Configuration Using the 1769-IF4XOF2 Combination Analog Module with a CompactLogix System C-7

This Configuration tag is 198 words long. Only the first 6 are needed
to configure this module. The remainder of the words in this tag
should be a value of 0 decimal.

The 6 words of configuration data are entered in the following tags,
assuming the module was configured in slot 1:

The four input channels for this module are not configurable. Each
input channel supports either 4 to 20mA current or 0 to 10V dc
voltage. This choice is determined by the module terminal to which
you are wired. There is a current and a voltage terminal for each
analog channel.

TIP

CompactLogix controllers do not yet support Hold
Last State (HLS) or User Defined Safe State (UDSS)
for Fault and Program modes for outputs. Analog
modules, by default, hold outputs in their last state if
the connection is lost to the controller (Fault State) or
if the controller is placed into the Program mode or
Faults (Program State).
