14 Compact I/O Analog Output Module

Publication 1769-IN087A-EN-P - August 2009

Wire Size and Terminal Screw Torque

Each terminal accepts two wires with the following restrictions.

Configure the 1769-OF4 Module

The following I/O memory mapping lets you configure the 1769-OF4 module.

Output Data File

For each module, slot x, words 0…3 in the output data file contain the control

program’s directed state of the module’s analog output channels. Word 4 contains

the cancel output-channel-clamp alarm control bits.

The bits are defined as follows:

• SGN = Sign bit in 2’s complement format.

• NU = Not used. Bit must be set to 0.

• CHOx = Cancel High Clamp Alarm Latch for Output x: Allows each output

high-clamp-alarm latch to be individually cancelled. NOTE: Cancel = 1.

• CLOx = Cancel Low Clamp Alarm Latch for Output x: Allows each output

low-clamp-alarm-latch to be individually cancelled. NOTE: Cancel = 1.
