HP4140B LABVIEW DRIVER

It's better for you create one new application with the respective drivers and start from there. Testing the code takes another hrs if you don't need to make a test fixture. Now I have to make the same sensing version work with Keithley and That is something you should probbaly learn, but may be more than you wish to tackle right now.

NI provides many and vendors provide them as well. I'm relatively new in Labview. Message 8 of I now know enough to know that I have no clue about anything at all.

Attached are pictures of my code and GPIB parameters.

The other possibility that you proposed opening and closing the subVI's panel is easier? If it has, then it reports the error that you are seeing.

Labview does not labvifw neither through 0 nor through You could try increasing the timeout value used to allow the instrument more labfiew to process. You can try to specify the virtual comport as the visa resource for the instrument. Good thing you saved so much money on buying that controller.

Message 5 of 8. Message 4 of The hp410b devices, of course, will implement these functions entirely differently, but you can "hide" that level of detail within a sub-VI called "Initialize Device" that might have, as a parameter, the device you plan to use.

Most Active Software Boards: I replace it with the unlocked below.

I'm not at all lahview with that instrument and you did not attach the driver. Other ways include running the subVI in parallel and passing the data via a queue.

Most Active Software Boards: Message 7 of What does it mean when the "poll response byte" is less than zero, why is it happening intermittently, and what do I have to do to keep it from being less than zero?

About the next bp4140b you are told to add another "feature," you will wish you had taken the time now. Most Active Software Boards: Since the driver does not use VISA, you will have to completely rewrite the driver.

On the other hand it might be faster to learn that and develop a robust program than to tweak your existing program to do things it was never inteded to do.

Solved: LabVIEW does not run HPB .vis - Discussion Forums - National Instruments

I cannot run the examples in the library of the instrument. Message 6 of Do you have, Dennis, a link or path to view it? A labciew has been sent to the development team to investigate. Can you think of a way labviw coming around this? Nonetheless, now I'd need to add a way of seeing the I vs V graph or alternatively I vs time and V vs time as the program is running, not only at the end.

Just like the prologix site says, if the driver uses GPIB calls, you will have to replace all of them with serial functions. Proud to say that I've progressed beyond knowing just enough to be dangerous.

Jeff made a good explanation.
