Tokyo, Japan - September 27, 2016
Yokogawa Electric Corporation announces that it will be releasing ProSafe®-RS R4.02.00 on September 28. With this latest release of the ProSafe®-RS safety instrumented system, a number of functional safety management (FSM) related functions have been added to the Automation Design Suite (AD Suite) engineering environment for ProSafe-RS that will support our customers in ensuring safety throughout the plant lifecycle.
In energy and basic materials industries such as oil, gas, petrochemicals, and chemicals, various safety measures must be taken to prevent incidents and to protect the environment. One such measure is the introduction of safety instrumented systems, which can safely initiate an emergency plant shutdown if a critical failure is detected.
The initiating causes of such incidents have been investigated by regulatory bodies that have identified poor clarity in requirements definition and communication as the major contributing factor. Further to this, increased attention has been paid to the role that FSM plays throughout the plant operational lifecycle in keeping the risks of unsafe practices or failures within an acceptable range. Interest among our customers has thus been rising in ensuring the safety of their plants by obtaining compliance with the IEC 61508 and IEC 61511 international standards*1 on functional safety. However, FSM is a complex subject requiring a diversity of expertise to carry out tasks such as deciding policies, creating management systems, drawing up plans, managing their execution, and training personnel. To help customers accurately define, test, and understand their systems and to simplify the task of ensuring that a system remains in compliance with the IEC 61508 and IEC 61511 functional safety standards during the engineering phase and while in operation, Yokogawa has added new functions to AD Suite.

The functions described above have been achieved using iDefine for ProSafe-RS, an FSM tool developed by Trinity Integrated Systems*2. iDefine for ProSafe-RS can be purchased only from Yokogawa.

Released in February 2005, the ProSafe-RS safety instrumented system helps prevent accidents by detecting abnormal conditions in plant operations and initiating emergency actions such as a plant shutdown. An independent certification body has certified that ProSafe-RS conforms to the IEC 61508 international safety standard and can be used in SIL3*3 applications. Unlike conventional safety instrumented systems and distributed control systems, which are regarded as having different roles and functions and operate separately, the operation of ProSafe-RS and the CENTUM integrated control system can be fully integrated. ProSafe-RS is highly regarded by users and has been installed in more than 2,000 projects worldwide in the 11 years since its release.
*1 IEC 61508 is a standard for the functional safety of electrical/electronic/programmable electronic safety-related systems that was established by the International Electrotechnical Commission (IEC). IEC 61511 is based on the IEC 61508 standard and concerns the safety instrumented systems used in the process industry sector.

*3 Established by the IEC, a safety integrity level (SIL) indicates the relative level of risk provided by a safety function. SILs 1 through 4 are defined by IEC 61508. At SIL3, the risk factor for a plant where safety measures are not in place is in a range between 1/1,000 and 1/10,000. At SIL4, the risk factor is in a range between 1/10,000 and 1/100,000.
