8.9 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
Note 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.
