Dynamic OPC server

Wich mode can I use to set dynamically the OPC Server?
I want create a Data type where I assigned OPC Server in dynamic mode.

It it possible?

You can set the OPC Server and OPC Path at runtime using a script that calls system.tag.editTag(). See the very first code example on that page.

Ah, ok, now I see this option but where can I write this script in var Data Type?
I don’t much experience with data type.
Thank you so much

Oh, you want to use a UDT parameter to set the server? You’ll have to just play with it to see if you can get the curly-brace syntax to work.
