Precautions for Correct Use
Checking the Serial Number of the EtherCAT Coupler Unit
If the Serial Number Check Method setting on the EtherCAT master is set to Setting = Actual
device, temporarily change this setting to None, and then replace the EtherCAT Coupler Unit.

Setting = Actual device, a Network Configuration Verification Error will occur.
