Setting the Rack Address
DIP switches 8 through 3 on SW 1 set the rack address for the
Remote I/O module. Each Remote I/O device must have a rack
address that the controller can recognize. Each rack contains 8 words.
Important: When using a PLC-2 family processor, add 1 to the rack
number set on the Remote I/O module DIP switches to
your PLC code. The PLC-2 cannot have a Remote I/O rack
numbered zero, so add a value of one to the rack number
value when writing your PLC code.
Figure 2.12
To edit the rack address, you need to:
1. Refer to the following table to determine the settings for SW1.8
through SW1.3:

Important: Not all controllers support all of these node addresses.
Refer to the documentation for your controller. The
maximum number of devices on a Remote I/O link is 32.
2. Slide the switches to their appropriate positions.
Settings take effect when a module or board first receives power.
When you change a setting, you must remove and then reapply power
for the new setting to take effect.
