I have the following situation: I have a cam that takes a photo every 5 seconds and saves the last 5 photos in an image folder, and an html page with a JS that processes the colours of those images after loading them in the page and also sends the results through ajax to the plc.
The thing is that when I execute the program directly from the browser it runs well. But when I try to run it from the PLC all the code has to be converted into blocks, and this seems to include the images as well. If I turn all the content of the program (with the images included) it also runs well, but the images doesn't update in real time like in the browser. If I only turn the .html into blocks but not the images, then the program can't load the images at all and it does nothing.
Is there a library to directly load a .jpg image in real timeto the plc or a way to turn the .jpg images to blocks in real time? If that's not possible, should I build a local server and do the processing there, and call it through ajax?
Thank you very much.
