Isolated Analog Output Modules

Configuring Each

Output Channel

After installing your module, you must configure each channel by setting

bit values in each configuration word. Output words 4 and 5 of the output

image file (addresses O:e.4 and O:e.5) configure channels 0–1 and 2–3,

respectively.

Channel 1 Configuration Byte

Channel 0 Configuration Byte

O:e.4

Address

Channel 3 Configuration Byte

Channel 2 Configuration Byte

O:e.5

A detailed explanation appears in the following table:
