I/O Module Replacement or Upgrade Issues
After upgrading or replacing an I/O module, the following conditions require additional troubleshooting to resolve:
•
Communication Errors
•
Download Errors
•
Active Diagnostics
•
Mismatched Revision

If one I/O pack has different diagnostics than the other two in a TMR set, it is typically due to an incomplete download
or mismatched revision. If neither of these issues can be resolved, try replacing the I/O pack with a new one of the same
hardware form as the other two in the TMR set.
