01: Local node error	01	Local node not part of Network	Add to Network.
	02	Token time-out, node address too large	Set the local node’s node address below

	03	Number of transmit retries exceeded	Check communications with ECHOBACK

	04	Maximum number of frames exceeded	Either check the execution of events in the
			network and reduce the number of events

	05	Node address setting error (range)	Correctly set the Controller Link BIOS /N
