I am trying to get more familiar with the WebDev module and trying to understand some of the use cases for it. I don't have any requirements to send data to ignition but I was wondering what other use cases you are using it for?
In the advanced perspective class, we used it to save images to a database and then pull from the database to be displayed on a screen. Not sure if that was a best practice or just an example of what it can be used for.
If you don't mind sharing, what else are you using it for? thanks!
I have not implemented it yet, but I hope to use it to allow tools like PowerBI to pull data from the gateway making use of its system.tag.queryTagHistory() function.
Back before Perspective, we used it to allow us to have a web based front end dashboard.
I have also used it to scrape data from third party device web UI's (e.g. a device which only has a private web interface), where I didn't have a means to connect via some other means.
--Endpoints for other applications/systems to send data or read data from Ignition.
---Example: ERP system sends data dumps daily
-- Custom JS/HTML/etc functionality as an example we tried out a document viewing application which had 3d model viewing so we could use this to view CAD/STL/files. (Performance was hit really hard using this so we didn't end up using this for production.
-- Another custom JS tool we tried to add was cytoscape:
Imagine the above except each block is a cell on a line and instead of a network diagram it's more of a full plant floor process with a plant floor diagram as the background. It allowed users to pretty much build and place their process then save the config to a db.
You can get pretty creative with it and it has many helpful use cases.
