Hello, I currently have an application in which I save data to Edge Panel periodically. Is there a way to do it with a trigger—that is, every time I activate a bit in the PLC, save the data? ---

What data are you saving? Are you saving it to a file? What are you using the data for? Why are you storing it? If you are just saving to a file(like a .csv) you could probably get away with configuring a gateway tag change event to write another row to the CSV every time the PLC signals to. ---

The data I’m storing are PLC tags, and I’m saving them to later display a history of those values. However, I only need to save them with a trigger from the PLC, not periodically ---

You will have to script this, typically on a tag change event, as the primary non-script tool to do triggered value saves is the SQL Bridge module, which requires a DB connection, and is therefore not usable on Edge. ---

Couple of options, both utilizing a tag change script: 1. Store short term "transaction" history to a dataset tag on Edge gateway. 2. Store long term to database using message handler sent to a full gateway w/ SQL Bridge. ---

IgnitionEdge running in docker close to Machine and store data as per Edge “Store locally up to 35 days or 10 million data points, whichever first.“ we have 3rd-party application need to access to storage data .. Is there any way to get access outside ignition to this local DB to direct query these data ??? ---

Only if you have “full” Ignition too. Edge→Full→3rd party ---

You can license WebDev in Edge, and expose an API (not a DB connection) that invokes `system.tag.queryTagHistory()` on behalf of the external user. If you need any real DB activity, you need Standard Ignition, not Edge.
