Chapter 2
Module Inhibiting
Module inhibiting lets you indefinitely suspend a connection, including Listen
Only connections, between an owner-controller and an I/O module without
removing the module from the configuration. This process lets you temporarily
disable a module, such as to perform maintenance.
You can use module inhibiting in the following ways:
• You write a configuration for an I/O module but inhibit the module to
help prevent it from communicating with the owner-controller. The
owner does not establish a connection and the configuration is not sent
to the module until the connection is uninhibited.
• In your application, a controller already owns a module, has downloaded
the configuration to the module, and is exchanging data over the
connection between the devices.
In this case, you can inhibit the module and the connection to the
module does not exist.
You can use module inhibiting in the following instances:
• You want to update an I/O module, for example, update the module
firmware revision. Use this procedure.
a. Inhibit the module.
b. Perform the update.
c. Uninhibit the module.
• You use a program that includes a module that you do not physically
possess yet. You do not want the controller to look for a module that
does not yet exist. In this case, you can inhibit the module in your
program until it physically resides in the proper slot.
You can inhibit the connection to a Compact 5000 I/O digital module on the
Connection category of the Module Properties dialog box.
To see where to inhibit a connection, see the following:

IMPORTANT
You cannot inhibit a connection when the controller is safety-locked or a
safety signature exists for the controller.
IMPORTANT
Whenever you inhibit an output module that is ProgMode enabled,
it enters Program mode, and all outputs change to the state
configured for Program mode.
For example, if an output module is configured so that the state of
the outputs transition to zero during Program mode, whenever that
module is inhibited, outputs transition to zero.
