Hi,

This can be done by defining the parameter like this:

<Param id="2000">
<Name>Adres TempW2</Name>
<Description>Adres of TempW2</Description>
<Type>read</Type>
<Interprete>
<RawType>unsigned number</RawType>
<LengthType>fixed</LengthType>
<Length>2</Length>
<Type>double</Type>
</Interprete>
</Param>

In the QAction this can then be filled in like this:

int adresValue = 268;
protocol.SetParameter(2000, adresValue);

In the StreamViewer the communication will then look like this:

<< 08:01:52 - Send Command
000000 0C01

As you can see this is probably not as expected, as decimal value 268 is 0x010C and the StreamViewer is showing the bytes reversed. This is because by default little endian is used. So the little end (least significant byte) is sent first followed by the more significant.

How can this behavior be changed? This can be done by changing the endian to big (send big end (=most significant byte) first) and can be done in the interprete:

<Interprete>
<RawType>unsigned number</RawType>
<LengthType>fixed</LengthType>
<Length>2</Length>
<Type>double</Type>
<Endian>big</Endian>
</Interprete>

The StreamViewer will then look like this, which is more like expected:

<< 08:02:17 - Send Command
000000 010C
