Judging by your questions you are trying to develop a critical system to some SIL level or to standard 61508. Yes Oliver, I am working for a SIL certification project where as you mentioned the requirement has to be developed. But as you said "supply monitor chip with an integral WDT" is it using another WDT externally or another WDT within the controller. Can you elaborate it please |
