C-10 Configuration Using the 1769-IF4XOF2 Combination Analog Module with a CompactLogix System

When the Input and Output tags for the 1769-IF4XOF2 module are

expanded in the CompactLogix Controller Tags screen, they look like

the following:

The analog data is presented to the controller in Raw/Proportional

format. This means the data for the two possible analog types is:

0 to 20mA Raw/Proportional data range 0 to 31104 decimal

0 to 10V dc Raw/proportional data range 0 to 31104 decimal

TIP

This module only uses bits 7 through 14 to represent

the analog data.
