Is an easier way to read the UDT tags with AAHMI.
My recent experience with node-red is blowing me away with how easy it is to read/subscribe tags including UDT tags.
First, the Tag Browser brings up all tags in the processor, then clicking on the tag that you want to read/subscribe will get it into the Tag list with proper data type automatically defined.

In the 1st screenshot, DTCurrent is a UDT tag that contains date time info AND a custom string length of 20. The FreeRunning tag is a TIMER. As you can see, in the node-red they are STRUCT type.
In the 2nd screenshot, showing all the atomic data type and the debug data from the two tags

The ethernet driver module that I use is the 'node-red-contrib-cip-st-ethernet-ip' and on Github:

bachphi, that's nice.
Could you post any more info or screenshots (like setup flow text file and a screenshot)?
I have a repository on GitHub which showcases Node-RED and pylogix / pycomm3 libraries, which can be seen here:

There is also a link to this post so anybody looking for more information can get it here.

Godra, I was only testing out its capability. You are way far ahead of me.

Your testing might actually simplify the overall approach and improve the knowledge of those who dare to try using Node-RED and this particular module you used.
I might eventually try this myself.

Wat!? You're GitHubDragonFly? I did not know that.

dmroeder, there is a few more posts in this forum that suggest the same, like these 2:

- https://www.advancedhmi.com/forum/index.php?topic=2563.msg16237#msg16237
I did bother contributing to your pylogix project since it's open sourced and people can find it useful.

I guess I missed those threads and never made the connection. Thanks for the contributions!

Dragonfly! The animated series or the scary one?

bachphi, just so you don't find dragonflies scary here is a link to 14 Fun Facts about dragonflies:

OK, you were not inspired by the 2015 movie.
I know enough about the dragonfly.
Did you know when the dragonfly is flying low, it means it's about to rain and when it's flying higher, it means it's sunny?
-
I did not know that, sounds like it is susceptible to atmospheric pressure or something else related to the weather.
All in all, I am not much into dragonflies even though it's a part of my GitHub username.
