Hi
I want to use Delphi to write a program to read/write to a plc (koyo).
The problem is i'm not sure if i'm on the right track (newbie to PLC stuff).
I want to use ethernet as the communication medium
and the protocol is i think modbus, I've read that i must get an Dll or ActiveX to handel to communication between the PC and PLC, is this right ? Is the protocol delt with in the Dll/ActiveX? Where can i get a dll or ActiveX that is not a demo/trail that will work with Delphi and the plc (koyo).
Am i on the right track when looking at my Qs?
Any help will be greatly appreciate.
Regards
Frans
