Is there any way to make UDT parameters dynamic? I would like to specify a tagname for a UDT tag and have several parameters specified as database style tags and their values determined by a database query based on the tagname. These parameters would then be used in the configuration of several OPC tags (such as the OPC path) within the UDT. Any workarounds would be appreciated.

you can make them dynamic by using system.tag.editTag

and overriding the parameters
