Module Inhibiting
Module inhibiting lets you indefinitely suspend a connection between an
owner-controller and a serial 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 these instances:
• You want to update a serial I/O module, for example, update the module
firmware revision. Use the following 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.
