To connect a workstation to the serial port, you can make your own serial cable or use one of these cables: • 1756-CP3 serial cable • 1747-CP3 cable from the SLC™ product family (if you use this cable, it can be difficult to close the controller door)Follow these guidelines if you make your own serial cable: • Limit the length to 15.2 m (50 ft). • Wire the connectors as shown. • Attach the shield to the connectors.
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
