Fischer Panda an Cerbo

Hallo!

Mein Fischer Panda Genset lässt sich ab Cerbo Version 2.90 nicht mehr über die Autostart Kontakte am Fischer Panda Panel Starten. Auch der Start über Modbus funktioniert nicht mehr. Vom Cerbo geht es allerdings. Bis zur Version 2.89 Funktioniert es auch. Ist das Problem bekannt?

Kannst du zum testen noch mal zurück auf eine 2.8X Version gehen?

Im Firmware Menü sollte es eine option geben auf die letzte Version zurück zu gehen.

@VisuShip Has the Autostart issue been resolved when updating to VenusOS v3.11?

Regarding starting/stopping the generator through modbus: it is no longer possible to write to register 3223 directly, as this is controlled by the generator start/stop. To manually start the generator please use register 3500.

Hello!

Unfortunately, the address 3500 doesn't work either. What kind of way is there to start the Fischer Panda via MODBUS?

It works here with this simple python script:

from pyModbusTCP.client import ModbusClient
c = ModbusClient(host="venus.local", port=502, unit_id=1, auto_open=True)
c.write_single_register(3500, True)

Make sure to set to correct Unit ID:
