Start to Use the Controller Chapter 3
Use the Mode Switch to Change the Operating Mode
To change the operating mode, use the mode switch. 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 6 for a complete list of prohibited features.
The mode switch can complement other authorization and authentication
methods that similarly control user-access to the controller, such as the
FactoryTalk® Security service.
The mode switch on the front of the controller can be used to change the
controller to one of the following modes:
• Run (RUN)
• Remote (REM)
• Program (PROG)
IMPORTANT During runtime, we recommend that you place the controller mode switch in
RUN mode. This practice can discourage unauthorized access to the
controller or potential tampering with the controller program,
configuration, or device firmware.
Place the mode switch in REM or PROG mode during controller
commissioning and maintenance and whenever temporary access is
necessary to change the program, configuration, or firmware of the product.
