Emergency Messages¶
Emergency messages are used to signalize device errors. An emergency message contains a code that clearly identifies the error (specified in the communication profile DS-301 and in the individual device profiles DS-40x). The following table shows some of the available error codes. Emergency messages are automatically sent by all CANopen® modules.
