Yokogawa is to release an enhanced version of its ProSafe-RS safety instrumented system later this month. 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, enhancements that make it easier to adopt and use ProSafe-RS in FGS applications.
The ProSafe-RS safety instrumented system can be integrated with the CENTUM VP integrated production control system and is widely used mainly in ESD applications all over the world. In response to the rising need for FGS solutions, this latest release includes features that make it easier to adopt and use this system in such applications. And by adding a new input/output (I/O) module and enabling the use of an alternate control network topology, users are offered a greater range of choices in their ESD and FGS applications. Cybersecurity has also been strengthened.
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. Standard FGS faceplates have been added for the integrated display of smoke, heat, and gas detector information such as gas concentration level and device status. In addition, the I/O module has a new function that can reset the detector that sends smoke and heat detection signals to the ProSafe-RS system.
Reducing total cost of ownership
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. As most safety instrumented systems rely mainly on digital I/O signals, the company has 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.
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. Vnet/IP is a control network developed by Yokogawa that features high reliability and quick response — Vnet/IP complies with the IEC61784-2 international standard. 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. This feature affords users greater flexibility when configuring their systems.
Target markets and applications for this system include use in emergency shutdown systems (ESD), burner management systems (BMS), and fire and gas systems (FGS) in process industries such as oil, natural gas, petrochemicals, chemicals, pharmaceuticals, electric power, and iron and steel.
