USING System.Serialization;

FUNCTION SerDe_Demo
    VAR_TEMP
        t : ARRAY[0..1] OF BYTE;
        roundtrippedINT : INT;
    END_VAR

    Serialize(UINT#0, UINT#16#1234, t);
    Deserialize(UINT#0, t, roundtrippedINT);
END_FUNCTION

Note

By default, the Serialize and Deserialize functions use little endianness. The endianness can be specified/changed by passing an additional argument to the Serialize and Deserialize functions or by using the SerializeLittle/DeserializeLittle or SerializeBig/DeserializeBig functions, respectively.
Index of parameter buffer array should start from 0, like ARRAY[0..7] OF BYTE.

USING System.Serialization;

FUNCTION SerDe_Demo
    VAR_TEMP
        t : ARRAY[0..1] OF BYTE;
        roundtrippedINT : INT;
    END_VAR

    // serialization/deserialization using big endianness:
    Serialize(UINT#0, UINT#16#1234, t, Endianness#Big);
    Deserialize(UINT#0, t, roundtrippedINT, Endianness#Big);

    // alternative for serialization/deserialization using big endianness:
    SerializeBig(UINT#0, UINT#16#1234, t);
    DeserializeBig(UINT#0, t, roundtrippedINT);

    // use INT offset
    SerializeBig(0, UINT#16#1234, t);
    DeserializeBig(0, t, roundtrippedINT);
END_FUNCTION
