The DeltaV I/O network > What is a CIOC?

Upgrade redundant CIOCs

  1. Using the DeltaV Controller and I/O Upgrade Utility, upgrade the standby CIOC.
  2. Once the upgrade is complete, use DeltaV Diagnostics to monitor the standby CIOC OINTEG until it becomes GOOD (this can be 3 minutes on a fully loaded CIOC). 
  3. Select the other CIOC in the redundant pair and start the upgrade.
