Hi

I have a python TCP server which waits and receives a data packet (e.g., "DEVICE1" string) from a socket (e.g. on port 3333) and then it writes back the "text1." string to the socket.

I developed a serial over TCP xml protocol driver in dataminer and seems the driver is working.

I can see the protocol driver can send "DEVICE1" string packet to my python TCP server and I can see the protocol driver can receive "text1." data from the python server (from the element Stream Viewer).

=============================================

<< 05:35:27 - getTCPdata
000000 4445564943 4531 DEVICE1
>> 05:35:29 - getTCPdata
000000 7465787431 2E text1.

==============================================

I have a parameter (parameter 7) in the xml protocol trying to show the content of the received data ("text1.").

But looks like the parameter could not decode the data ("text1.") sent from the python server. The parameter content in the element page is empty.

Therefore, how to decode the data ("text1.") in dataminer xml protocol side?

Following is my python code which sends string 'text1.' which is encoded to utf-8:

connection.sendall("text1.".encode('utf-8'))

Following is the parameter 7 xml tags:

<Param id="7" trending="false">
<Name>Returned Str</Name>
<Description>Returned Str</Description>
<Information>
<Includes>
<Include>range</Include>
<Include>units</Include>
<Include>steps</Include>
<Include>time</Include>
</Includes>
</Information>
<Type>read</Type>
<Interprete>
<RawType>other</RawType>
<LengthType>next param</LengthType>
<Type>string</Type>
</Interprete>
<Display>
<RTDisplay>true</RTDisplay>
<Positions>
<Position>
<Page>General</Page>
<Column>0</Column>
<Row>2</Row>
</Position>
</Positions>
</Display>
<Measurement>
<Type>string</Type>
</Measurement>
</Param>
</Params>

Thanks
