OVERVIEW
(3) Enriched operation history and error history
The CPU module can record a total of 3000 operation/error history entries for the
details of the CPU module operation by the user and for the errors occurred in the
CPU module or the CC-Link Safety system.
Recording the details of the CPU module operation by the user into the operation/
error history clarifies the occurrence order of operations and errors. Troubleshooting
becomes easier by confirming the error/operation history.
The contents recorded in the operation/error history are shown in Table1.2.
