Functionality

PRM and PST Scheduler
Operating under PRM, PST Scheduler remotely executes the PST provided by the safety valve vendor, and records the results. Testing is efficient and well planned and results are shown on a single screen without any  additional hardware or software.  Only Yokogawa's PRM and PST Scheduler support safety valves from multiple vendors.

Features of PST Scheduler
Schedule:    Week, Month, Year, On demand
Mode:          Manual, Semi-automatic, Automatic

Maximize safety system performance
Yokogawa's ProSafe-RS Safety Instrumented System is SIL3 certified even in a single modular configuration. Execution of PSTs on a fixed schedule is key to ensuring that a safety system will function correctly in an emergency. The combination of ProSafe-RS and PRM with PST Scheduler not only simplifies the management of safety devices, it maximizes safety system performance. In addition, no additional wiring or hardware such as a multiplexer is needed to manage safety devices.

Optimal flexibility in valve selection
The Vigilant Integration Partners (VIP) program is an open, non-exclusive, standard-based, and interoperability-driven initiative that enables users of Yokogawa's ProSafe-RS Safety Instrumented System and PRM asset management system to use best-in-class field devices from Dresser Masoneilan, Flowserve Corporation, Metso, and SAMSON AG.
