LEMCOM CANopen® – User manual

9 EMERGENCY MESSAGES

The CANopen® LEMCOM module's internal errors are indicated by emergency messages sent over
the CAN bus.
An emergency message frame is built as follows:
Server (LEMCOM)  Client (master)
CAN-ID Emergency
(80h+ID) code L
0A0h 00h
Emergency messages are transmitted over the CAN bus, but they do not need to be confirmed by
the consumer(s).
A message is sent when a new error is detected and when it disappears.
The table below lists the emergency codes supported by the LEMCOM module:
