ControlLogix Isolated Analog I/O Module Features
Chapter 2
The following examples are instances where you need to use module inhibiting:
•
Multiple controllers own an analog input module. A configuration change
is required. You must make the change in the program in all controllers.
In this case, complete the following tasks.
a. Inhibit the module.
b. Change configuration in all controllers.
c. Uninhibit the module.
•
You want to upgrade the module. We recommend you complete the
following tasks.
a. Inhibit the module.
b. Perform the upgrade.
c. Uninhibit the module.
•
The program includes a module that you do not physically possess and you
do not want the controller to continually look for a module that does not
exist.
Inhibit the module until it physically resides in the proper slot.
To see where to inhibit a module connection, see
