Norma 4000 Data Acquisition

[andreab93]

Hi everybody,

I'm trying to acquire current and voltage data from a Fluke Norma 4000. I'm using  RS232 with factory configurations , 115200 8/N/1 Hardware. I'm using the LNAOPA01 library which is provided by the manufacturer.
I get this error and I can' t find anything about it:

Error -1073807345 occurred at Property Node (arg 2) in VISA Configure Serial Port (Instr).vi
Possible reason(s):
VISA: (Hex 0xBFFF000F) Specified type of lock cannot be obtained, or specified operation cannot be performed, because the resource is locked.

Does anybody ever dealt with this problem?
I add my VI below.

Thanks in advance for any advice,
Andrea.

I also tried to substitute  "Visa configure serial port" with "LNOAP01 Initialize.vi" provided in the isntrument library and now i get this kind of error:

Error -1073807343 occurred at Property Node (arg 1) in LNOPA01 Initialize.vi->LNOPA01 Getting Started.vi

Possible reason(s):

VISA: (Hex 0xBFFF0011) Insufficient location information or the device or resource is not present in the system.

did you have max or another program open when you tried your program.

It looks like a struggle from 2 places for the com port.

I also saw another driver on the NI instrument driver website. Try that one.

Thank you Albert for your reply.

I'm paying attention not to open other programs that may be working on the com port. Max and the specific program of the isntrument are closed.

I tried with the driver on NI website, but Labview keeps  showing me this error:

VISA:  (Hex 0xBFFF0011) Insufficient location information or the device or resource is not present in the system.

I tried to communicate with MAX and it works. The problem seems to come out only on my VI.

Let's shake the magic 8 ball here and test its calibration (It has a fairly good history of finding answers)

~~~Oh, Magic 8-Ball!  Does andreab93 stop the vi with the Abort button?~~~

Answer: Undoubtably!

When you hit that ribbon bar Stop glyph the vi quits immediatly leaving the instrument session open.  Hence, when you try to open a new session there is an existing lock!  DON'T do that!  MAX, on the other hand, politely closes the session to the device so, MAX works and your vi doesn't

Thank you Jeff.

I can't still read values from the instrument, but the error doesn't pop up now.

OK, Now that we are this far let's see some code and fix the communication protocol.

I attach my VI.
