64 Module Diagnostics and Troubleshooting
Module Inhibit Function CompactLogix controllers support the module inhibit function. See your
controller manual for details.
Whenever the 1769-BOOLEAN module is inhibited, the module's output
state enters either the program state or the off state and the module's outputs
are changed accordingly. The output state entered by the module depends on
whether the CompactLogix controller supports alternate output states (refer to
your controller manual to determine if alternate output states are supported).
CompactLogix controllers that support alternate output states cause the
module's outputs to the program state; controllers that do not support
alternate output states cause the module's outputs to the off state.
When the 1769-BOOLEAN module is inhibited, the module continues to
provide information about changes at its inputs to the CompactLogix
controller.
Contacting Rockwell
Automation If you need to contact Rockwell Automation for assistance, please have a clear
statement of the problem, including a description of what the system is
actually doing, available when you call. Create a list of the following:
• LED states
• Input and output image words for the module
• Remedies you have already tried
• Controller type and firmware number (see the label on the controller)
• Hardware types in the system, including all I/O modules
• Fault code, if the controller is faulted
