Which protocal does the Omron CPM1A use?

Hi does anyone know which protocal the cpm2a plc uses? I want to interface it with the C-more micro and C-more full color screens. Also has anyone tried this if so is it fairly easy to learn this will be my first time I've tried this. Any helpful feedback would be nice thanks

Looks like you'll be using the Host Link protocol. The C-more help shows you the wiring needed to build your own cable. Looks like Omron uses pin 9 for ground instead of 5, so there's probably no standard cables that will work for you.

Another thing to watch for, you will probably need to short pins 4 and 5 on the plc end.
