Product Description

The GRVSW-671FA is a high-integrity system software package developed for ProSafe-RS Safety Instrumented Systems (SIS). This Real-Time Operating System (RTOS) is specifically designed for Safety Control Stations (SCS) such as the SSC50D and SSC60D controllers. It provides deterministic execution of safety logic, ensuring that Emergency Shutdown (ESD), Fire & Gas (F&G), and other critical safety functions are executed with precise timing. The software supports duplexed CPU architectures and dual-redundant Vnet/IP communication, enabling SIL3-level safety integrity for industrial processes.

Technical Specifications

Industrial Application Scenarios

The GRVSW-671FA is essential for facilities where safety-critical automation is required. Typical applications include:

• Emergency Shutdown (ESD) systems in oil & gas plants

• Fire and Gas (F&G) monitoring in petrochemical and chemical facilities

• Burner Management Systems (BMS) in power generation

• SIL3-certified safety control loops across process industries

The software ensures safe, deterministic operation of ProSafe-RS hardware and maintains synchronized communication with CENTUM VP DCS systems while isolating safety functions from standard process control.

Technical FAQs

1. How does GRVSW-671FA differ from GRVSW-668FA?
The 668FA is designed for standard process control (FCS) in CENTUM VP systems, whereas the 671FA is specialized for safety-related control in SCS, including SIL3-certified logic execution and enhanced diagnostics.

2. How is the software delivered?
GRVSW-671FA is typically supplied as a licensed firmware bundle tied to the CPU’s electronic ID. It is loaded during initial system commissioning or via certified firmware upgrades.

3. Does it support redundancy?
Yes. The software fully supports duplexed CPU configurations with “Pair & Spare” synchronization, ensuring uninterrupted safety control even if one CPU fails.
