Yokogawa has announced the release of an enhanced version of the Prosafe-RS Safety Instrumented System, Prosafe-RS R2.02.00.
The enhanced version of the software adds an output module for use with alternating voltage power sources and offers improved maintenance and documentation functions, which the company believes make the system ideal for widely distributed upstream processes, including wellheads and pipelines.
The enhancements meet users' requirements for safety instrumented systems, and strike the balance between improved operational efficiency and safety in upstream and downstream processes.
The Prosafe-RS platform now offers connectivity with the control and monitoring functions of Yokogawa's Stardom network-based control system, thereby securing the safety of widely distributed production facilities.
Yokogawa has achieved connectivity between Prosafe-RS, Stardom, and the Fast/Tools Scada system over a single network based on the Vnet/IP real-time control bus and dedicated to upstream processes.
As a result, Fast/Tools can monitor both the Stardom and Prosafe-RS systems in an integrated manner.
An output module has been added for connecting directly to devices such as emergency shutdown valves that use a 100-120 VAC power source.
This eliminates the need to set up relays for such devices, simplifying system configuration and improving maintenance efficiency.
This module complies with the IEC61508 international safety standard and is certified to the SIL3 Safety Integrity Level as defined by the IEC.
At SIL3, the risk factor for a plant where safety measures are not in place has been reduced to a range from 1/1000 to 1/10000.
A function has been added that makes it possible to change the operational parameter settings in an I/O module without disrupting input/output to/from any connected equipment.
It is no longer necessary for these settings to be done manually.
An enhanced documentation function makes it possible to modify the format of a spreadsheet for printing out data.
Users are free to select whatever format is most efficient for displaying the data.
Target markets include oil, natural gas, petrochemicals, and other process industries that use systems for emergency plant shutdown, fire prevention/fighting, and burner management.
