The mission of the Apache PLC4X project is creating a set of libraries for

 
communicating with industrial programmable logic controllers (PLCs) using a

 
variety of protocols but with a shared API.

There are no issues requiring board attention.

We have been continuing to port existing drivers to the new code-generation

framework. Also have we been implementing new protocols (Mostly based on paid

gigs from the industry). A lot of bug-fixing has been done and we're looking

forward to a big refactoring and brainstorming Hackathon form 2019-12-17 -

2019-12-19 in Weinheim, where we are going to work on a proposal for the

version 1.0.0 API.

## Community Health:

This quarter for most of the time activity on the mailing-list and in the

commits had dropped to worrying levels. This was mainly related to high

workload on the day-jobs of the community members. However in the past 2-3

weeks a lot of new people have joined discussions and submitted PRs and the

existing comitter- and PMC activity has picked up again.
