Protected Operations

To maintain the secure operation of your I/O module, operations that can disrupt module operation are restricted based on the module operating mode.

In Protection Mode, the device deactivates services that could disrupt the operation of the device, but the device continues to function. For example, configuration operations or firmware updates are disabled to not impact the operation of the device.

The module enters Implicit Protection Mode as soon as an I/O connection is established to the module. The module exits Implicit Protection Mode as soon as all I/O connections to the module are stopped.

When the device is in Implicit Protection Mode, the mode prevents the following actions:

Firmware update request
Module reset request
Connection or data format change

The following operations can be applied in Studio 5000 Logix Designer application when the modules are in Protection Mode, but as a consequence, the I/O connections are closed and reopened:

Change Electronic Keying
Change RPI
Change Unicast/Multicast

The following operations are allowed when the modules are in Protection Mode:

Listen-only connection requests from other controllers
I/O channel configuration change. To apply configuration change without interrupting the I/O connections, there are two methods:
Change configurations and apply the changes in the Module Properties dialog.
Change configuration tag values and send a Reconfigure Module MSG to the module to apply the changes.
