Yokogawa will release an enhanced version of the ProSafe-RS safety instrumented system.

Yokogawa Electric Corporation will release an enhanced version of the ProSafe-RS safety instrumented system April 26.

This latest release, R4.03.00, includes an improved engineering function for configuring fire and gas systems (FGS) and new operation faceplates for the FGS operation and monitoring screens. These enhancements make it easier to adopt and use ProSafe-RS in FGS applications.

In the oil, natural gas, petrochemical, chemical, and other energy and basic materials industries, various safety measures must occur to prevent accidents and protect the environment. This includes the use of a safety instrumented system, which can secure plant safety by functioning as an emergency shutdown system (ESD) that detects abnormal conditions and safely initiates emergency shutdowns, and by functioning as an FGS.

Yokogawa’s ProSafe-RS safety instrumented system can integrate with the CENTUM VP integrated production control system.

Since releasing this system in 2005, Yokogawa has continued to strengthen its functions to satisfy customer needs. In response to the rising need for FGS solutions, this latest release includes features that make it easier to adopt and use this system. By adding a new input/output (I/O) module and enabling the use of an alternate control network topology, users have a greater range of choices in their ESD and FGS applications. Cybersecurity has also been strengthened.

Here are some of the enhancements to the system:
1. Software components (function blocks) that define the operations and functions to be performed when smoke, heat, and/or gas is detected, an essential aspect of any FGS application, have been added to the ProSafe-RS engineering functions.
2. Yokogawa provides an N-IO (Network-IO) I/O device with channels that can be configured by software to handle either analog or digital signals. The company added a new I/O module to its lineup that is used for only the input or output of digital signals. This new module reduces the total cost of ownership for users.
3. For the Vnet/IP real-time control bus, ProSafe-RS has relied on the star network topology, in which all devices are connected to a central hub. The new ProSafe-RS is also compatible with the ring topology, in which devices are connected to each other in the shape of a ring.
4. As a result of enhancements made to the ProSafe-RS engineering station’s software security functions and changes to the Windows security settings, users can now set their systems to a higher security level.
