> This is a bad idea, you should be using Gateway Tag Change events. There are a couple of methods to do this, if the script is generalized enough you can run the same script for all of the tags and just assign those tags to the tag change event (Gateway Tag Change Events can be triggered by multiple tags). You could also generate a top level list of tags, and at a trigger run the script which does all of the work for all of the tags at once. Reference for why this is a bad idea: [https://doc…](https://docs.inductiveautomation.com/display/DOC81/Gateway+Event+Scripts)
