"Excerpt from the Exida White Paper: A Hybrid Fault Tolerant Architecture & New Levels of Performance, Availability and Safety Integrity
The RTP 3000 SIS System has a hybrid architecture that uses a set of advanced design techniques to provide SIL 3 safety integrity and high availability. Safety integrity and high availability are achieved on a system that also provides an unusual level of architecture flexibility and computing speed (12 msec. scan rates). This combination of safety integrity, high availability, flexibility and performance sets new levels of expectation among safety … Read MorePLC users.
A Markov model was developed to analyze the behavior of the RTP 3000 SIS system under fault conditions for two common configurations. Using the Markov models and the failure rates from the FMEDA, example average Probability of Failure on Demand (PFDAVG) and Mean Time To Fail Spurious (MTTFS) values are calculated. The results confirm the level of high safety integrity and high availability achieved by the design."

"The RTP data acquisition cards were installed and have been running in our plant unit 2, since 1987. In that entire running time, on 24×7 basis, we have had only one card failure. This is a remarkable achievement considering the environment these cards have been running in and that, during 2001, we also replaced the computer system, all the display stations and upgraded the network. They ALL became obsolete, but we kept the RTP I/O which is still to this date, flawlessly performing its functions. This was the main reason that when it came time to upgrade the unit 3 plant process computer, … Read Morethe plant decided to stay with RTP. Their equipment is reliable, durable and is withstanding the test of time."

"We looked at several TUV/SIL rated system manufacturers and chose RTP based on the fact that RTP was the only one that could provide everything that our clients were looking for."

"During periodic maintenance at BaoSteel’s 2030 cold strip CM09 color coating machine group, primary and secondary replacement ovens from the Stein Heurtey Corporation of France were scheduled for installation. Other replacement equipment included the incinerator, dry air supply and flue gas systems. After evaluating several industrial control systems from different venders, Stein Heurtey and BaoSteet selected the RTP 2200 Hybrid Control System and Citect (Ci Technologies, Inc.) as the primary control system for the machine group."

"The desulfurization and sulfuric acid equipment previously used by BaoSteel Chemical Ltd. was imported from NKK Japan and based on Foxboro’s Spectrum control system. BaoSteel was facing a Y2K problem with the Spectrum control system and maintenance costs were escalating. In order to optimize the process, decrease operation costs, and increase profits, in November 1999 it was decided to upgrade the control sytem. The new control sytem includes the latest generation RTP 2200 Hybrid Control System, which combines the advantages of both the PCL and DCS. This system includes redundant I/O car … Read Mores, I/O buses, target node controllers, power supplies, network communication interfaces, Citect I/O servers, and Citect I/O operation stations."

"The 135 Ton/Hour Boiler Computer-Control System at BaoSteel’s Energy Department is using the new generation RTP 2200 HCS (Hybrid Control System), which combines the features and benefits of the PLC and DCS. This system includes full redundancy of I/O cards, I/O buses, CPUs, power supplies, network communications, Citect I/O servers, and Citect I/O operation stations."

"The solid waste incinerator at the Southerly Wastewater Treatment Plant, located just south of the City of Columbus, Ohio, was previously operated using a circa 1970’s vintage control system. Beyond its useful life and subject to Y2K issues, management decided to replace the system. Requirements included a simplified configuration and programming environment, minimal time to install and commission, and an open architecture non-obsolescent design that was easy to operate and maintain. The goal was to acquire a high-performance, accurate, and stable control system that would help the city … Read Moreo reduce costs associated with operating the incinerators. Over twenty PLC and DCS vendors competed in the bid process. After careful evaluation, the project was awarded to the Coleman Instrument Company of Cincinnati, Ohio in October 1999. Installation of the new system began in December and completed the first week of February 2000."

"New measurement systems have been installed at the Forsmark Sweden nuclear power plant. These systems collect operational data from two of the plant’s three reactors. Each system consists of approximately one thousand 0-10V analog points, which are collected by the data collection nodes located throughout the facility."

"The control system for six 220-ton boilers and three 100MW turbines at the Fuxin power plant was using legacy analog instruments, which were reaching the end of their life expectancy and malfunctioning more frequently. The system upgrade was awarded to Citect (Ci Technologies Inc) in June 1999. The new control system uses RTP’s 2200 HCS (Hybrid Control System), which combines the features and benefits of the PLC and DCS. Full redundancy is provided for I/O, busses, controllers, power supplies, network communications, Citect I/O servers, and Citect I/O operator stations. After the control … Read Moresystem was updated, total automation of head main steam control of six boilers, DEH (Digital Electrical Hydrodynamic) control of the six turbines, network communications, and data sharing of whole system were successfully implemented."

"Product designers and end users can both benefit when a solution uses open standard components, as demonstrated by the design of a system to monitor vibration in power turbines. The user benefits from having an assured upgrade path and maintenance capabilities that can be independent of arbitrary technology changes and from price increases or policies imposed by a manufacturer who may be indifferent to the market in which the user exists. Future upgrades can be incremental, using installed sensors, rather than requiring capital investments to replace entire systems. Use of open standard compon … Read Morents enables the product designer to concentrate time and resources on adding the intellectual property that constitutes their chief value added benefit. This means he can also incorporate the latest technology and achieve high speed-to-market, both of which create a competitive advantage over proprietary solutions."

"Qinghe Power Plant is located in Qinghe, Tielin County, LiaoNing Province, China. With maximum capacity of 1,200 MW, it was formerly one of the largest power plants in China. In 1999, the decision was made to upgrade its chemical water treatment plant instrumentation. The job was awarded to Citect (Ci Technologies Inc, Shanghai). After upgrading the system, the level of automation at the water treatment plant has increased, while process costs have decreased, and profits retrieved by the project ahave met the plant’s investment expectations.
