Wiring for a Memory Link Connection

Cables with connectors that can be used at serial port A:

XW2Z-200T (9-pin ⇔ 9-pin, 2 m)

XW2Z-500T (9-pin ⇔ 9-pin, 5 m)

CPU Units of CVM1/CV-series PLCs without the suffix -EV@cannot be con- nected by any connection method.

When connecting to the peripheral port of a CS/CJ-series CPU Unit, a CS1W- CN118 Connecting Cable is required in addition to the above cables.

Serial Port A, B
