Programmable controller
1)
1) Connect the computer link connector (RS-232C/RS-422) of a programmable controller to the
communication connector (RS232C/RS422: 9-pin D-sub, female) on the controller.
See "Chapter 23 : Computer Link" in the IV-C35M User's Manual (Function and Operation).
- In the case of RS-232C, the maximum communication cable length depends on the
communication speed.
See page 5-14.
2) Connect the input/output terminals of the programmable controller to the input/output terminals
on the controller.
See page 5-12.
