DeviceNet MAC ID (Node Address) Switches
Two 10-position rotary switches, shown below, are used to set the MAC ID (node address).
The MAC ID is an integer identification value assigned to each node on the DeviceNet network.

Figure 14: Devicenet MAC ID Switches
The valid MAC ID switch positions are 0 to 63. Use the switch on the left to set the most significant digit
(MSD), that is, the factor of ten (10, 20, 30...60). Use the switch on the right to set the least significant digit
(LSD), that is, the increments of one (1, 2, 3...9). The switch positions are numbered in a clockwise direction,
to correspond to the increasing address values.
Note
Setting the switches to a value that is greater than 63 is the same as setting the rotary switch to
the “PGM” position (the baud rate is read from the non-volatile memory).
Note
The MAC ID switch on the top of the device must be set to the network (PGM) position before
power up in order for changes to be made over the network. Any changes in the rotary switch
positions after power up are ignored.
