NAME	Color	Status	Indication

Modbus Plus	Green	Six flashes	The 1560-MBP is working normally in
Port Status		per second	that it is successfully receiving and
			passing the token. All nodes on the link
			should be flashing this pattern.

		One Flash	This node is off-line after just being
		per second	powered up, or after exiting the four
			flashes per second mode. In this state,
			the node monitors the network and
			builds a table of active nodes and
			token-holding nodes. It remains in this
			state for five seconds, then attempts to
			go to its normal operating state.
