Protected Operations

If one of the module I/O connections is open and running, it is considered as the module is in Protection Mode. Protection Mode is a state where the device is operational but has implemented defenses against disruptive changes that could take the product out of service. The following operations are restricted when the module is in Protection Mode:

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 module is in Protection Mode but as a consequence, the I/O connections are closed and reopened:

Change Electronic Keying
Change RPI
Change Unicast/Multicast

I/O channel configuration change is allowed when the module is in Protection Mode. To apply configuration change without interrupting the I/O connections, there are two methods:

Change configurations and apply in Module Properties
Change configuration tag values and send a Reconfigure Module MSG to the module to apply the changes.
