SIS redundancy issue
Thread Content
This post was last edited by pointgrey on 2015-7-22 at 13:04. I have a question: Regarding SIS redundancy, if the field instruments are not redundant, does it still meet the specifications? Is the system considered redundant?
Putting the systems of these two companies in the same group is like looking for a fight. Those two companies are fierce competitors, and their customers also have their own preferred groups; would it be appropriate to combine them into one group, in the OP’s opinion?

Answering this question involves too many aspects; you’d better take a look at the SIS system design specifications and articles related to SIL levels
