Hi… I have a long history of CSV work, but little exposure to PLC validation. My assumptions which may make an a… of me, are that much of the same documentation is required, e.g. URS, Risk Assessment, FRS, SDS, Validation Plan, Test Plan, IQ, OQ, PQ, Validation Summary Report. I would probably add FEMA for each controller. Am I on the right track? Can anyone provide some guidance in difference in documentation of each system? Thanks.
