Hello,

I created a Perspective Table with a Tag History “[Sample\_SQLite\_Database/ignition-peccollpppgm603:default]gantry\_10/machine 1/alarm2010“ **and this is working well.**

I am trying to do a template of this table for visualize de alarms of different machines. I tried to configurate a “Custom Tag“ but it is not working. Is there a way to do it?

Thank you for your help

Can you try using Expression in the TagPaths instead of Direct?

It has to be String TagPath. So there you can also access views.params. You can concatenate your basePath + tagName here

Yes, I tried. First 2 images are Expression and the configuration “String Tag path“, and in the 3rd image you can see the direct address working well. I don’t know what I am doing wrong.
