one compact casing, although, typically, additional expansion modules for inputs and outputs are available. The second design type –

1875-469: A proper theme park. That same year, SeaWorld San Diego opened and displayed many varieties of aquatic and marine life. Initially meant to house Walt Disney's dream idea, EPCOT (Experimental Prototype Community Of Tomorrow), Disney executives decided to settle on building the park first in Walt Disney World and the city later. After six years of construction, Walt Disney World opened to

2000-406: A range of automation tasks. These are typically industrial processes in manufacturing where the cost of developing and maintaining the automation system is high relative to the total cost of the automation, and where changes to the system would be expected during its operational life. PLCs contain input and output devices compatible with industrial pilot devices and controls; little electrical design

2125-552: A second park or risk losing the land to the French government. The park opened March 16, 2002, with only three rides and California Adventure style theming. However, Hong Kong Disneyland was higher quality than the other black sheep, but still lacked the number of attractions that was needed, just like California Adventure and Walt Disney Studios Park. It opened on September 12, 2005, with only four lands, and had exorbitant wait times on opening day for everything from rides to food. In

2250-516: A simple PLC, or the PLC may have external I/O modules attached to a fieldbus or computer network that plugs into the PLC. The functionality of the PLC has evolved over the years to include sequential relay control, motion control, process control , distributed control systems , and networking . The data handling, storage, processing power, and communication capabilities of some modern PLCs are approximately equivalent to desktop computers . PLC-like programming combined with remote I/O hardware, allows

2375-412: A simple programming language focused on logic and switching operations, it was more user-friendly than computers using general-purpose programming languages . Early PLCs were programmed in ladder logic , which strongly resembled a schematic diagram of relay logic . It also permitted its operation to be monitored. In 1968, GM Hydramatic, the automatic transmission division of General Motors , issued

2500-442: A single manufacturer, different models may not be directly compatible. PLC programs are typically written in a programming device, which can take the form of a desktop console, special software on a personal computer , or a handheld programming device. Then, the program is downloaded to the PLC directly or over a network. It is stored either in non-volatile flash memory or battery-backed-up RAM . In some programmable controllers,

2625-674: A smaller roller coaster, the Joy Wheel, Miniature Railway, The Whip and the River Caves. A ballroom was constructed on the site of the Skating Rink in 1920 and in 1923 a Variety Cinema was built on the site. Between 1920 and 1935 over £500,000 was invested in the site, constantly adding new rides and facilities and culminating in the construction of the Dreamland Cinema complex in 1934 which stands to this day. Until 2011

2750-795: A source of fantasy and escape from real life. By the early 1900s, hundreds of amusement parks were operating in the United States and Canada. Trolley parks stood outside many cities. Parks like Atlanta's Ponce de Leon and Idora Park, near Youngstown, OH, took passengers to traditionally popular picnic grounds, which by the late 1890s also often included rides like the Giant Swing, Carousel , and Shoot-the-Chutes . These amusement parks were often based on nationally known parks or world's fairs : they had names like Coney Island , White City , Luna Park , or Dreamland . The American Gilded Age was, in fact, amusement parks' Golden Age that reigned until

2875-430: A special high-speed serial I/O link or comparable communication method is used so that racks can be distributed away from the processor, reducing the wiring costs for large plants. Discrete (digital) signals can only take on or off value (1 or 0, true or false ). Examples of devices providing a discrete signal include limit switches and photoelectric sensors . Analog signals can use voltage or current that

3000-467: A standalone attraction next to Disney World (especially now as Disney built one in Disney-MGM). So it divided up the segments of its California tour into individual attractions, such as Jaws , Disaster! , and Kongfrontation . Disney-MGM Studios opened it on May 1, 1989, with two major attractions: The Backlot Tour and The Great Movie Ride. The concept for the park started out as an EPCOT pavilion, but

3125-439: A unique address, and a PLC instruction can test if the input state is on or off. Just as a series of relay contacts perform a logical AND function, not allowing current to pass unless all the contacts are closed, so a series of "examine if on" instructions will energize its output storage bit if all the input bits are on. Similarly, a parallel set of instructions will perform a logical OR. In an electromechanical relay wiring diagram,

3250-464: A variety of ways, from the relay-derived ladder logic to programming languages such as specially adapted dialects of BASIC and C . While the fundamental concepts of PLC programming are common to all manufacturers, differences in I/O addressing, memory organization, and instruction sets mean that PLC programs are never perfectly interchangeable between different makers. Even within the same product line of

3375-481: Is a feature often found in PLC programming software. It allows for testing and debugging early in a project's development. Incorrectly programmed PLC can result in lost productivity and dangerous conditions. Testing the project in simulation improves its quality, increases the level of safety associated with equipment and can save costly downtime during the installation and commissioning of automated control applications since many scenarios can be tried and tested before

3500-718: Is an industrial computer that has been ruggedized and adapted for the control of manufacturing processes, such as assembly lines , machines, robotic devices, or any activity that requires high reliability, ease of programming, and process fault diagnosis. PLCs can range from small modular devices with tens of inputs and outputs (I/O) , in a housing integral with the processor, to large rack-mounted modular devices with thousands of I/O, and which are often networked to other PLC and SCADA systems. They can be designed for many arrangements of digital and analog I/O, extended temperature ranges, immunity to electrical noise , and resistance to vibration and impact. PLCs were first developed in

3625-501: Is analogous to the monitored variable and can take any value within their scale. Pressure, temperature, flow, and weight are often represented by analog signals. These are typically interpreted as integer values with various ranges of accuracy depending on the device and the number of bits available to store the data. For example, an analog 0 to 10 V or 4-20 mA current loop input would be converted into an integer value of 0 to 32,767. The PLC will take this value and translate it into

3750-491: Is becoming more commonplace in the PLC environment, connecting the previously separated plant floor networks and office networks. In February 2021, Rockwell Automation publicly disclosed a critical vulnerability affecting its Logix controllers family. The secret cryptographic key used to verify communication between the PLC and workstation could be extracted from the programming software (Studio 5000 Logix Designer) and used to remotely change program code and configuration of

3875-451: Is being referred to as both Toy Story Midway Mania! and Toy Story Mania! . While the attraction marquees and some in-park signage read the former, the latter has been used in press releases to the news media, used in both resorts' advertisements, and on the disneyland.com, disneyworld.com, and official promotional website for the attraction, along with attraction merchandise. Websites for both Disneyland and Walt Disney World both identified

4000-593: Is carried over various industrial network protocols, like Modbus , or EtherNet/IP . Many of these protocols are vendor specific. PLCs used in larger I/O systems may have peer-to-peer (P2P) communication between processors. This allows separate parts of a complex process to have individual control while allowing the subsystems to co-ordinate over the communication link. These communication links are also often used for user interface devices such as keypads or PC -type workstations. Formerly, some manufacturers offered dedicated communication modules as an add-on function where

4125-443: Is required, and the design problem centers on expressing the desired sequence of operations. PLC applications are typically highly customized systems, so the cost of a packaged PLC is low compared to the cost of a specific custom-built controller design. On the other hand, in the case of mass-produced goods, customized control systems are economical. This is due to the lower cost of the components, which can be optimally chosen instead of

4250-458: Is themed after stories based on the ocean and nautical adventure. It was constructed at a cost of ¥335 billion and opened on September 4, 2001. The park's two signature attractions are a modernized version of 20,000 Leagues Under The Sea and Journey To The Center of The Earth . In the early 90s, Michael Eisner wanted to make Disneyland in the image of Walt Disney World 's resort style. Plans were made for multiple hotels (such as one based on

4375-603: The Blackpool Pleasure Beach ranked among the top free of charge attractions in Britain. Blackpool Pleasure beach was developed continuously, requiring frequent large-scale investments. The construction of many new rides could be counted on. Rides included the Virginia Reel, Whip, Noah's Ark, Big Dipper and Dodgems. In the 1920s the "Casino Building" was built, which remains to this day. In 1923, land

4500-893: The Disneyland Resort and Universal Orlando Resort to thrilling coaster parks such as the Six Flags parks and Cedar Fair parks. Countless smaller ventures exist across the United States and around the world. Simpler theme parks directly aimed at smaller children have also emerged, such as Legoland . Examples of amusement parks in shopping malls exist in West Edmonton Mall , Pier 39 and Mall of America . Family fun parks starting as miniature golf courses have begun to grow to include batting cages, go-karts, bumper cars, bumper boats and water slides. Some of these parks have grown to include even roller coasters, and traditional amusement parks now also have these competition areas in addition to their thrill rides. In 2015, theme parks in

4625-649: The Grand Floridian Hotel ) and a new west coast version of EPCOT , called WESTCOT. WESTCOT never came to be due to local opposition from residents, rising costs, and the financial fallout of Disneyland Paris. After a corporate retreat in Colorado, Disney executives decided to make a park themed to California so that guests could experience all of California within the confines of the Disneyland Resort and would be built across from Disneyland on its 100-acre parking lot. Disney's California Adventure would be

4750-683: The SeaWorld and Busch Gardens parks also offer educational experiences, with each of the parks housing several thousand animals, fish and other sea life in dozens of attractions and exhibits focusing on animal education. Created in 1977, the Puy du Fou is a much-celebrated theme park in Vendée , France. It is centered around European, French and local history. It received several international prizes. Some theme parks did evolve from more traditional amusement park enterprises, such as Knott's Berry Farm . In

4875-563: The 1860s and 1870s created mechanical rides, such as the steam-powered carousel (built by Thomas Bradshaw, at the Aylsham Fair ), and its derivatives, notably from Frederick Savage of King's Lynn , Norfolk whose fairground machinery was exported all over the world; his "galloping horses" innovation is seen in carousels today. This inaugurated the era of the modern funfair ride, as the working classes were increasingly able to spend their surplus wages on entertainment. The second influence

5000-684: The 1870s along the Connecticut River . The trick was getting the public to the seaside or resort location. For Coney Island in Brooklyn, New York, on the Atlantic Ocean, a horse-drawn streetcar line brought pleasure seekers to the beach beginning in 1829. In 1875, a million passengers rode the Coney Island Railroad , and in 1876 two million visited Coney Island. Hotels and amusements were built to accommodate both

5125-478: The 1920s, Walter Knott and his family sold berries from a roadside stand, which grew to include a restaurant serving fried chicken dinners. Within a few years, lines outside the restaurant were often several hours long. To entertain the waiting crowds, Walter Knott built a Ghost Town in 1940, using buildings relocated from real old west towns such as the Calico, California , ghost town and Prescott, Arizona . In 1968,

5250-520: The California version officially opened on June 17, 2008. The Japan version of the attraction opened on July 9, 2012. Park guests wear 3-D glasses (Carnival Games Goggles) aboard spinning vehicles that travel through virtual environments based on classic carnival midway games. Ride vehicles seat up to eight in four back-to-back pairs. Small children are also able to ride on an adult's lap if they are facing forward with their legs securely underneath

5375-453: The Casino building to name a few. The Great Depression of the 1930s and World War II during the 1940s saw the decline of the amusement park industry. War caused the affluent urban population to move to the suburbs, television became a source of entertainment, and families went to amusement parks less often. By the 1950s, factors such as urban decay , crime , and even desegregation in

5500-528: The Dark Arts class with one shop and one restaurant in the former submarine lagoon at Magic Kingdom. She was also displeased with the lack of creative control she had and exited the deal. She went to Universal next and was also displeased with the initial plan to redress the Islands of Adventure's Lost Continent area. To remedy this, J.K Rowling wrestled creative control from Universal and forced them to make

5625-610: The European Middle Ages . An amusement park is a contemporary arrangement, designed to combine components of a fair, carnival, and theme park. An early example of an amusement park is the Bartholomew Fair . By the 18th and 19th centuries, they had evolved into places of entertainment for the masses, where the public could view freak shows , acrobatics , conjuring and juggling , take part in competitions and walk through menageries . A wave of innovation in

5750-538: The Golden Age of roller coasters, being the decade of frenetic building for these rides. In England, Dreamland Margate opened in 1880 with Frederick Savage's carousel the first amusement ride installed. In 1920 the Scenic Railway rollercoaster opened to the public with great success, carrying half a million passengers in its first year. The park also installed other rides common to the time including

5875-512: The Knott family fenced the farm, charged admission for the first time, and Knott's Berry Farm officially became a theme park. Because of its long history, Knott's Berry Farm currently claims to be "America's First Theme Park." Knott's Berry Farm is now owned by Cedar Fair Entertainment Company. Lake Compounce in Bristol, Connecticut, may be the true oldest continuously operating amusement park in

6000-560: The United States had a revenue of US$ 8 billion and theme parks in China had a revenue of US$ 4.6 billion , with China expected to overtake the United States by 2020. Some parks use rides and attractions for educational purposes. There are also Holy Land USA and the Holy Land Experience , which are theme parks built to inspire Christian piety. Dinosaur World entertains families with dinosaurs in natural settings, while

6125-534: The United States, open since 1846. Santa Claus Town, which opened in Santa Claus, Indiana , in 1935 and included Santa's Candy Castle and other Santa Claus-themed attractions is considered the first themed attraction in the United States: a precursor to the modern day theme park. Santa Claus Land (renamed Holiday World in 1984) opened in 1946 in Santa Claus, Indiana , and many people will argue that it

6250-645: The attraction was first unveiled during a press conference at Walt Disney World in January 2007. The Florida version was officially opened by Tim Allen on May 31, 2008, on the same date that the Buzz Lightyear action figure launched onboard Space Shuttle flight STS-124 (whose objective was to deliver the largest module of the space station - Kibō , the Japanese Experiment Module pressurized section, developed by JAXA ), while

6375-487: The attraction with the registered trademark "Toy Story Midway Mania!" as of September 2014. As of February 2019, the attraction is known as "Toy Story Mania!", except for the Disney California Adventure version which is still known as “Toy Story Midway Mania!” Music for the queue area was arranged and recorded by Jennifer Hammond at Capitol Studios with a live orchestra. More than an hour of music

6500-661: The attraction's different games. Similar technology had been used in Disney attractions such as Pirates of the Caribbean: Battle for Buccaneer Gold at DisneyQuest and several Buzz Lightyear attractions . According to Disney, it is the first attraction created simultaneously by Walt Disney Imagineering for two theme parks. The line at both parks features a large Mr. Potato Head Audio-Animatronic figure that interacts with guests through pre-recorded snippets of dialogue performed by late comedian Don Rickles , who voiced

6625-642: The automobile manufacturing industry to provide flexible, rugged and easily programmable controllers to replace hard-wired relay logic systems. Dick Morley , who invented the first PLC, the Modicon 084, for General Motors in 1968, is considered the father of PLC. A PLC is an example of a hard real-time system since output results must be produced in response to input conditions within a limited time, otherwise unintended operation may result. Programs to control machine operation are typically stored in battery-backed-up or non-volatile memory . The PLC originated in

6750-542: The beginnings of the Wurstelprater as an amusement park. The concept of a fixed park for amusement was further developed with the beginning of the world's fairs . The first World fair began in 1851 with the construction of the landmark Crystal Palace in London, England. The purpose of the exposition was to celebrate the industrial achievement of the nations of the world and it was designed to educate and entertain

6875-718: The boardwalk out over the ocean. The first of several was the Ocean Pier in 1891, followed later by the Steel Pier in 1898, both of which boasted rides and attractions typical of that time, such as Midway-style games and electric trolley rides. The boardwalk also had the first Roundabout installed in 1892 by William Somers, a wooden predecessor to the Ferris Wheel . Somers installed two others in Asbury Park , New Jersey and Coney Island , New York. Another early park

7000-481: The character in the Toy Story films. The sophisticated figure identifies people in the audience, sings and tells jokes. Only five mini-games can be used at a time. So far, only one game has left the attraction. On May 21, 2010, the original dart throwing game, Bo Peep's Baaa-loon Pop, was replaced with "Rex and Trixie's Dino Darts" (updated with the release of Toy Story 3 ). At its debut, Toy Story Midway Mania!

7125-669: The configuration of surrounding contacts. The elimination of these "sneak paths" is either a bug or a feature, depending on the programming style. More advanced instructions of the PLC may be implemented as functional blocks, which carry out some operation when enabled by a logical input and which produce outputs to signal, for example, completion or errors, while manipulating variables internally that may not correspond to discrete logic. PLCs use built-in ports, such as USB , Ethernet , RS-232 , RS-485 , or RS-422 to communicate with external devices (sensors, actuators) and systems ( programming software , SCADA , user interface ). Communication

7250-569: The control system can command the affected game screens to launch a non-scoring practice round, so that guests may continue to shoot targets while they wait. Similarly, it can instruct the show control system to play an audio spiel telling guests about the delay. As the games are software-based, changes can be made to the attraction's lineup of games without significant effort. In April 2010, Disney Parks announced plans to replace Bo Peep's Baaa-loon Pop with Rex and Trixie's Dino Darts. The change took place on May 21, 2010. The new game includes one of

7375-410: The desired units of the process so the operator or program can read it. Some special processes need to work permanently with minimum unwanted downtime. Therefore, it is necessary to design a system that is fault-tolerant and capable of handling the process with faulty modules. In such cases to increase the system availability in the event of hardware component failure, redundant CPU or I/O modules with

7500-536: The discovery of the Stuxnet computer worm in June 2010, the security of PLCs received little attention. Modern programmable controllers generally contain real-time operating systems, which can be vulnerable to exploits in a similar way as desktop operating systems, like Microsoft Windows . PLCs can also be attacked by gaining control of a computer they communicate with. Since 2011, these concerns have grown – networking

7625-417: The documentation. Troubleshooting was a tedious process. When general-purpose computers became available, they were soon applied to control logic in industrial processes. These early computers were unreliable and required specialist programmers and strict control of working conditions, such as temperature, cleanliness, and power quality. The PLC provided several advantages over earlier automation systems. It

7750-534: The early 2000s, the Harry Potter book series written by J.K Rowling had become a pop culture phenomenon. Universal and Disney entered a bidding war over the theme park rights to the books, but Disney seemed to have won after Rowling signed a letter of intent with Disney. However, Rowling was disappointed with Disney's small-scale plans to install an omnimover attraction themed to the Defense Against

7875-413: The early 90s after the opening of Universal Studios Florida, Universal sought to build a second theme park, one aimed more towards children and their families. Universal acquired the theme park rights to many properties including Marvel and Dr. Seuss to build the park around. In 1999, Universal Studios opened Universal Studios Islands of Adventure under the new resort name Universal Studios Escape. The park

8000-545: The elements of PLC programs as graphic symbols, but plain ASCII character representations of contacts, coils, and wires were common. Programs were stored on cassette tape cartridges . Facilities for printing and documentation were minimal due to a lack of memory capacity. The oldest PLCs used magnetic-core memory . A PLC is an industrial microprocessor-based controller with programmable memory used to store program instructions and various functions. It consists of: PLCs require

8125-643: The emergence of the amusement park industry. Bakken ("The Hill") in Klampenborg , Denmark, Wurstelprater in Vienna, Austria, and Tivoli Gardens in Copenhagen, Denmark are the three oldest operating amusement parks in the world. Lake Compounce opened in 1846 and is considered the oldest, continuously operating amusement park in North America. The amusement park evolved from traditions in

8250-644: The end of June, but Jaws had to be rebuilt and reopened three years later. However, Universal learned from opening day and started conducting exit surveys and special ticket deals. In 1992, Disney opened its first European park, Euro Disneyland , outside of Paris, France, designed to be like the Magic Kingdom in Florida, yet it caters to the European tastes through changes, including removing Tomorrowland and replacing it with Discoveryland , themed to

8375-619: The experience of the enclosed ideal city with wonder, rides, culture and progress (electricity), was based on the creation of an illusory place. The " midway " introduced at the Columbian Exposition would become a standard part of most amusement parks, fairs, carnivals, and circuses. The midway contained not only the rides, but other concessions and entertainments such as shooting galleries , penny arcades , games of chance , and shows. Many modern amusement parks evolved from earlier pleasure resorts that had become popular with

8500-475: The first 084 models built is now on display at Schneider Electric's facility in North Andover, Massachusetts . It was presented to Modicon by GM , when the unit was retired after nearly twenty years of uninterrupted service. Modicon used the 84 moniker at the end of its product range until after the 984 made its appearance. In a parallel development, Odo Josef Struger is sometimes known as the "father of

8625-441: The game screens, two tracking systems provide the game control system with the vehicle's exact location, making sure that gameplay is not affected by even minor differences in vehicle position. According to Jody Gerstner, executive director of show and ride controls, "The game doesn’t care if the car parks in the same spot every time. It just needs to know where each car has actually parked, and it can compensate." Additional sensors in

8750-410: The gardens were originally designed for the elites, they soon became places of great social diversity. Public firework displays were put on at Marylebone Gardens , and Cremorne Gardens offered music, dancing, and animal acrobatics displays. Prater in Vienna, Austria, began as a royal hunting ground which was opened in 1766 for public enjoyment. There followed coffee-houses and cafés, which led to

8875-634: The ghettos led to changing patterns in how people chose to spend their free time. Many of the older, traditional amusement parks closed or burned to the ground. Many would be taken out by the wrecking ball to make way for suburb and housing and development . In 1964, Steeplechase Park , once the king of all amusement parks, closed down for good. The traditional amusement parks which survived, for example, Kennywood , in West Mifflin, Pennsylvania , and Cedar Point , in Sandusky, Ohio , did so in spite of

9000-431: The great futuristic thinkers of European culture such as H. G. Wells and Jules Verne . A recession in the French economy and the immense public backlash against the park led to financial hardship, putting the park into debt. However, this did not stop Disney from expanding Disney-MGM Studios with The Twilight Zone Tower of Terror , in 1994, and building their fourth Walt Disney World park, Disney's Animal Kingdom . In

9125-516: The ground. Most of Ingersoll's Luna Parks were similarly destroyed, usually by arson , before his death in 1927. During the Gilded Age , many Americans began working fewer hours and had more disposable income. With new-found money and time to spend on leisure activities, Americans sought new venues for entertainment. Amusement parks, set up outside major cities and in rural areas, emerged to meet this new economic opportunity. These parks served as

9250-553: The land a full scale, realistic re-creation of Hogsmeade and Hogwarts without being a refurbishment of an existing area. The project was announced in 2007 and in 2010 the land was opened to the public and made Universal Orlando a must visit destination. Today, there are over 475 amusement parks in the United States, ranging from mega-parks and those that are operated by Warner Bros., Disney , Six Flags and NBCUniversal . The amusement park industry's offerings range from immersive theme parks such as Warner Bros. World Abu Dhabi ,

9375-519: The larger, more popular rides. Later, the "D-ticket" was added, then finally the " E-ticket ", which was used on the biggest and most elaborate rides, like Space Mountain . Smaller tickets could be traded up for use on larger rides so that for example two or three A-tickets would equal a single B-ticket. Disneyland, as well as the Magic Kingdom at Walt Disney World, abandoned this practice in 1982. Programmable logic controller A programmable logic controller ( PLC ) or programmable controller

9500-408: The largest disaster Disney ever created because unlike Disneyland, it would be set in the modern day and spoof modern-day California with its cheap, insincere, and flat backdrops. The park would be adult focused, sell fine food, and serve alcohol. When the park opened on February 8, 2001, it received a chilly reception for its lack of attractions, poor environment (for example, Hollywood Studios Backlot

9625-462: The late 1920s. The Golden Age of amusement parks also included the advent of the kiddie park. Founded in 1925, the original Kiddie Park is located in San Antonio, Texas , and is still in operation as of 2022 . The kiddie parks became popular all over America after World War II. This era saw the development of new innovations in roller coasters that included extreme drops and speeds to thrill

9750-468: The late 1960s in the automotive industry in the US and was designed to replace relay logic systems. Before, control logic for manufacturing was mainly composed of relays , cam timers , drum sequencers , and dedicated closed-loop controllers . The hard-wired nature of these components made it difficult for design engineers to alter the automation process. Changes would require rewiring and careful updating of

9875-487: The logic in a predictable and repeating sequence, and ladder logic allows the person writing the logic to see any issues with the timing of the logic sequence more easily than would be possible in other formats. Up to the mid-1990s, PLCs were programmed using proprietary programming panels or special-purpose programming terminals , which often had dedicated function keys representing the various logical elements of PLC programs. Some proprietary programming terminals displayed

10000-431: The logic, and so it was instead represented as a series of logic expressions in some kind of Boolean format, similar to Boolean algebra . As programming terminals evolved, because ladder logic was a familiar format used for electro-mechanical control panels, it became more commonly used. Newer formats, such as state logic, function block diagrams , and structured text exist. Ladder logic remains popular because PLCs solve

10125-406: The majority of PLC systems adhere to the IEC 61131-3 standard that defines 2 textual programming languages: Structured Text (ST; similar to Pascal ) and Instruction List (IL); as well as 3 graphical languages: ladder logic , function block diagram and sequential function chart . Instruction List (IL) was deprecated in the third edition of the standard. Modern PLCs can be programmed in

10250-665: The memory dedicated to the safety instructions. The standard of safety level is the SIL . A safety PLC might be used to control access to a robot cell with trapped-key access , or to manage the shutdown response to an emergency stop button on a conveyor production line. Such PLCs typically have a restricted regular instruction set augmented with safety-specific instructions designed to interface with emergency stop buttons, light screens, and other safety-related devices. The flexibility that such systems offer has resulted in rapid growth of demand for these controllers. PLCs are well adapted to

10375-471: The modern, competitive amusement park industry. In the late 1950s, Wynne visited Disneyland and was inspired to create an affordable, closer, and larger amusement park that would be filled with fantasy. He followed in the steps of Disney and had subdivisions within the park that reflected different lands. The subdivisions included the Old South and other sections that referenced Wynne's background. By 1968,

10500-466: The motivation for entrepreneurs to build accommodation and create new attractions, leading to more visitors and a rapid cycle of growth throughout the 1850s and 1860s. In 1879, large parts of the promenade at Blackpool were wired. The lighting and its accompanying pageants reinforced Blackpool's status as the North of England's most prominent holiday resort, and its specifically working class character. It

10625-758: The new characters from the Toy Story 3 feature film, which was released in June 2010. In October 2014, Disney's Hollywood Studios began testing a new procedure that would require all riders to have FastPass reservations for the attraction. The test, scheduled to last only a few days, eliminated the standby line that is used by visitors who have not already obtained a FastPass ticket for the ride, either because they had all been claimed or they were holding FastPasses for other attractions. Some analysts suggest that this process could become more common in years to come as amusement parks attempt to keep guests from getting frustrated or waiting in extremely long lines. The attraction

10750-482: The odds. Inspired by the layout of Tivoli Gardens theme park in Copenhagen, Denmark, in 1951, Walt Disney came up with the idea of having an amusement park next to the studios in Burbank. The park would have been called Mickey Mouse Park , built across the street with a western area featuring a steam driven paddleboat, a turn of the century town, and a midway. It was rejected by the Burbank city council in fear of

10875-438: The original levels & Infini-D technology (Infini-D glasses are included). A version for Xbox 360 and PlayStation 3 was released on October 30, 2012, and developed by High Voltage Software . Theme park Amusement parks evolved from European fairs , pleasure gardens , and large picnic areas , which were created for people's recreation . World's fairs and other types of international expositions also influenced

11000-466: The park opened, it welcomed its one millionth guest. Because of the financial success of Disneyland, the amusement industry was reinvigorated. What became Busch Gardens Tampa opened in 1959 as a garden and bird sanctuary. Six Flags Over Texas opened in 1961, themed to the six different countries that ruled over Texas. In 1964, Universal Studios Hollywood opened to the public with a studio tour of their backlot that had multiple adventure scenes and became

11125-591: The park. In 1897, Sea Lion Park was joined by Steeplechase Park , the first of three major amusement parks that would open in the Coney Island area. George Tilyou designed the park to provide thrills and entertainment. The combination of the nearby population center of New York City and the ease of access to the area made Coney Island the embodiment of the American amusement park. Coney Island also featured Luna Park (1903) and Dreamland (1904). Coney Island

11250-426: The park. Other revenue sources include parking fees, food and beverage sales and souvenirs. Practically all amusement parks operate using one of two admission principles: In amusement parks using the pay-as-you-go scheme, a guest enters the park at little or no charge. The guest must then purchase rides individually, either at the attraction's entrance or by purchasing ride tickets (or a similar exchange method, like

11375-503: The pay-as-you-go format. Initially, guests paid the ride admission fees at the attractions. Within a short time, the problems of handling such large amounts of coins led to the development of a ticket system that, while now out of use, is still part of the amusement-park lexicon. In this new format, guests purchased ticket books that contained a number of tickets, labeled "A", "B" and "C." Rides and attractions using an "A-ticket" were generally simple, with "B-tickets" and "C-tickets" used for

11500-437: The people who worked on that project was Dick Morley , who is considered to be the father of the PLC. The Modicon brand was sold in 1977 to Gould Electronics and later to Schneider Electric , its current owner. About this same time, Modicon created Modbus , a data communications protocol used with its PLCs. Modbus has since become a standard open protocol commonly used to connect many industrial electrical devices. One of

11625-530: The processor had no network connection built-in. PLCs may need to interact with people for the purpose of configuration, alarm reporting, or everyday control. A human-machine interface (HMI) is employed for this purpose. HMIs are also referred to as man-machine interfaces (MMIs) and graphical user interfaces (GUIs). A simple system may use buttons and lights to interact with the user. Text displays are available as well as graphical touch screens. More complex systems use programming and monitoring software installed on

11750-421: The program is transferred from a personal computer to the PLC through a programming board that writes the program into a removable chip, such as EPROM . Manufacturers develop programming software for their controllers. In addition to being able to program PLCs in multiple languages, they provide common features like hardware diagnostics and maintenance, software debugging, and offline simulation. PLC simulation

11875-563: The programmable logic controller" as well. He was involved in the invention of the Allen-Bradley programmable logic controller and is credited with coining the PLC acronym. Allen-Bradley (now a brand owned by Rockwell Automation ) became a major PLC manufacturer in the United States during his tenure. Struger played a leadership role in developing IEC 61131-3 PLC programming language standards. Many early PLC programming applications were not capable of graphical representation of

12000-556: The public for day-trips or weekend holidays, for example, seaside areas such as Blackpool , United Kingdom and Coney Island , United States. In the United States, some amusement parks grew from picnic groves established along rivers and lakes that provided bathing and water sports, such as Lake Compounce in Connecticut, first established as a picturesque picnic park in 1846, and Riverside Park in Massachusetts, founded in

12125-456: The public on October 1, 1971. Meant to be a larger east coast version of Disneyland, it had copies of most of the attractions from Disneyland (except for Liberty Square and the Hall of Presidents ), yet it was financially the most ambitious project Walt Disney Productions had ever undertaken, and succeeded once the holiday crowds came in during Thanksgiving. In 1982, Walt Disney Productions opened

12250-448: The response time of the PLC system. As PLCs became more advanced, methods were developed to change the sequence of ladder execution, and subroutines were implemented. Special-purpose I/O modules may be used where the scan time of the PLC is too long to allow predictable performance. Precision timing modules, or counter modules for use with shaft encoders , are used where the scan time would be too long to reliably count pulses or detect

12375-453: The result that the controller may not always respond to changes of input status with the consistency in timing expected from PLCs. Desktop logic applications find use in less critical situations, such as laboratory automation and use in small facilities where the application is less demanding and critical. The most basic function of a programmable logic controller is to emulate the functions of electromechanical relays. Discrete inputs are given

12500-474: The riders. By the end of the First World War, people seemed to want an even more exciting entertainment, a need met by roller coasters. Although the development of the automobile provided people with more options for satisfying their entertainment needs, the amusement parks after the war continued to be successful, while urban amusement parks saw declining attendance. The 1920s is more properly known as

12625-557: The safety bar. The attraction features five mini-games after a practice round, where the player can hit targets from 100 to 5,000 points. Each mini game includes at least one " Easter egg " that can trigger additional targets or gameplay changes. In order, the games are: Each guest's score is recorded by an onboard display screen as points are acquired with individual toy cannons firing simulated projectiles at virtual targets. Toy Story characters including Woody , Hamm , Buzz Lightyear , Rex , Trixie and many more characters appear during

12750-449: The same functionality can be added to hardware configuration for preventing total or partial process shutdown due to hardware failure. Other redundancy scenarios could be related to safety-critical processes, for example, large hydraulic presses could require that both PLCs turn on output before the press can come down in case one output does not turn off properly. Programmable logic controllers are intended to be used by engineers without

12875-850: The second Six Flags park, Six Flags Over Georgia , opened, and in 1971, Six Flags Over Mid-America (now Six Flags St. Louis ) opened near St. Louis , Missouri. Also in 1971 was the opening of the Walt Disney World resort complex in Florida . In 1991 Warner Bros. in partnership with Village Roadshow, opened their own Warner Bros. Movie World . It is the only Movie-Related theme park in Australia. Warner Bros. continued their theme park ventures and opened Warner Bros. World Abu Dhabi in UAE and Parque Warner Madrid in Spain. Amusement parks collect much of their revenue from admission fees paid by guests attending

13000-535: The second Walt Disney World park, EPCOT Center, based on Walt Disney's futurist ideals and World Fairs. Like a World's Fair, the park would display the latest technologies in an area called Future World, and the cultural pavilions in World Showcase. In 1987, Disney announced that it would open its third Disney World park, Disney-MGM Studios in 1989, which would have a working backlot. However, Universal knew that its Californian backlot tour would not work as

13125-598: The sense of rotation of an encoder. This allows even a relatively slow PLC to still interpret the counted values to control a machine, as the accumulation of pulses is done by a dedicated module that is unaffected by the speed of program execution. In his book from 1998, E. A. Parr pointed out that even though most programmable controllers require physical keys and passwords, the lack of strict access control and version control systems, as well as an easy-to-understand programming language make it likely that unauthorized changes to programs will happen and remain unnoticed. Prior to

13250-577: The sites, expanding them from picnic groves to include regular entertainments, mechanical amusements, dance halls, sports fields, boat rides, restaurants and other resort facilities. Some of these parks were developed in resort locations, such as bathing resorts at the seaside in New Jersey and New York . A premiere example in New Jersey was Atlantic City , a famous vacation resort. Entrepreneurs erected amusement parks on piers that extended from

13375-428: The spring-action shooter provide information on its orientation, which is fine-tuned using data on the position of the ride vehicle at the screen and the rotation of the seats on the vehicle base. All three sub-systems work together to handle any contingency. For example, if a delay or other vehicle stoppage is detected (such as might occur if the loading and unloading of the ride vehicles is taking longer than expected),

13500-743: The system is activated. The main difference from most other computing devices is that PLCs are intended for and therefore tolerant of more severe conditions (such as dust, moisture, heat, cold), while offering extensive input/output (I/O) to connect the PLC to sensors and actuators . PLC input can include simple digital elements such as limit switches , analog variables from process sensors (such as temperature and pressure), and more complex data such as that from positioning or machine vision systems. PLC output can include elements such as indicator lamps, sirens, electric motors , pneumatic or hydraulic cylinders, magnetic relays , solenoids , or analog outputs. The input/output arrangements may be built into

13625-551: The theme park, Silver Dollar City . The park is still owned and operated by the Herschends and the family has several other parks including Dollywood , Kentucky Kingdom and Wild Adventures . The first regional amusement park, as well as the first Six Flags park, Six Flags Over Texas was officially opened in 1961 in Arlington, Texas . The first Six Flags amusement park was the vision of Angus Wynne Jr. and helped create

13750-527: The upper classes and the working class at the beach. The first carousel was installed in the 1870s, the first roller coaster , the " Switchback Railway ", in 1884. In England, Blackpool was a popular beachside location beginning in the 1700s. It rose to prominence as a seaside resort with the completion in 1846 of a branch line to Blackpool from Poulton on the main Preston and Wyre Joint Railway line. A sudden influx of visitors, arriving by rail, provided

13875-427: The vehicles using a hard-wired network within the track. The one-way communications flow adds a factor of safety, even though the wireless network is protected against outside interference, such as a denial-of-service attack . The attraction features more than 150 PCs , which includes one HP Windows XP PC for each of Midway Mania's 56 game screens, as well as others that control the special effects at each game. At

14000-481: The visitors. American cities and businesses also saw the world's fair as a way of demonstrating economic and industrial success. The World's Columbian Exposition of 1893 in Chicago , Illinois was an early precursor to the modern amusement park. The fair was an enclosed site, that merged entertainment, engineering and education to entertain the masses. It set out to bedazzle the visitors, and successfully did so with

14125-575: Was a huge success and by the year 1910 attendance on days could reach a million people. Fueled by the efforts of Frederick Ingersoll who borrowed the name, other " Luna Parks " were quickly erected worldwide and opened to rave reviews. The first amusement park in England was opened in 1896 – the Blackpool Pleasure Beach by W. G. Bean. In 1904, Sir Hiram Maxim 's Captive Flying Machine was introduced; he had designed an early aircraft powered by steam engines that had been unsuccessful and instead opened up

14250-560: Was allegedly designed by former Disney Imagineers who left after the financial disaster of Disneyland Paris. In the late 80s, the Oriental Land Company (the owners and operators of Tokyo Disneyland resort which opened in 1983) wanted a second park. None of the current non-Magic Kingdom parks satisfied the Japanese, but one concept thrown away for Disneyland's second gate inspired a new one: DisneySea . Tokyo DisneySea

14375-473: Was designed to tolerate the industrial environment better than systems intended for office use, and was more reliable, compact, and required less maintenance than relay systems. It was easily expandable with additional I/O modules. While relay systems required tedious and sometimes complicated hardware changes in case of reconfiguration, a PLC can be reconfigured by loading new or modified code. This allowed for easier iteration over manufacturing process design. With

14500-440: Was one of the most technologically sophisticated attractions yet developed by Walt Disney Imagineering, costing an estimated $ 80 million to design and build. It marked the company's first use of industrial Ethernet for a ride's control system. Many of the parts for the attraction's control system came from two of Disney's corporate sponsors, Siemens AG (from Spaceship Earth ) and Hewlett-Packard (from Mission: Space ). The ride

14625-500: Was reclaimed from the sea front. It was at this period that the park moved to its 44-acre (18 ha) current location above what became Watson Road, which was built under the Pleasure Beach in 1932. During this time Joseph Emberton, an architect famous for his work in the amusement trade was brought in to redesign the architectural style of the Pleasure Beach rides, working on the "Grand National" roller coaster, "Noah's Ark" and

14750-650: Was recorded, all based on the first two Toy Story scores composed by Randy Newman . It went on to be featured at Toy Story Lands across the globe. Disney Interactive Studios released a Toy Story Mania! video game in September 2009 exclusively for the Nintendo Wii console. The game features gameplay and levels similar to those in the theme park attractions, along with original levels and features. Jakks Pacific also released their "Plug It In & Play TV Game" version of Toy Story Mania! in 2010 featuring

14875-567: Was the Eldorado Amusement Park that opened in 1891 on the banks of the Hudson River , overlooking New York City . It consisted of 25 acres. The first permanent enclosed entertainment area, regulated by a single company, was founded in Coney Island in 1895: Sea Lion Park at Coney Island in Brooklyn. This park was one of the first to charge admission fee to get into the park in addition to sell tickets for rides within

15000-686: Was the pleasure garden . An example of this is the world's oldest amusement park, Bakken ("The Hill"), which opened in mainland Europe in 1583. It is located north of Copenhagen in Klampenborg, Denmark . Another early garden was the Vauxhall Gardens , founded in 1661 in London. By the late 18th century, the site had an admission fee for its many attractions. It regularly drew enormous crowds, with its paths often noted for romantic assignations; tightrope walkers, hot air balloon ascents, concerts and fireworks providing amusement. Although

15125-473: Was the biggest system that had been built at the time and ran on one of Disney's most advanced automation systems to date. The control system is divided into three components: one for the ride vehicles, one for the games and one more for the attraction's special effects. Programmable logic controllers in the vehicles alert the control system wirelessly via ProfiNET RT to the vehicle's speed and location. The central controller then sends its instructions back to

15250-479: Was the first true Theme Park despite Knott's history. In the 1950s the Herschend family took over operation of the tourist attraction, Marvel Cave near Branson, Missouri . Over the next decade they modernized the cave, which led to large numbers of people waiting to take the tour. The Herschend family opened a recreation of the old mining town that once existed atop Marvel Cave. The small village eventually became

15375-645: Was the forerunner of the present-day Blackpool Illuminations . By the 1890s, the town had a population of 35,000, and could accommodate 250,000 holidaymakers. The number of annual visitors, many staying for a week, was estimated at three million. In the final decade of the 19th century, electric trolley lines were developed in many large American cities. Companies that established the trolley lines also developed trolley parks as destinations of these lines. Trolley parks such as Atlanta 's Ponce de Leon Park , or Reading's Carsonia Park were initially popular natural leisure spots before local streetcar companies purchased

15500-493: Was themed to a modern-day movie backlot of modern-day Hollywood), and overemphasis on retail and dining. When John Hench (an original Imagineer who worked with Walt and was a chief creative executive at Imagineering since Imagineering was founded) was asked for his opinion on the park, he reportedly said, "I preferred the parking lot." Walt Disney Studios Park in Paris was the second Disneyland Paris park. Disney had to build

15625-610: Was turned into a park as a "half day" attraction—a complement to the rest of the resort. The rest of the park was themed to 1930s Hollywood and featured lost parts of Hollywood like the Brown Derby. Universal Studios Florida opened on June 7, 1990 (delayed by one year) to great fanfare, but the primary attractions were experiencing severe technical difficulties. All three of the park's major attractions (Jaws, Disaster!, and Kongfrontation) were not working and suffered major technical difficulties. Disaster! and Kongfrontation were fixed by
