I am looking at cleaning up my first Ignition project that was released to the wild (Under v8.1). While it works I didn’t make the best design choices which has resulted in a complicated (IE ugly) maintenance process. The application itself is basically a data logging system that monitors multiple…

This may be a stupid question, but is there anyway to automate adding the tag paths when a new instance of a UDT is created?

No. Perhaps in v8.2 if the gateway events turn into text-based resources (currently they are binary).

Some more questions By "fifth event" do you mean the fifth time the same event is triggered on a single instance. Or do you mean the fifth global tag change event across all instances of the UDT? Is the length of the length of the global thread pool related to the 5 events above (which is basic…

[image] peter: Thinking out loud here, one possible way to help improve the system would be to allocate the tags into tag groups whose execution times are based on prime numbers. I’ve done that before in other systems to ensure that events stay separated in time. No, this is mostly wishful th…

[image] peter: The value change event for a single UDT instance is triggered 5 more more times before the script itself can complete It's this one, if you mean the "change event for a single UDT instance member", because your script is on a member tag, not the instance itself. If this member…

[image] Kevin.Herron: You never exhaust the thread pool event scripts I think I interpreted "exhaust" wrong in my first pass - if by "exhaust" you mean all 3 are currently busy, then that's when the per-tag queues start filling. I was thinking exhaust as in an unlimited thread pool creating …

OK. I’m resorting to low syllable words because I think I am confused by the terminology and feel I am still missing something. I have a UDT that has a value change script attached to one member. I have N instances of the UDT defined as tags in the project. Is the issue with the value change scr…

[image] peter: Is the issue with the value change script being triggered multiple times on a single instance of the UDT? Or is the issue if a number of the N instances all trigger the change events simultaneously? Well... it could be both. Every member of every UDT instance has its own even…
