7.12.5 Emergency telegram
Emergency messages are triggered by device-internal mechanisms and reported to the master by
the mailbox service of EtherCAT. If a state change cannot be executed for an EtherCAT gateway, it
is reported by a corresponding emergency message.
For a more detailed error description, the EtherCAT master reads out the AL status code (AL =
application layer). This is located in the EtherCAT coupler in the register ’0x0134’. Here you can find
the EtherCAT-specific error codes
( 401) and Manufacturer-specific error codes ( 402) .
Structure of the emergency message
The emergency messages are displayed as raw data in the »PLC Designer« and entered in the
logbook. Within this telegram, the reported error is entered as 5-digit hex value starting from the
"data:" information. The structure of the hex value corresponds to the bytes 3 ... 7 in the above table.
