Yokogawa Releases ProSafe-RS R4.05.00

Yokogawa Electric Corporation has recently announced the release of ProSafe-RS R4.05.00, an enhanced version of the ProSafe-RS safety instrumented system.

ProSafe-RS is a core product of the OpreX Control and Safety System family.

This latest version of ProSafe-RS has a new processor module with a Yokogawa-developed microprocessor unit (MPU).

The use of an MPU of Yokogawa’s own design eliminates the risk of disruptions caused by the modification or discontinuation of commercially available electronic components, ensuring the long-term stable provision of the ProSafe-RS system.

This version of ProSafe-RS also features an enhanced function that speeds up system software upgrades and a new function that helps to prevent operator errors. With these enhancements, Yokogawa is helping to ensure safety and sustainable operations over the entire lifecycle of plant operations, from commissioning to end of service.

ENHANCEMENTS

• New S2CP471 processor module with Yokogawa-developed MPU: The safety control station (SCS) is a key component of the ProSafe-RS system, and the processor module is a vital component of the SCS. For this latest version of ProSafe-RS, Yokogawa has developed the S2CP471 processor module. To ensure long-term product lifecycle support (supply chain security) and thereby contribute to the overall stability and continuous of plant operations, Yokogawa has incorporated a new MPU of its own design in the S2CP471 processor module.
• Ability to upgrade system version while SCS is operating: To ensure safe plant operations, the latest security features and other countermeasures must be implemented in plant system software. Until now, upgrade to the SCS software could normally once every few years because it required a shutdown of related production processes.
• Addition of forced I/O viewer to improve visibility and plant awareness: The forcing of I/O and application program variables is usually necessary during plant commissioning and maintenance. Identifying whether specific I/O and program variables are forced has required consultation with safety engineers or the looking up of such information in work shift documentation.
