Set the Node Address on the Base Module
The node address for network connection is set using two 8-bit DIP
switches. To set the node address, lift the door containing the status
LEDs on the top left side of the module. The switches are read at
module power up only. The rack address setting and the starting
quarter setting are described below.
DIP Switch Settings
The 1791R DIP switches are described in the table below .
IMPORTANT
It is important to monitor the rack fault bit.
When installing a system for the first time, it is
possible to mistakenly put devices with duplicate
rack addresses on the same network. Blocks
with duplicate addresses may in certain instances
cause outputs to toggle on/off until the duplicate
address error is corrected.
