Hi. I work for an industrial machinery merchant so we have to try to get uploads from all sorts of different PLCs & HMIs.
Our latest victim is an Omron CQM1H-CPU21, see attached photo. It is successfully communicating with an HMI via the DE-9 9-pin connector to the HMI's RS232 port. So I'm trying to use the DE-9 for the upload - we don't have any cables that mate with the other connector in the photo. We have a few Omron cables but none of them seem to be the right one for this. I tried both an Allen-Bradley 1747-CP3 and a 2711-NC13 cable. One of the cables, connected in one direction seemed to get a little further but ultimately failed to connect. I'm using the CX Programmer software.
Can anyone offer any insight as to which cable I need and whether CX Programmer is the correct software, please?
