I will contact both of you to understand your concerns a bit more, since these toolkits (IO-Link for LabVIEW and TestStand) were developed exactly to accommodate the scenarios you describe. I can clarify a couple of things here as well: - Our runtime licenses are always perpetual, never a subscription that could expire. - For development licenses we offer both subscription (to get going for less) and perpetual (if you know you want to use it for a long time). - We do offer discounts on license bundles. So if someone has "hundreds of systems", they could use that option. - The software in question currently has more than 3,000 hours of development time behind it, with ongoing improvements. I assure you, no matter when you begin it will be a long time before you have something that is close to what you could buy today. And at that point you wouldn't consider giving it away for free 🙂. This toolkit parses the entire IODD XML standard, which is huge. It is not quite the same as picking the 2% you need today, and discovering that the next device you want to connect uses a different part of the standard...

I thought this was an interesting exercise so here is my attempt. OpenG has some image tools and one of them is the ability to open a GIF, but for some reason it crapped out and died with your GIF even after resaving it to something much smaller. I did find some other GIF API over on the dark side and instead used that. Attached is a zip, extract it and run Demo Saving Button. It will show the first image. Then when you click the image it cycles through the first half of the GIF and waits for the simulated save process to complete. Once it is complete it rotates through the second half of the images, and then after a few seconds returns back to the first. Parsing of the GIF takes time so I put in the GIF images as a constant, along with the code to parse the GIF. I also set the pane to be the color of the (0,0) pixel in the hopes it will blend in better. Honestly this could be turned into a QControl and be made very seemless. Demo Saving Button Gif.zip
