Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Pycomm3 CIPDriver.discover() questions
Probably best to start a discussion in the repo. https://github.com/ottowayi/pycomm3
- Anybody got any useful Python tools?

Read array of structs using CIP protocol
If you want to see the code, it's on github. Everything starts with get_tag_list in pycomm3/logix_driver.py. And _parse_template_data has most of the logic for parsing the struct attribute definitions. The code is pretty complicated, hard to follow, and not something I'm particularly proud to show off. I've been meaning to refactor it, but I've been avoiding it since it took so long to get working.

Factorytalk datalogging to Raspberry Pi?
To elaborate on what I think u/TheDevilsAutocorrect is getting at, don't do the data logging on the PanelView. Use [Pycomm3](https://github.com/ottowayi/pycomm3) or [pylogix](https://github.com/ottowayi/pycomm3) to log directly to the Raspberry Pi. You can log to CSV pretty easily with either library.

Any pycomm3 users want to help test the next release?
Here are the basic steps, if you have any questions feel free to ask there.

Reflex Minigame (PLC and RP Pi)
If you're using a MicroLogix with ethernet you can try pycomm3. It's a pure Python Ethernet/IP library I maintain. It started as a port of pycomm to Python 3, but since has changed significantly. It has "support" for MicroLogix thru the SLCDriver. You may need to refer to the pycomm documentation for addressing examples, though. When I was at an integrator we never used MicroLogix PLCs, so any testing was done against a SLC. If you try it out and run into any issues, feel free to open up a issue on GitHub.
