Chapter 6
Configure and Monitor I/O
Introduction
This chapter explains how to configure and monitor I/O.
Selecting I/O Modules
When selecting 1769 I/O modules, choose:
• specialty I/O modules, when appropriate.
Some modules have field-side diagnostics, electronic fusing, or
individually isolated inputs/outputs.
• a 1492 wiring system for each I/O module as an alternative to the
terminal block that comes with the module.
• 1492 PanelConnect modules and cables if you are connecting input
modules to sensors.
Each 1769 I/O module includes a built-in removable terminal block with
finger-safe cover for connections to I/O sensors and actuators. The terminal
block is behind a door at the front of the module. I/O wiring can be routed
from beneath the module to the I/O terminals. When planning I/O
communication, consider:
• which CompactLogix I/O modules to use.
• where to place CompactLogix I/O modules.
• how CompactLogix I/O modules operate.
