GPIB Controller "sre 0"

[JohnBoy]

I have a LabVIEW 7.1 application that interfaces via GPIB (488-2) with a Ruska 6005 Interface Panel.  For the most part, there are no problems. However the author has used "sre 0" at the end of the program to unassert REN and return the interface to operator control, but the interface stays in Computer mode and is still not available for manual operations.  Can anyone suggest why?

Hi John,

I didn't see that NI has an Instrument driver for Ruska 6009 available on the website.

Where did you get this instrument driver from?

The driver for this application was developed in-house, because no off-the-shelf driver was available.

Hi John,

Are you using VISA API or 488.2 API?

Would you be able to post a screenshot of that part of code?

Have you tried writing a simple peace of code to see if this feature will work at all or not?

Please look at this link.

Does this look familiar?

Regards,

Sammy Z.

Hi Sammy, I've tried your suggestion, and it appears to fix the problem (using VISA GPIB Control REN with Mode 2). Since the problem was intermittant, I'll have to do further testing to be sure this is the fix, but it's certainly looking good. Thanks very much.

Hi Sammy, The suggested fix has worked well, including on the executable. Thanks for your help.  JohnBoy.
