Emergency messages (EMCY)
An emergency is sent when a failure occurs either on the bus or within the device. Within an EMCY message the
error is coded.
Object 1014h defines the COB-ID of the emergency message. The default value is
80h + device node-ID (1 - 127). BasicCAN Frames or ExtendedCAN Frames can be used (Bit 29 = 1).
General structure of an emergency message:
80h+ID

Error Code L
Error Code H Error Reg.
