Connecting CX_Programmer to CP1E using RS-232 to RS-232

[MStewart 0]

Hey everyone,

I am brand new to this forum as well as OMRON. I am trying to connect to my CP1E-NA20DT-D using the RS-232 port on my PLC to my RS-232 port on my laptop.

When I try to connect it is telling me "Failed to connect to the PLC". Is it possible to go RS-232 to RS-232? I am trying to use COM5 (Communication Port) but I have also tried COM3 with no success.

I have tried using CX-Network Configuration Tool to find my PLC but still again with no luck.

Any help would be greatly appreciated!!

Thanks McKenzie

How is the cable made? It is not a standard pinout.

Thanks for the quick reply and that would be my problem then.

I am going to have to get a proper cable.

Thanks!

I have found a USB-A to USB-B cable so I am now playing around with that but I am still getting a failed to connect to plc message. I have checked my device manager and under other devices tab it does say OMRON-PLC.
Any suggestions?
Thanks McKenzie

Use auto connect and select USB - it will do it for you.

Hi

Can u send me sample of analog programme

Analog signals enter the PLC as an integer value.  The range depends on the input module and settings.
