Hi,
We are trying to use the PLCHandler to read values from the PLC. The host application is written in Delphi and we use the C-interface of the DLL.
In the supplied h-file (PLCHandlerItf.h) there are two callback functions defined (PLCHANDLERSCANNETWORKCALLBACK and PLCHANDLERBACKUPRESTORERESULTCALLBACK). There are no callbacks functions defined for the data change and state change callbacks though. I have tried using these callbacks without success. Are these callback functions not supported using the C-interface? If it is, how shall the callback functions be declared and used?
I do get the ScanNetwork callback working but as mentioned, not the state change or data change callbacks.
