Hi,

i have difficulty to make a CJ1M cpu11 communicate with a touch screen NT31.

the plc port is set : host link 

in the TS menu i cannot change the comm A method to host link ( invalid comm method) . i tried with the port B (RS-232C)

the cable is 25 pin (NT) and 9pin (PLC) with RTS-CTS shunted

2-3 

3-2

7-9

Please help me.

Thank you.

I'm not sure of a solution at the moment but if you want to try Com A, set Com B to 'None'. Then you should be able to set Com A to Host Link.

Attached is the correct pin out for the cable.

Make sure the CJ1M Serial Port is set for Host Link and the correct communication parameters.

Hope this will help.

What is the PT Control Area set to?  This area controls what screen you are on.
