2.3.6 Wiring for PIO
The connection of I/O to the controller is to be carried out using the dedicated I/O cable. The
cable length is shown in the model code of the controller. Please check the controller model
code. There are 2m for standard, 3m and 5m as an option. Up to 10m can be enabled sold
separately. [Refer to “1.1.5 How to Read the Model”]
Also, the end of the cable harness to be connected to the host controller (PLC, etc.) is just cut
and no treatment is conducted so the wiring layout can be performed freely.
