Migrating Experion/C300 On-Process with Non-Redundant IOMs


Thread Starter


Our system here has redundant servers, redundant C300 controllers, redundant CF9 firewalls, but not all IOMs are redundant.

Can an online process migration be performed on all redundant devices, and then carefully and selectively perform an offline migration to each non-redundant IOM whilst keeping the plant running (setting safe values for DI/AI, and running DO/AO in a local mode). Once one IOM is done and back in service, move on to the next IOM.

Has anyone done this or know if it is possible?
