VAR
MyLocalIOStatus : LOCAL_IO_GEN_STATUS;
END_VAR

MyLocalIOStatus := GetLocalIOStatus(LOCAL_IO_GET_GEN_STATUS);

This example shows the use of an intermediate variable for Mode input parameter.

VAR
    MyLocalIOStatus : LOCAL_IO_GEN_STATUS;
    MyMode : LOCAL_IO_GET_STATUS;
END_VAR

MyMode := LOCAL_IO_GET_GEN_STATUS;
MyLocalIOStatus := GetLocalIOStatus(MyMode);
