2.18.2 Cable Diagrams

The cable diagrams illustrated below and the cable diagrams recommended by
Keyence may differ, however, using these cables for your PLC operations will not
cause any problems.

• Connect the FG line of the Shield cable to the GP.

• For the RS-232C connection, use a cable length less than 15m.
• If a communications cable is used, it must be connected to the SG
(signal ground).
• For the RS-422 connection, refer to Keyence's PLC manual for the
cable length.
