Tag Historian Insert Data into Tag with Timestamp

Hey Everyone,

With IG AB driver, I can not grab data reliably faster than 250ms. To combat this we store the needed data in an array at a faster rate and a script goes though an array and inserts the data into a table to rebuild the tag data. However, my company has decided to move to Ignition Edge for this project with tag-historian and I no longer have access to a DB.

Does anyone know how to insert data into a tag-historian tag with a timestamp attached to it?

Thank you,
DG

The only way to manually insert values into Tag History is to use system.tag.storeTagHistory().
https://docs.inductiveautomation.com/display/DOC81/system.tag.storeTagHistory

Note that, on Edge that means you will need the Compute module (I believe).

Of course if you have a Standard Gateway somewhere else with access to this data, then you can always do it there.

Don't know how I missed that call in the manual. This is exactly what I needed.

Awesome! thank you.
