What is a Logic Solver? – Safety PLC
SIS Logic solver safety functions to be made independent and separated from the basic process control system (BPCS).
SIS Logic solver safety functions to be made independent and separated from the basic process control system (BPCS).
Proof testing is very critical to ensure all SIS Sensors. Logic solver & Final control elements are functioning healthily as designed.
Safety Instrumented System is to be designed carefully considering common cause failure, and techniques to overcome the problems.
In this article, you will learn about the Safety Instrumented System (SIS) design, terminologies, work process, and other factors.
Safety Requirement Specification (SRS) form gives a full view of SIS design, configuration of sensors, logic solver & Final control element.
