We had just recently upgrade from Vee 8.5 to 9.3 and Windows XP to Windows 7. We had run some previous tests in the software over the past 2 weeks or so. No issues popped up. No we are running our next test and in the past 3 days the software has crashed 4 times or more.
It now gets:
Error number: 751
Exception type: System.Runtime.InteropServices.COMException
Agilent34980A: IO Error: VI ERROR_NCIC: Not the controller-in-charge.returned error code: 0x80044212
Error occurred while calling a .NET object
Erroring call was in transaction number 1
Transaction was calling Reading = agilent34980AClass.Measurement.Read(ChannelList)
Object title: Read Sensor
Object type: IVI-COM
In UserFunction: readSensor
-----------------
To me this seems to indicate that the agilent 34980A went out of remote mode. Problem is that nobody was anywhere near the front panel of the 34980A when this error pops up...
Any ideas of how to debug this issue?
Thanks,
Greg

writing and then reading back data from the instrument. It just occurs now and again out of the blue. No one touched the front panel of the instrument when it occured.
Installed on the controlling PC is Agilent Libraries Suite 17.1. The OS was Windows 7.
I suspect it is a timing issue between the write and then the instrument not being prepared for the subsequent read - I will investigate.
Did the poster of the original comment resolve in any way that could be shared here?
