Network Status Indication in the M1 Ethernet Module

Overview	The M1 Ethernet Module can provide I/OBus network status via the Module Status
	function in the programming panel or by a STAT element in user logic. The fourth
	word of the status element contains information regarding the integrity of the
	network.
Operation
	The I/OBus status word contains a valid value only when the processor is running.
	A zero value indicates that normal I/OBus communication is occurring.
	A non-zero value indicates a problem.
Failure
	If there is a communications error, bit values in the I/OBus status word contain
Indication	information on the failure mode, as follows:
BITS 0 - 14	These bits contain a value from 1 to 255, signifying the network position of the
	module that cannot be reached. For example, a value of 8 indicates a
	communications failure in accessing the 8th module on the network.
BIT 15	This bit contains a value of 0 or 1.
	A value of zero indicates a general communication failure, for example, no power to
	the module or a break in its input cable.
	A value of 1 indicates that communication is possible, but the I/OBus ID received
	from the module does not match the module type contained in the traffic cop for
	that position.
