error control message

The CANopen error control messages are mapped to a single 1-byte CAN data frame assigned with a fixed identifier that is derived from the device's CAN open node-ID. It is transmitted as boot-up message before entering the NMT preĀ­ operational state after initialization. It is also transmitted periodically by the device (heartbeat) or, if remotely requested (only in Classical CAN implementations) by the NMT master (node guarding).
