Now many DCS companies have multiple DCS systems

Honeywell has TPS and PKS: The early DCS systems were the TDC3000 system; based on this, Honeywell developed its own TPS system. In collaboration with AB, it created Planscape, and after the partnership ended, it continued to upgrade to PKS.

Could everyone be more specific? There are many beginners here, and everyone has different understandings. For example, Siemens seems to use only PCS-7; its controllers are of the S7-400 type, with I/O units of the 300 series, and it uses its own software to create its own PCS7 DCS system.:lol

Could you be more detailed? I only know about the CS3000 :)

It’s possible to connect them together using OPC; I’ve used SCAP as well

I’m a beginner and am learning Honeywell’s PKS

1. Honeywell has a large and complex number of systems, but integration has improved significantly in recent years. The classic systems are mainly TDC2000 --》 TDC3000 --》 TPS. The new-style system is PlantScape --》 E-PKS R1XX --》 E-PKS R2XX --》 E-PKS R3XX. In the future, it is likely that all systems will need to be integrated and unified on PKS R3XX. 2. ABB’s systems are the most complicated and chaotic. ABB-Bailey, which specializes in main control systems for power plants, promotes the Symphony Harmony system. Hartman & Brown in Germany, acquired by Bailey, offers the AC800F system in its lower-end range, while its higher-end models are the AC870P; the AC870P is an upgraded version of the classic Melody series. . . It seems that in China, only Chuanyi is developing this system, and they don’t do a good job at it – the main issue is the cost. . . Melody is not about a disturbance-free lower garment or anything of the sort; Melody represents a plug-and-play concept. Super awesome. . . It could be nearly wiped out. The AC800M is currently the most popular system, primarily promoted by the headquarters in Sweden. It is used to replace all other current systems. Although the AC450 has been discontinued, many existing users are still using it in new projects. Although the AC800PEC is 10-15 times more expensive than conventional DCS, some people still use it. It’s still being sold. Sales are pretty good. The newly developed AC700F also calls itself Micro DCS. I don’t know how to locate it.

I think different DCS manufacturers have different DCS systems, mainly tailored for various industries. For example: Emerson has DeltaV and Ovation. The DeltaV system is primarily designed for the petrochemical industry, while Ovation is mainly used in the power sector.

Actually, Ovation comes from XiU; it is the result of a partnership. Emerson has great ambitions in the field of electricity

In addition to independent development, many manufacturers’ multiple DCS systems stem from historical acquisitions. For example, the ABB Mod300——AC460 series is based on the Mod300 product acquired from Taloy, with an attempt to integrate it into the OCS product line. . . OCS includes AC410, 450, 460. Net90 --》 Info90--》Info90 Open --》 Symphony; the latter group acquired Bailey’s product line. ABB-Bailey has been focusing on developing main control systems for large power units. The FreeLance family and the Melody family mainly acquired the product lines of German company Harman & Brown. At that time, it had not been long since Bailey acquired H&B, when ABB acquired Bailey outright; as a result, H&B also came under ABB’s umbrella, falling under Freelance2000 --》 FieldControl --》 AC800F. Among them, FieldControl had a short lifespan, but it enabled a successful transition from FL2000 to AC800F. The high-end model in the H&B series is Melody, and its upgraded version is the AC870P. There seem to be others; several systems were acquired as well, but I can no longer remember them. So, for now, the DCS systems of ABB have the most factions, the most varied styles, and the greatest chaos.

Emerson’s route is much simpler. 1. Delta V focuses on the petrochemical industry, with its versions continuously being upgraded. There are hardly any major changes in the hardware; in particular, the IO cards are still supplied by MTL OEM. Both the FF cards and CPUs are manufactured in-house. 2. Ovation is the system that was acquired after Westinghouse, having evolved from WDPF.

Emerson’s early FF cards were also integrated NI FF communication cards, manufactured by MTL OEM. The current FF card modules are developed by them themselves. Ovation later introduced FF gateway devices, changed the H1 Card housings in the DeltaV system to white, and integrated them. This post was last edited by flyfish on 2009-2-19 11:49.]

It seems that Yokogawa and Siemens are quite honest companies, with their own set of standards for self-inspection.

I’ve used Xinhua’s DCS – it was very good. It’s a shame it was acquired by GE, but Xinhua itself still develops some products using that technology. When I think of this brand, I feel both emotional and sad. It reminds me of the saying \"Raising a son is like raising a pig to be sold.\" Fortunately, their new systems are still quite usable; it’s just that the market for them is too small.

Siemens is a century-old giant that grew during World War I and World War II; the notorious **Nazi Party was established in Siemens’ factories. Siemens began producing relays in 1958, and later made PLCs its main product ； Its first PLC was developed 4 years after MODICAN. In 1991, it surprised the Americans by acquiring TI’s PLC business; this move was aimed at removing barriers to entering the U.S. market. Subsequently, it acquired AAI, Moore, and Milltronics companies, with the acquisition of Moore being intended to enter the DCS market for process control ； It then acquired Turbo, AO, ORSI, and A*va companies; some of these acquisitions were made out of friendship, while others were intended to expand the product portfolio. In May 2003, Compex was acquired, which was Danfoss Flow’s flow control division; this move clearly demonstrated the intention to enter the market for automated instrumentation. In 2005, Siemens acquired the American medium-voltage frequency conversion manufacturer ROBICON, strengthening Siemens’ position in the field of industrial drives. In January 2006, Siemens acquired the American company Berwanger, which specialized in front-end engineering design as well as plant system integration and software services, in an effort to strengthen its position in the U.S. oil and gas sector ； It then acquired the 40-year-old American company Controlotron, which specializes in gas flow measurement, and subsequently acquired the German company Opto-Control, which is involved in automated optical inspection. At the end of 2006, Siemens acquired FLENDER Holding GmbH, one of the world’s largest suppliers of gear reducer systems, in order to expand its business in the field of industrial drive technology. In July 2006, Eastime (the Chinese name of which is unknown), an automation engineering company based in Shanghai, China, signed an agreement with Siemens. Under this agreement, Siemens acquired Eastime’s business activities; the company was then renamed Shanghai Siemens Process Analysis Co., Ltd. (SPAS) and integrated into Siemens’ Automation and Drives division as a regional company. In October, Siemens acquired CNC Water Technology, a company specializing in water treatment, in China. This is the first acquisition made by Siemens’ automation division in China in decades, demonstrating Siemens’ determination to capture the Chinese market. Like its competitors in North America, Siemens is also considering a gradual transition from discrete manufacturing to the field of process control. In 1998, the PCS7 system was introduced – a process control system based on the S7 series of PLCs. In 2003, Siemens introduced the concept of TIA (Total Integrated Automation) to enter the field of information-driven manufacturing.

Yokogawa was founded in 1915 and initially produced electric meters. In 1975, the CENTUM distributed control system was developed; together with Honeywell’s TDC2000, it was regarded as one of the world’s first DCS systems. Yokogawa mainly focuses on industrial automation and test and measurement instruments as its core business. In the early 1990s, the company acquired GTI-IA, and later Marex. In 2002, Yokogawa America acquired Measurementation, a company that specialized in gas chromatographs and infrared analysis, in an effort to expand its market share in the petrochemical industry in the United States. In 1998, Yokogawa acquired TECHCOMM, an Australian company specializing in simulation, and at the beginning of this century it bought System Plaza, thereby strengthening its foundation in open control systems. In 2002, Yokogawa acquired ANDO Electric Company, thereby expanding its market share in the instrumentation industry; however, the industry generally considered this acquisition to be an unfortunate event for both parties. In January 2006, Yokogawa sold all of its analytical instrument business to AGILENT for 100 million dollars; this business had previously been a joint venture between Yokogawa, HP, and Agilent. Yokogawa entered the Chinese market in 1978, and by donating five sets of DCS systems to the Ministry of Chemical Industry, it dominated the control systems in China’s chemical industry for 20 years. In 1986, a joint venture was established with Xi’an Instrument Factory to form Xiyi Yokogawa Company. In 2000, Yokogawa acquired all of Xiyi Yokogawa’s shares, leaving Xiyi with only a 10% equity stake; the company’s name was then changed to Yokogawa Xiyi. In recent years, Yokogawa’s systems have faced competition from domestic DCS solutions, although it still holds an advantage in large-scale petrochemical project contracting. In 2003, Yokogawa won the contract for the automation work on Shell’s ethylene project at Daya Bay, Guangdong, worth 50 million US dollars. Looking at Yokogawa’s acquisition activities, the goal is primarily to strengthen its strengths in process instrumentation. It once aimed to make a mark in the analytical instruments industry, but may have realized later that it lacked the competitiveness needed, so it decisively sold Agilent.

With a history of 120 years, ABB is a Swiss company that has been operating in the fields of power generation, power transmission and distribution, as well as electromechanical equipment; it is one of the top 100 companies in the world. In 1998, ABB acquired Alfa Laval, a company specializing in process control systems, as well as ELSAG BAILEY, another century-old company, thereby entering the field of industrial automation proper ； Prior to this, BAILEY had just acquired Hartman & Braun, a century-old German company in the instrumentation industry. Subsequently, it acquired companies such as Taylor, Asea, and Kent one after another, becoming a giant in the automation industry; it then acquired August Company and introduced its own control systems under the ABB brand. In 2000, ABB partnered with SKYVA International, an American company that developed e-commerce software; shortly after, ABB launched its Industrial IT solutions. In 2001, ABB acquired Eutech Engineering Solutions Ltd., a company involved in engineering services. From 2000 to 2002, ABB carried out a series of sales, divesting a number of companies in the areas of building automation, metering, oil and gas, and metallurgical automation, in order to focus on its power and automation business. In 2006, Raffin Electric, a company specializing in power automation, was acquired as well. To date, ABB’s control system solutions are primarily designed to work in conjunction with its own power systems, and few of them are sold as standalone automation systems in the industry. As the undisputed leader in Europe for power generation and transmission, ABB has made efforts in the field of automation, but it has yet to achieve any notable results. Compared to GE, another giant in the power generation industry, ABB’s automation business is far inferior to that of GE-Fanuc. Most of the companies it acquired were done so to improve its business performance and financial reports, with little effort invested in product development.

Our company uses HONEYWELL’s TPS with 1,500 points; we plan to launch phase two in the near future and intend to use ROCKWELL’s product.

" Our company uses HONEYWELL’s TPS with 1,500 points; we plan to launch phase two in the near future and intend to use ROCKWELL’s product. " I wouldn’t dare say that about you, but your boss definitely has a problem in the head. ““Having a problem with the brain” is an extremely derogatory term. A prominent figure in the automation sector in China once said that the more one learns about Honeywell, the more one realizes how amateurish AB is. http://bbs.ctrlsky.com/a/a.asp?B=307&ID=585690&q=1&r=198243 Go check that out; it’s my post on the differences between Honeywell and AB. . . AB is merely a role responsible for producing hardware to support Honeywell. And it will soon be abandoned by Honeywell

Rockwell initially focused on the development of aviation navigation systems. In 1985, it acquired Allen-Bradley, another company with a century-long history founded in 1903, for a staggering price of $1.65 billion; thereafter it entered the industrial automation sector, continuing to use the AB brand name. It is currently the largest automation specialist company in North America, offering a product range that includes PLCs, drive systems, motion control systems, and automation software. In recent years, it has introduced the concept of e-Manufacturing and proposed solutions for the informatization of manufacturing processes. In the past, it has been at the forefront in the field of discrete control, and in recent years it has entered the field of process control. Its PLCs are world-famous for models such as PLC-2, PLC-5, SLC500, and the latest Control Logix series. In 1998, Rockwell acquired the German PLC manufacturer Sprecher and Schuh, thereby making its entry into the European market. In 1999, Rockwell acquired Enterprise Technology Group, which developed manufacturing execution system software; Anorad Corporation, which specialized in linear motors and position control; Dynapro, which produced human-machine interface products; and EJA, which focused on security systems ； In 2000, it acquired ENTEK, renowned for shaft vibration measurement and control, Systems Modeling Corporation, famous for its simulation software, and Sequencia, which developed batch processing software, thereby entering the field of continuous process control. In 2002, it acquired Tesch (Germany), a company that develops security systems, as well as Propack Data, which had been providing manufacturing execution system solutions, and introduced the e-Manufacturing system concept. In 2005, the company acquired DataSweep, which provided information technology solutions for the manufacturing industry; in 2006, it acquired GEPA mbH, which offered manufacturing management software. Rockwell’s products have always been at the high end of the market, and their range is relatively limited; they are primarily focused on the field of discrete manufacturing, where they excel in terms of PLC technology. It was not until this century that they introduced MICRO-LOGIX and FLEX-IO to enter the lower-end market, but even there, their products remain expensive. The acquisition activities since the beginning of the 21st century indicate that Rockwell has primarily begun to enter the field of information-driven manufacturing, demonstrating clear strategic ambitions.

Founded in 1885, Honeywell is a well-established company in the international automation industry with a history of over a century; it is also one of the Fortune 500 companies. It is world-famous for developing the world’s first DCS system, the TDC-2000. The main business areas at present are three: industrial automation, aerospace instrumentation, and building automation. The DCS systems include the TDC-3000 and the newly introduced PlantView system, while the instrument series features transmitters such as the ST3000 series. In 1994, Honeywell’s European subsidiary acquired the German company Metallwerke Neheim Goke & Company, which specialized in heating system control, primarily in order to enter the European market. In 1995, the company acquired Leeds & Northrup, a subsidiary of General Signal, primarily to reduce local competition and achieve market integration; it later acquired Measurex, which specialized in control equipment for paper machines, further boosting Honeywell’s entry into the paper and pulp industry. In 1998, the security systems business of Westinghouse Electric Company was acquired ； In 1999, it acquired the renowned security monitoring company C&K Systems, thereby strengthening its position in the field of building automation. In the same year, Honeywell was acquired by the American company AlliedSignal. However, the agreement stipulates that the “Honeywell” brand will continue to be used. In 2000, GE intended to acquire the Honeywell shares held by AlliedSignal, and the two parties signed an agreement ； What could have been the biggest acquisition of the new century was ultimately aborted due to opposition from the EU. This case marked the first time in U.S. history that an acquisition between two domestic companies failed because of foreign interference, sparking a great deal of controversy in the United States. In 2002, Honeywell acquired Sensors from Invensys, and later acquired Tridelta Industries, which specialized in air conditioning system control ； In 2003, Sensotec Inc. was acquired to further strengthen the market presence in the field of sensors. In 2004, the company acquired Hysys, which was engaged in the development of simulation software; in the same year, it acquired Petrocom in Russia, a company specializing in automation engineering, clearly as a stepping stone to enter the Russian market. In 2005, Honeywell acquired Tridium Software, and later purchased the British company Novar PLC, which specializes in fire protection systems. Honeywell has consistently held a leading position in China’s petrochemical industry. The reason is, of course, first and foremost Honeywell’s expertise and experience in the petrochemical industry. However, in 1993, Honeywell signed a strategic partnership agreement with Sinopec; under the premise of \"providing world-class automation and control solutions to all Sinopec enterprises,\" the two parties jointly established Sinopec Honeywell Company, each holding 50% of the shares. As a result, the refineries under Sinopec largely preferred Honeywell’s products, which is also the key reason behind Honeywell’s strong market position within Sinopec. In 1998, the term of the joint venture expired, and due to complaints from other companies regarding unfair competition, the joint venture was not extended after its expiration. All operations have been transferred to Honeywell China. In recent years, Honeywell’s products have faced strong competition in China from companies such as Zhejiang University Control Systems and HollySys; as a result, it has largely given up on the market for small and medium-sized systems and turned to offering TURNKEY solutions for large-scale projects. For example, in the petrochemical project in Shanghai carried out by BP, Honeywell won the bid at a cost of 120 million pounds.
