Hello All.

I have no experience with Omron PLC and I am asked to find the problem in the working system. I have:

PLC – SYSMAC CQ1 CPU45-V1;

Soft - CX-PROGRAMMER 3.0;

HMI – NT600S (connected to PLC by the RS-232C method)

Soft – NT Support (can’t remember exact ver.)

I have uploaded the PLC program to CX-PROGRAMMER.

My problem is: - I couldn’t get on-line to NT600S.

Is it possible communication: PC (NT Support) -> CQ1 CPU45 - > NT600S?

Also I tried: PC (NT Support) -> NT600S? Unsuccessfully, may be wrong cable. Tomorrow I will try existing cable that connects CQ1 CPU45 - > NT600S.

I will be highly appreciated for any consideration
 
I think you can set the comms path to go though the processor, has been a while since I have done it, but from memory the function is there.

Just had a quick look, doesn't look like you can go through the NT support tool, you can with NS-Designer, or the new CX_designer.

The cable should be the same as the one you used to upload the PLC file.
With the NT screens however, you have to enable connection. I cannot find the manual on this procedure, but you press 2 corners of the NT screen, and then follow the menu system to enable transfer.

Hope this helps
 
Use this cable to connect PC (NT Support Tool) to NT600S.

Thanks a lot. I was away from my computer over weekend. “Pressing 2 corners” it is the news for me, think it will help. I have already made the cable; wiring taken from OMRON web site. It is the same as IO_Rack said except last two missing conductors. I’ll try tomorrow.
 
Thanks everybody. It works. I pressed two corners and went to transfer mode. After that successfully uploaded the HMI NT600S.
