< Peripheral (USB) port >
A direct connection can be made between
the USB port of the personal computer
and the PLC using the
commercially-available USB cable
< Serial (RS232C) port connection >
Use the serial cable
(XW2Z-200S-CV/500S-CV) to connect the
PC and serial port on the CPU Unit. (The
CPU3* does not have the RS232C port on
it. Mount the RS232C option board
(CP1W-CIF01) and connect the cable with
the unit)
