Controller
The 1756-L6x ControlLogix controller uses a serial port for workstation
connections.
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, the
controller door may not close)
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 both connectors.
WARNING: If you connect or disconnect the serial cable with power applied to
this module or the serial device on the other end of the cable, an electrical arc
can occur. This could cause an explosion in hazardous location installations.
Be sure that power is removed or the area is nonhazardous before proceeding.
