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.
