Is it possible to use TestScript as a type of test sequencer in LabVIEW where the UI can display the 'script', which would be python code, and be able to run in single step mode or at least be able to highlight the current python line being executed.

Nicely described approach Shaun. I am doing something similar with a lab automation project that involves vacuum chamber and multi-zone temperature control. Elected to use the messenger framework, which supports 'spinning up' instances and TCP capability for remote devices like cRIO. The messenger architecture also supports many types of asynchronous messaging beyond simple synchronous command/response. Your idea of decoupling EC sequencing logic is good, moving it out of the EC subsystem to allow synchronization with other subsystems during ramp/soak profiles. Hey remember Test Stand Lite? This is where an such a scripting component would really shine and be a great benefit to the community.

I wonder, would it be possible to use your SQLite Logger to extend the messenger library to have a logging capability similar to the Worker Framework Message logs. https://docs.workersforlabview.io/workers-tools/workers-tools-menu/workers-debug-server/worker-message-logs

Apologies for the bad example. GrokAI emphasized the importance of closing .net references which I blatently disregarded

Asked GrokAI and got a working example...

Hi Yair - Would you mind sharing some example code to grab an image using the Pylon .net interface?

Or this...

A customer asked me to create a powerpoint explaining the advantages of LabVIEW. While putting together the practical rationales, just for grins I asked Chatgpt to create a presentation explaining the philosophy of LabVIEW in a Zen sort of way. Here is what it came up with. Zen_of_LabVIEW.pdf

The Gpower IOLink toolkit looks great but the cost is prohibitive. For $1000 I was inclined to give it a go but I would never saddle up to such a cost on a subscription basis and as you said they are also requiring a annual runtime license. What a disaster that would be for any of my customers when their critical systems stop working on Jan 1st. until they pony up their subscription fees. I think like you I will just dip my toes in the RESTful JSON waters and then see what it will take to generalize it.

Now that we are NI/Emerson I would expect to see more connectivity in the automation sector. It seems that IOLink is a dominate communications standard that would be a good candidate for support in LabVIEW. IFM is one company that makes a ton of really cool sensors and networking hubs that are largely IOLink capable. It should be relatively straightforward to develop a restful IOLink interface using GET/POST with JSON formatted commands. I am planning on doing this and was wondering if anyone has gone down this path before. https://www.ifm.com/us/en/shared/technologies/io-link/select-products/product-configuration-pages/dataline-tee-cable-wiring

What! Does lvserial acutally support regex termination strings? How is that accomplished? Is that capability built into an interrupt service routine or is it just simulated in a polling loop under the hood?

This one slipped under the radar but I think is finally a viable starting point for an open source TestStand Lite that was imagined many years ago. https://github.com/Tom-Lu/TestLite

Anyone know what ever happened to the late great LuaVIEW framework. I used it many moons ago and have an application for a scripting language that interoperates well with LV.

Wondering if anyone has tried to use this LUA wrapper library. It looks very promising and would be a great open source scripting tool for the LV community. https://github.com/antonie-coetzee/GLue See attached pdf documentation MLua Help.pdf
