HTBasic hanging while doing a GPIB command, Called from TestStand

[Andrewbft]

I have functions in HTBasic called from TestStand for doing GPIB communications for different test sets. When i run the main sequence, the sequence hangs in a HTBasic step. The step is different every time. Does anybody know about this problem?

Hi,

I have some questions.

Does the HTBasic programs run by themselves?. Or does it only hang when executed in TestStand?.

What GPIB driver and interface are you using?. What GPIB operations are you performing?. Is there any error message shown?.

The main idea is to figure out if the error is caused by the GPIB operation or by TestStand.

Include any information you may consider important.

The HTBasic code works on its own. It only hangs when i run it in teststand. PCI-GPIB (NI) and 488.2. It is simply output and enter commands across the GPIB bus. No there is no error message shown from Teststand or from NI Spy

Hi,

I don't have to much experience with the HTBasic module in TestStand. I have more experience with GPIB programming, which is why I ask those questions.

i would suggest re-posting the question in the TestStand forum, so that it shows up as unanwsered, but make sure to include that the HTBasic GPIB code runs correctly by itself and that NISpy does not show any GPIB errors.
