Set the Node Address on the Base Module
Each 1791D base module comes with its internal program set for
node address 63. To reset the node address, adjust the switches
located behind the door on top of the module. The two switches are
most significant digit (MSD) and least significant digit (LSD).
The switches can be set between 00 and 63. Use the node adjusting
tool provided in the package, or a small bladed screwdriver to rotate
the switches.
The rotary switches are read at module power up only. Switch
settings between 64 and 99 cause the module to use the last valid
node address stored internally.
The node address may also be set through RSNetWorx for
DeviceNet™, DeviceNetManager™ or a similar configuration tool.
When software configuration is used for the node address, the
switches must be set between 64 and 99.
Mount the Block(s)
The base and expansion modules mount to a panel or DIN rail,
which must be grounded before installing the module(s).
