Checking and Responding to Event Codes

When an error occurs, you can view all current errors according to their Sysmac Error Status level
through the communications master.
You can check the errors that are managed by the EJ1 EtherCAT Slave Unit through the Sysmac Error
Status.
You can connect the NJ/NX-series CPU Unit and the Sysmac Studio to check an error detected by the
EJ1 EtherCAT Slave Unit with the event code given in Sub Info 3 under Emergency Message Detected
on the Controller Event Log Tab Page. Refer to Event Code List on page 7-7 for details on event codes.
For non-OMRON masters, you can check the current error details by reading data from the objects at
indexes 2003 hex and 2004 hex. For details, refer to A-3-6 Manufacturer-specific Object 1 on page
A-15 under A-3 CoE Objects on page A-9.
