Tokyo, Japan - December 17, 2014
Yokogawa Electric Corporation announces that it will release ProSafe®-RS R3.02.20 on December 26. This enhanced version of the ProSafe-RS safety instrumented system (SIS) offers improved connectivity with the ProSafe-SLS SIS, enabling the status of both systems to be monitored onscreen by operators of the CENTUM® VP integrated production control system. In addition, R3.02.20 offers enhanced support of widely used open communication protocols, improving connectivity with other companies' SCADA*1 software.

In the oil, natural gas, petrochemical, iron & steel, and other energy and basic materials industries, plant safety is a growing concern. There is thus a rising demand for SISs that can help to prevent accidents by detecting abnormal conditions and initiating actions such as an emergency plant shutdown. Yokogawa provides two different SISs, the programmable ProSafe-RS and the solid-state*2 ProSafe®-SLS, and customers select which systems to utilize based on their facilities' requirements. For customers who use both SIS systems, there is need for a solution that will enable the status of both these systems to be monitored in an integrated manner.
ProSafe-RS is a programmable-type SIS that was released in February 2005. It can be fully integrated with CENTUM® series integrated production control systems, and is certified for use in SIL3*3 applications. Since its release, ProSafe-RS has been implemented in more than 1,500 projects around the world.
ProSafe-SLS is a solid-state safety instrumentation system that was released in 1997. Equipped with a magnetic core, ProSafe-SLS can be used in SIL4 applications. This system is in use at approximately 300 locations around the world, primarily in high-integrity pressure protection system (HIPPS) applications.
*1 Supervisory control and data acquisition. SCADA software is used to monitor and control production processes.
*2 A simple hardware design that employs a magnetic core and a semiconductor device
*3 Safety integrity level. SILs are defined by IEC 61508, a functional safety standard for electrical and electronic equipment that was developed by the International Electrotechnical Commission (IEC). There are four levels: SIL1 to SIL4. For a plant where safety measures are not in place, SIL3 reduces the risk factor to 1/1000-1/10000, and SIL4 reduces it to 1/10000-1/100000.
For use in emergency shutdown systems (ESD) and fire and gas systems (FGS) in oil refineries, natural gas processing facilities, and petrochemical plants, and in oil and gas production facilities
