Use the Mode Switch to Change the Operation Mode
Use the mode switch to change the operation mode. The controller mode switch
provides a mechanical means to enhance controller and control system security.
You must physically move the mode switch on the controller to change its
operating mode from RUN, to REM, or to PROG. When the mode switch on
the controller is set to RUN mode, features like online editing, program
downloads, and firmware upgrades are prohibited. See
Table 5 for a complete list
of prohibited features.
The physical mode switch can complement other authorization and
authentication methods that similarly control user-access to the controller, such
as the following:
• Logix CPU Security tool
• FactoryTalk Security service
