Compact Logix 5069-L306ER Energy Storage Fault
The energy storage module that is internal to the CompactLogix 5370/5380 controllers can still log a minor fault, a Type 10 Code 14. This would indicate a hardware anomaly with the internal ESM indicating it should be replaced. However, since the internal ESM can not be replaced the entire controller will need to be replaced.
