Resetting Slave Errors
You can reset errors in the EtherCAT Master Function Module to reset slave errors. However, process
data communications between the EtherCAT master and EtherCAT slave must be active to reset a
slave error.
If process data communications with the slave are not active, check the slave after you reset errors in
the EtherCAT Master Function Module to see if process data communications are active. Then, to reset
the error in the slave, reset errors in the EtherCAT Master Function Module again.
