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 updates are prohibited. See Table 7 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
Dependent on the mode of the controller you specify by using the mode switch, you can change the Operation mode of the controller in the Logix Designer application. After you are online with the controller and the controller mode switch is set to Remote (REM or the center position), you can use the Controller Status menu in the upper-left corner of the application window to specify these operation modes: • Remote Program • Remote Run • Remote Test
