Implementierung, RS485 via Adapter (Modbus RTU)

Open aerucu opened this issue 11 months ago • 3 comments

Ist es möglich in den Modbus Proxy einen RS485 via Adapter (Modbus RTU) zu implementieren?

Mein Wechselrrichter hat einen RS485 Adapter und keine Nettzwerkanbindung.

Ich wünsche mir folgende Eingabemöglichkeiten. Evtl. mehrfacheingaben möglich?

modbusproxy:
    port: 502
    device: /dev/ttyUSB0
    baudrate: 9600
    comset: "8N1"

I have the same request. It would be very helpful to have USB RS485 adapters implemented. Thx

@rabattcoupon, TCzerny's fork has now implemented Modbus RTU.

At least i tried it in a branch. Hard to develop because I can't test on my site.
