Configuration Plugs

You need to set configuration plugs on the remote I/O adapter module to
use 32-point I/O modules, . You access the plugs through the access hole
on the left side of the module (Figure 2.2). Each plug is inserted on two
pins of a three-pin connector. Thermocouple Input Modules (Cat. No.
1771-IX and -IY) are not compatible with 32-point I/O modules.

Important: When you set the configuration plugs in the left position, you
can use 32-point I/O modules and any addressing method, but you cannot
use Cat. No. 1771-IX or 1771-IY modules. When you set these plugs in the
right position, you can use 1771-IX and 1771-IY modules and any
addressing method, but you cannot use 32-point I/O modules. If the plugs
are set incorrectly, addressing errors will occur.
If you need to use a thermocouple module and 32-point I/O modules in the
same remote chassis, use the 1771-IXE Thermocouple/Millivolt Module
(Cat. No. 1771-IXE).
