[Development] QtSerialBus : Function Code 20 and 21 not implemented

[Karsten Heimrich]

Hi Vincent,

we just didn't manage to implement all functionallity provided by the specification. Right now there is no pending patch or implementation I know of, but we are definitifly looking into finishing it for a later release. Of course, if you need the functionality you can implement it on your own by inheriting from one of the QModbusServer descendants. We are also open for patches that provide the missing implementation.

Obviously you found the issue on jira already: https://bugreports.qt.io/browse/QTBUG-49510?filter=17150

Subject: [Development] QtSerialBus : Function Code 20 and 21 not implemented

Hi everyone,

I try to use the new QtSerialBus with the Qt 5.7.0, and during my test, the Function Code 20 and 21 answer Illegal Function.

When I opened source code, I saw this :

Line 662, File qmodbusserver.cpp :
    case QModbusRequest::ReadFileRecord:    // TODO: Implement.
    case QModbusRequest::WriteFileRecord:   // TODO: Implement.
        return QModbusExceptionResponse(request.functionCode(),
            QModbusExceptionResponse::IllegalFunction);

My questions are :

Why the documentation do not precise that this Function Code is not implemented ?
And
Is there a plan to finish this implementation in the next release ? or is someone have a kind of begining of source code or patch ?

Best regards,

Vincent SENECLAUZE
