Hallo in die Runde,
ich hoffe ihr könnt mir weiterhelfen.
Habe hier einen Goodwe GW3648-EM mit LX U5.4-L dem ich gerne seine Daten über RS485 seriell entlocken möchte (nicht über TCP).
Was man vom WR so abrufen konnte:
FW Version 3121217
ARM FW 02034.00
BMS Version 27136
Ich versuche die RS485 über einen Waveshare Adapter (FTDI) RS485 to USB abzufragen.
Der Adapter hängt via USB an einem Raspberry 4B mit IOBroker und Modbus Adapter.
An der RS485 habe ich sowohl die Pins 1 und 2, 3 und 6 sowie 1 mit 3 und 2 mit 6 verbunden getestet
und auch jeweils + und - vertauscht, leider jeweils ohne Erfolg (im Forum gab's mal einen Tip bezüglich der Parallelschaltung von Pin 1+3 und 2+6. Deswegen auch dies ausprobiert!).
Die Kommunikation ist konfiguriert mit 9600bit/s, 8/N/1, Geräte-ID mit 247
Bekomme in keinem Fall eine brauchbare Kommunikation zustande.
Der Modbus Adapter startet, wird kurz grün und geht dann wieder auf gelb.
Ich hoffe, dass Ihr mir evtl. auf die Sprünge helfen könnt!
Hier mal die Meldungen nach Start der Modbus Instanz mit debug:
