Module Inhibiting

With module inhibiting, you can indefinitely suspend a connection between an
owner-controller and a module. This process can occur in the following way:

You write configuration for a module but inhibit the module to prevent
it from communicating with the owner-controller. In this case, the
owner-controller does not establish a connection and configuration is
not sent to the module until the connection is uninhibited.

The following examples are instances where you may need to use module
inhibiting:

You want to FLASH upgrade your module. We recommend you:
a. Inhibit the module.
b. Perform the upgrade.
c. Uninhibit the module.

You are using a program that includes a module that you do not
physically possess yet, but you do not want the controller to continually
look for a module that does not exist yet. In this case, you can inhibit the
module in your program until it physically resides on the network.

Disable Keying

The inserted module attempts to accept a connection to the controller regardless of its type.

ATTENTION

Be extremely cautious when using the disable keying option; if used incorrectly, this
option can lead to personal injury or death, property damage or economic loss.

If keying is disabled, a controller makes a connection with most modules of the same type as that used in the
configuration.

A controller will NOT establish a connection if any of the following conditions exist, even if keying is disabled:

The module is configured for one module type (for example, input module) and a module of another type (for
example, output module) is used.

The module cannot accept some portion of the configuration. For example, if a non-diagnostic input module
is configured for a diagnostic input module, the controller cannot make a connection because the module will
not accept/process the diagnostic configuration.
