7 COMMUNICATION FUNCTION

7.3 System Management Function

D.Station supports the "Transmission/reception of the MAC ID duplication detection signal"
function as a system management function. Transmission/reception of the detection signal
is automatically done by the D.Station. The MAC ID duplication detection signal is a frame
that the D.Station or the DeviceNet communication control program of a specific device
broadcasts upon startup or bus OFF recovery. This signal secede either or both of the nodes
having a duplicate MAC ID from the network, thereby leaving the line unaffected.
