I want to do with AB (PLC) communication with DELPHI, use AB RSLink API (DTL_DRIVER_OPEN DTL_C_DEFINE,,), but the szDriverName don't know the format, how also can't connect, could you tell me how to use player?

CodePudding user response:

Al RSLink can use OPC, many years ago, I used a variable's value can be read directly in the PLC, now forget, ha ha
