void (_stdcall *StationsApply)(HOBJ LnID, unsigned int Prot, void *AplPar);

LnIDLine ID. A series of callings the interface function StationsApplyBack will be generated for all stations of the line.
ProtRequired protocol. All stations must contain the protocol in order to meet calling the function StationsApplyBack (constants OEM_Prot1 up to OEM_Prot16).
AplParPointer that is passed into calling the function StationsApplyBack.

After calling the function StationsApply, the process D2000 KOM calls the interface function StationsApplyBack for all stations of a line with called ID and given protocol and gives the parameter AplPar. The function mostly eliminates a necessity to keep own lists of stations.
