For PC connected to OMRON PLC:
You need to learn/read OMRON HostLink Communication manual. For example if you send form VB (via COM1) string:
"@00RD0000..", and then rad data in VB form COM1, You will get an answer (string also) form PLC. I Tried it and it worked fine.
For E5* regulators, and inverters, You can find a proper Communication manual with DETAILED (usefull) instructions.
