I have OMRON SRM1 CO2-V2 PLC, whenever I try to conect it with CX- programmer via RS 232C, I got (Failed to connect to PLC) message

When I changed the PLC, I can get just two option to network types (toolbus, and sysmac Way).

My RS 232 card work well, i tested it via (Putty).

what I miss here to configure ?

2- The cpu is in RUN mode, is this effect on the communication toll or not

Toolbus is the programming port.  That's how I program these devices, not via the RS232.

Omron RS-232 port pin arrangement is different from the usual computer RS-232 port.
Make sure you wired it right like shown below (right is Omron side connector, left is computer side connector) :

Thank you for replay, let me re write what I understand from your post

1- The wiring must be changed to your diagram

to be able upload the ladder diagram from my SRM 1 PLC

Now, what about the network type, which one I must use (SYSMAC WAY OR TOOLBUS)

 

[innoaloe]

Yes. And I believe both will work.
