Cycle time
monitoring
Possible (Unit stops operating if the cycle is too long): 10 to 40,000 ms (Unit: 10 ms)

FAL and FALS instructions can be used with the CJ1-H and CJ1M CPU Units to simulate errors.
Error logUp to 20 errors are stored in the error log. Information includes the error code, error details, and the time the error occurred.
A CJ1-H or CJ1M CPU Unit can be set so that user-defined FAL errors are not stored in the error log.
