[LVTN] Messenger Library

[bbean]

Hi @drjdpowell,

Before I reinvent the wheel, do you have any examples of python modules sending messages to one of your LabVIEW TCP Event Messenger Servers (or a simple UDP Receiver / Sender pair)?

I'm interested in extending an existing LabVIEW Messenger Actor to guys on the python side as an API.  I'm not sure the best way for them to send message, but a simple one would be to simply send a string with the format (Message Label>>Msg Param1, Msg Param2....)

I'm afraid I don't have an example.  I did once prototype a version where I swapped out the flattened message format for one that used JSON (I recommend JSON as an easy, reliable format to go between languages).

Take a look here: https://github.com/VITechnologies/RemoteLabVIEWInterface

It works great! It uses JSON to pack up stuff from python and send over ZeroMQ.

Hello, when trying to install version 2.0.8.152 for LabVIEW 2023 Q1 (64-bit) I am getting the following error:

Could it be the 64-bit LabVIEW?

That vipm package seems to have gotten corrupted somehow.  I'll contact NI about it.  In the meantime, try getting it from here: https://forums.ni.com/t5/JDP-Science-Tools/Out-of-Memory-Error/m-p/4335019/highlight/true#M156
