I have a very big issue using Measurement Studio 2013 and Network Variables. Let me give you the setup first.
One of our products includes a cRIO/sbRIO that uses published network variables that can be read/written to to change settings or gather data. They're simple string/int32/doubles for the most part. We also use a frontend built in .NET 4 using Visual Studio 2010 with a few references to National Instruments DLL's, including the network variable assembly.
Just a few days ago, I uninstalled all my NI software and reinstalled from the 2013 DS2 disk in order to get LabView up to 2013. What a mistake that was. After updating all the references in the VS2010 project and setup project, rebuilding the setup and deploying it on to a product PC (which does not have NI software installed), I now suddenly cannot read or write to any network variables on the cRIO. The error I continuously get (after modifying some code to spit the error out) is:
"The network variable process was not found or is not responding"
I have not changed any of the backend code, which is pretty much made up of the following:
public cNetworkVariableString(string name, string location, double timeOut)
{
_timeOut = TimeSpan.FromSeconds(timeOut);
_location = location;
_name = name;
try
{
_reader = new NetworkVariableReader<string>(_location);
_writer = new NetworkVariableWriter<string>(_location);
_writer.Connect(_timeOut);
_reader.Disconnect();
_writer.Disconnect();
_error = false;
}
catch (Exception ex)
{
_error = true;
_errorMessage = ex.Message;
}
}
Anyone have any idea what could be the problem? FWIW, I kind of took over the role of programmer in the past year, so a lot of this is new to me and I'm hoping I'm simply overlooking something simple.
Thanks,
Mike
