I have been learning (slowly) to get a set of external instuments connected to LabView. For the most part, I have been succesful reading and writing commands and data from basic instruments. There is a problem that I cannot figure out with both of my Agilent 6653A power supplies.
I can get the supplies to turn output on/off as well as adjust volts/amps. The problem is trying to read measured volts and amps back. The VI freezes and offers an error message that I do not understand. Here are some screen shots, if it is helpful to upload the VI's, of course I can do that.
This is a test VI that only function is to have basic control of the power supply and a Keithley DMM to do a comparison read. Both work just fine until I add the READ MEAS vi on the power supply section of the block diagram. It seemed simple, pass the VISA and ERROR through and it should spit out the voltage and current as a DBL.
I manually tested the commands and the returned data looked ok.
FIRST ERROR........
SECOND ERROR......This one is related the Keithley DMM
Not sure where to look for an answer. Hoping there is a simple answer.
Thanks in advance to anyone willing to take the time to help.
