Hey everyone,

First time on forum, and relatively new to Ignition, though I have a good bit of Controls experience.

I’ve created a UDT and am trying to display the values using a PowerChart.

I’ve created the PowerChart and set up the tags to (I believe) the correct Storage Provider. However, the Storage Provider tree is empty under ‘Browse Tags’ unsure of what I’m missing. See image for more details on the setup.

Any/all help appreciated!

Thanks in advance.

With history set to On Change, Ignition won’t actually store anything in the historian until that value changes. Seeing that the tags set to memory right now, I am guessing that if you just manually update those values you should start seeing the history.

It is kind of a weird quirk that the initial values don’t get logged when you enable history.

I found the problem!

The postgres role/user that the Ignition gateway was using didn’t have CREATE permission on the public Schema. So Ignition’s historian couldn't create the sqlth\_\* tables it needed in the database.
