Diag Messages
Diag Messages designates a system for the transmission of messages from the EtherCAT Slave to the
EtherCAT Master/TwinCAT. The messages are stored by the device in its own CoE under 0x10F3 [} 97] and
can be read by the application or the System Manager. An error message referenced via a code is output for
each event stored in the device (warning, error, status change).
See the Diag Messages notes [} 150] regarding this.
