Is it possible to create a tag list (array) via javascript, possibly with a filter? The usefulness: For example, you have a data block with parameters that belong to a certain object. Not every object has the same number of parameters. You then declare the data block as follows: DB_PAR.PT01.Par1, DB_PAR.PT01.Par2, ... You could then create a tag list with only "DB_PAR.PT01" as a filter in which all parameters would then be placed. From the received (taglist) array you can then do fun things. In short: Create a tag list with a wildcard or other filter. If it doesn't exist, consider this post as a feature request. Thx

Maybe you can use DataSets for your purpose. See if this post about DataSet object can help you: https://support.industry.siemens.com/forum/es/en/posts/write-on-dataset-object/253580

That said, this object could be useful as the result of some sort of "lookup" method. So a dataset object with wildcard would be great and make everything more powerful. For example. You have a system consisting of several objects with UDTs and some other parameters. Every system is about the same, but one has more than the other. These are then built up with "structures" in a data block. You could then search on the first part of the tag name, and work with the result (multiple tags) such as showing certain faceplates, or not, etc... But I'm already pretty sure it isn't possible (yet). So to Siemens, pretty please, create a dataset with wildcard?
