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.

Generic Ethernet module and assembly instances
So with EIP you essentially have 2 forms of communications (I may have some of the specifics wrong here, but the general info is correct). One is the communication used for IO devices over ethernet, such as a Remote IO. This has a specific minimum rate at which communication has to occur or it will cause an error in the PLC. These devices will show up in your Network / IO Tree. If you want to have the PC mimic one of these devices, you are probably looking at this library https://github.com/EIPStackGroup/OpENer.

Allen Bradley IO Block
I'm sure /u/dmroeder can chime in here, but as far as I'm aware pylogix, libplctag, and a few other libraries, use Level 2 (I think that's the term used by CIP) CIP comms to talk to the PLCs. It's the same comms used by HMI etc. The IO though would probably only talk Level 1 comms which has more guarantees on reliability and RPI etc. You could possibly use something like OpENer for this.

Raspberry Pi + ControlLogix EtherNet/IP Integration
It sounds like what your partner is asking for is a EIP adapter. It's the slave device (IO) as opposed to an EIP scanner, which would be the master (PLC). A few years ago I had an application similar to this that fell through. I never for into development but identified this library; https://github.com/EIPStackGroup/OpENer.
