Set the Node Address on the Base Block
Each base block comes with its internal program set for node address
63. To reset the node address, adjust the switches on the front of the
block. The two switches are most significant digit (MSD) and least
significant digit (LSD). The switches can be set between 00 and 63.
The rotary switches are read at block power up only. Switch settings
between 64 and 99 cause the block to use the last valid node address stored
internally
.
Figure 2.1
The node address may also be set through RSNetWorx for DeviceNet
or a similar configuration tool. When software configuration is used
for the node address, the switches must be set between 64 and 99.
