9/Series Adapter Modules for
1771 and 1746 I/O Devices

Assign an address to the module using the dip switch S1 found on the side
of the 1746I module. Figure 10B.4 shows the location of the node address
switch assembly on the 1746I module.

Other 9/Series I/O devices (such as an HPG or MTB panel) on the 9/Series
fiber-optic ring can have the same node address as the 1746I module.
However, devices of the same type (multiple 1746I modules) must each
have a unique node address. Each 1746 I/O ring adapter is assigned a
unique node address in the I/O assignment file of ODS (refer to your PAL
reference manual). This address corresponds to switch assembly S1 on the
1746I module.
Set switch assembly S1 to correspond to the node address as shown in
Table 10B.C.
