13-7 Emergency Messages

EtherCAT Slave Terminals are able to report emergency messages to the EtherCAT master by using
the SDO communications if they detect errors.

13-7-1 Enabling/Disabling Emergency Message Notification

You can use SDO communications to specify whether notification is provided with emergency mes-
sages.
The applicable indexes are a subindex of 05 hex: (Flags) in index 10F3 hex (Diagnostic History).
The settings are as follows:
Setting value
0000 hex
0001 hex
When the Unit power supply is turned ON, the EtherCAT Slave Terminal always starts with the No Noti-
fication setting.
If you want to use a Slave Terminal with emergency message notification, enable it every time you turn
ON the power supply.
Emergency messages cannot be sent while there is an EtherCAT communications error.

Additional Information
If you use an NJ-series CPU Unit, you can use the setting to provide notification just by turning
ON the Unit power supply. Set the Diagnosis History/Flags setting parameter for the EtherCAT
Coupler Unit to 1 (Notification) from the Sysmac Studio.

13-7-2 Error Logs

A log of the errors that were reported with emergency messages is saved in the non-volatile memory of
the EtherCAT Coupler Unit. This log can save up to 128 errors. You can read the errors with SDO com-
munications. The indexes to read are from subindexes 06 to 85 hex (Diagnosis Messages 1 to 128) in
index 10F3 hex (Diagnostic History).
The error log saves errors sequentially from Diagnosis Message 1 to Diagnosis Message 128. The
count returns to Diagnosis Message 1 on the 129th error. Even if an emergency message cannot be
sent to the EtherCAT master, it is still saved in the error log. Errors related to the non-volatile memory
are not saved in the error log.
