Spudnick 0 Posted January 30, 2015 (edited) Hey, I'm working with an Aligent Oscilloscope. Now I wanted to control it from my PC via Autoit and I found out, that the Visa.au3 is alredy included. But the help is just something about GPIB and TCP/IP. I already foud out about the adress of my device: USB0::0x0957::0x0588::cn49302469::0::INSTR Using the Software "Agilent IO Control" it is possible to control the device with the build in "Interactive IO" I tried to use the code given by the example, but it dosn't connect #include <Visa.au3> MsgBox(0, "Step 1", "Open the instrument connection with _viOpen") Local $h_instr = _viOpen("USB0::0x0957::0x0588::cn49302469::0::INSTR") MsgBox(0, "Instrument Handle obtained", "$h_instr = " & $h_instr) ; Show the Session Handle ; Query the instrument MsgBox(0, "Step 2", "Query the instrument using the VISA instrument handle") Local $s_answer = _viExecCommand($h_instr, "*IDN?") ; $h_instr is NOT A STRING now! MsgBox(0, "GPIB QUERY result", $s_answer) ; Show the answer ; Query again. There is no need to OPEN the link again Does anybody know how to make it working self-sufficient with autoit Edited January 30, 2015 by Spudnick Hide Spudnick's signature Hide all signatures Who needs USA... we already got USB :shifty: Share this post Link to post Share on other sites
jchd 1,240 Posted January 31, 2015 Can't answer your precise question. All I had working some time ago was using National Instrument software and device drivers to manage a GPIB-ENET network (VISA interface). I have zero experience with Agilent software but normally VISA is build for abstracting the connection layer. Are you sure you don't miss a driver layer in your setup?

Spudnick 0 Posted February 2, 2015 I think if there is a driver missing it's missing in my script, because with the original program is working fine. Is that what you mean? Untill now i wasn't able to get a working connection. If the oscilloscope is getting any order by USB it is changeing to the remote mode, but it still doesn't if I run my script. Does it make a difference if I am working on a 64 or a 32 bit system? So I have a 64 bit win7 PC. I already changed the .dll in the Visa.au3 from visa32.dll to visa64.dll. I have verified that both are there in the system32 Folder. With the "32.dll i get the errorcode -2. With the "64.dll i get a -1 error.

jchd 1,240 Posted February 2, 2015 I'm afraid that my poor experience isn't helpful in your case. When compiling for 32-bit then use the 32-bit dll in system32. That should be working since drivers are available. Sorry I can't give you useful advice here.

jchd 1,240 Posted August 19 Oh yes, you need to load the DLL before use. I missed that obvious point in your sample code.
