I would like to build a model using image data and NI-cRIO-9063 and NI 9264 for voltage control.
for image, I made a script in python using OpenCV libraries that detecting some points . For voltage control, I use cRIO-9063 with NI 9264 voltage controller.
My question is, I am new in LabVIEW and I don't have any idea how can I make a loop for voltage control in python. Is there any library available in python that directly connect cRIO and NI 9264 devices? if not then how can I combine my image data(which is in python) with cRIO device? I need argent help.
I'm trying to read six input registers from a remote device but the software I put together doesn't seem to do much; no errors but no read-backs either. I'm a beginner, so the answer is probably simple. The remote device input registers start at 200 hex. The device uses TCP and the IP address is correct. My computer communicates well with the remote device through QmodMaster. Any help you could give would be appreciated. Thanks, Mike.

I am working on a machine vision project with LabVIEW.
The camera will locate some parts and send their coordinates via TCP/IP
and I created a client also with LabVIEW to display these coordinates here is how the communication going.
First, if the camera detects something then msg will be sent to the client to inform him.
then if msg was received correctly client responds with another msg to request the coordinates.
at last, the server sends the coordinates to the client.
here I faced some problems
1- the msg sent are with variable length ("x=0,y=0,Rz=0"==> "x=225,y=255,Rz=5" ==> "x=225,y=255,Rz=90" length vary between 16 and 22 ) with the constant "byte to read " it will not display the full msg.
2-the client works fine but at a certain time, it shows errors like ("LabVIEW: (Hex 0x80) Open connection limit exceeded";;;;;; "LabVIEW: (Hex 0x42) The network connection was closed by the peer. If you are using the Open VI Reference function on a remote VI Server connection, verify that the machine is allowed access by selecting Tools>>Options>>VI Server on the server side"
I am just starting on trying to be able to use Python code from a LabVIEW application (mostly for some image analysis stuff). This is for a large project where some programmers are more comfortable developing in Python than LabVIEW. I have not done any Python before, and their seem to be a bewildering array of options; many IDE's, Libraries, and Python-LabVIEW connectors.
So I was wondering if people who have been using Python with LabVIEW can give their experiences and describe what set of technologies they use.

I have installed Labview 2020 on Dedian Buster using the rpm to deb conversion method via alien. Due to Architecture mismatch i deleted the *i386.rpm files before conversion.
My Problem is that after creating a project at "Build Specification"-> "rigth click" i am only able to select "Source Distribution". Application does not show up as an option.
I will be grateful for any suggestions.
Thank you in advance.
