Inhibit a module
To make it easier to test a system one module
or section at a time:
1. Initially, inhibit all the modules.
2. To test a section of the system, clear the
check boxes for the modules of that section
(i.e., uninhibit the modules).
If communication with a modules fails, the
controller operates on old data from the
module. To avoid potential injury or damage,
either monitor communications with modules
or configure modules to produce a major fault
if communications fail.
Then:
Select the check box.
Leave the check box
cleared (unchecked).
