DVC6200 is used in DeltaV and AMS environmen. Now in DeltaV control studio shows that AO module out and BKCAL_OUT were in red with cross mark. It stopped to response DCS input. DVC6200 could be open in AMS and ValveLink Snap on. We found there is no any alert and is in "In Service" mode. In DeltaV diagnostic, OInteg is BAD, Status is “Configuration Scale Does Not Match Device”. We checked input range at device is 0%-100% which is same as AO module setting.
After change mode from In service to out of service and back to in service, this issue is resolved.
What is the reason and what should I do to prevent this happen again. Thanks
Daniel
