Emergency messages

Emergency messages are messages that are actively sent from the device to the EtherCAT

®

master if certain events/prob-

lems occur. They are an unverified service which is based on CoE. In this way, all errors can be indicated to the master by

the slave. This takes the form of messages which are specified in ETG.1000.6.

An emergency message is structured as follows:

The following emergency messages are supported by the device:

The device sends emergency messages for an incoming and outgoing error. Once the problem has been

solved, an emergency message with the error code 0000

The value of the corresponding bit in the error register is then 0. The diagnostic data value does not change.
