Hi Alvaro, I had a look and I have to say I think the progress was even so limited, that it never left the branch he worked on. https://github.com/apache/plc4x/tree/54115fc561c9ff4b3600b0fe15c49949dac51828/plc4s
There was a branch, but I deleted that one or two years ago.

In our lab we have two PLCs (Schneider and Siemmens) with Modbus outputs. And a gateway converting from Modbus serial to TCP. And also a Twave with Modbus output. So we can help in the testing. Also, we use two Modbus simulators that can help also. > > I think if you go back to the time where the PLC4X repo moved to > Apache, you will find some Scala bindings.

If I feel confident about putting real effort in creating the bindings, I will research to find this work. > > Unfortunately my company has a Kick-Off event on January 31st ... > usually I'm a little destroyed the day after so wasn't planning on > going to Brussles super-early in the morning ...

The IoT devroom is on Sunday, so it is perfect for you ;) https://fosdem.org/2020/news/2019-10-01-accepted-developer-rooms/ https://lists.fosdem.org/pipermail/fosdem/2019q4/002929.html Next week I will propose you a possible talk about PLC4x. It is a great place to present the project, as probably you know. > > By the way ... we do have new TAC rules to make it easy for Apache > Committers to have the trip financed by Apache. > I have already booked my plane and hotel :) Cheers! > Chris > > > > > Am 05.12.19, 10:17 schrieb "Álvaro Del Castillo" < > [email protected]>: > > Dear all, > > On Thu, 2019-12-05 at 08:53 +0000, Julian Feinauer wrote: > > Hi all, > > > > I just realized how much activity we currently have on our > list, with > > regard to our baseline (and the last months). > > Its really nice to have so many new people here, especially > Alvaro > > and Sebastian (Wiendl) have to be pointed out. > > So lets to keep everybody as motivated as possible and help all > > newcomers with the start and their stack to keep them with the > > project : ) > > My feelings from my first steps in the project are that you are a > receptive, open and honest community willing to grow with new > members. > And I am very happy with that and I have recommended in my > company to > join the project because I think that we can work together > fruitfully. > > So during the next weeks I will bring some real effort to the > project > with PRs about our findings in modbus and opc-ua drivers.
