PROGRAM PLC_PRG
VAR
uiState: INT;
usiOutput : USINT;
usiMask : USINT;
usiInput : USINT;
dwResult_out : DWORD;
dwResult_in : DWORD;
END_VAR
PLC_PRG (body)
IF uiState = 0 THEN
uiState := 1;
// GENDO output
usiOutput := 1;
usiMask := 1;
dwResult_out := GendoControlN(usiOutput, usiMask);
// GENDI input
dwResult_in := GetGendiN(ADR(usiInput));
