What does the xantrex driver error 5 mean and how to solve it?

[oy9898]

Dear Experts,

I downloaded a new XANTREX driver and used it to control our new XHR 150-7 power supply. I tried to use the GET STRAT.vi to control the output of the power supply. The output could be controlled according to the command input. However, there is always an ERROR 5 message poped out whenever it ran. The error source seemed to be in the DELAY & READ.vi.

I would be most grateful if you could tell me how solve this problem at your earliest convenience.

Thanks a lot for your attention and help,


James

Exactly which driver did you downlaod and from where? By "GET STRAT", do you mean one of the Getting Started VIs? Error 5 means "NI-488:  Command requires GPIB Controller to be System Controller." Are you using GPIB to control the instrument? If so, what type of board are you using and which version of VISA and NI-488? If the error only occurs on a read, try issuing the query from MAX and see if the error occurs there. In a couple of the Xantrex drivers I looked at, there seemed to be some fixed delays after a write and before a read. You might try increasing those values to see if that makes any difference.
