Hi all,

I have a table with several custom properties set up. The table is creating a read out for yields between blending system and filling system. The tags were in several different providers and the paths are dynamic (i.e. Blend system 1 can go to filling system 3). To make the table I chose to use the custom properties to use expressions for the dynamic path and the table was created with cell bindings to the property.

What is the simplest way to write the table custom properties value to a tag?

Welcome to the forum!

This feels like use for a UDT with reference tags, as you can reference tags in different providers.

Using bindings on the client will only work when that screen is open.

If you are wanting to track data at that exact time of rendering the table then you can use `system.tag.write*`

I tend to agree that this logic might be better done in tags rather than in the gui. Certainly, the tags' values should _never_ rely on a GUI client in order to be updated, for the reason in Ben's reply:

The only time tags should be supplied their values from the GUI is if they're setpoints.

What are some examples of the expressions in your custom properties that are providing the values for the table?
