Hi Abdalla,

You should capture the communications stream between the IOC and the controller using asynTrace.  Type the following commands at the IOC prompt or put them in your startup script.  Replace PORT with the name of the drvAsynIPPort.

asynSetTraceIOMask PORT 0 2

asynSetTraceMask PORT 0 9

If it takes a long time to fail then you might want to send the output to a file

asynSetTraceFile PORT 0 filename

That trace should tell you if there was some miscommunication before the pressure PV comes back wrong.

Mark

Subject: StreamDevice with Telnet port

Hi

We have the Gamma QPC ion-pump controllers controlled via StreamDevice through telnet, port 23. We have 4 parameters implemented, pressure, voltage, current, and channel status. The problem is that the IOC gives an error that the value received for the pressure PV is "Running", i.e. "Input Running does not match format %E". Seems like at some point the controller is not finishing a previous parameter and the IOC receives something different than the current parameter requested.

We have the following in the protocol file:

OutTerminator = CR;

InTerminator = CR;

ReadTimeout = 2000;

ReplyTimeout = 2000;

And each parameter in the protocol file has ExtraInput = Ignore at the end. Any help resolving this mismatching issue?

Best Regards,

Abdalla Ahmad
