@elektroniker86 sagte in JK BMS mit Modbus Adapter über RS485 zu TCP einbinden.:
Add inputRegisters
bitte Holdingregister nehmen
Und besser beim Port 502 bleiben.
@Elektroniker86 : gibt es bei dem Konverter noch ein erweitertes Menu oder kann man da wo TCP Server steht was anderes auswählen?

Ich habe jetzt das Register beim Reiter Holding eingetragen. und bei eingang rausgelöscht. Hoffe das ist richtig so?

@elektroniker86 sagte in JK BMS mit Modbus Adapter über RS485 zu TCP einbinden.:
ERR_BUFFER_OUT_OF_BOUNDS]: Attempt to access memory outside buffer bounds
Das sieht für mich so aus als wenn die Antwort zu lang ist und der reservierte Buffer nicht reicht.
In deinem Link aus dem JSON steht für länge 0, hilft uns aber auch nicht weiter.
Software zum testen:
ModbusPoll

Ich habe zum Test jetzt auch mal noch ein ELFIN RS485 Adapter probiert aber auch hier das selbe

edit!
hast du den in der Zwischenzeit eingestellt?
Warum?Das ist im Moment der einzige Fehler

steht 0, nicht 4
Ich habe es so verstanden das ich den so einstellen soll

ist was?
gibt es da was einzustellen, was nicht zu den Adapter Einstellungen oder WR Einstellungen passt? -

RMMS (Radzio Modbus Master Simulator
Den habe ich mal runtergeladen, aber da passiert überhaupt nichts habe die verbindung über den usb und den tcp Adapter probiert unten bei TX RX passiert nichts.
Mit dem Programm vom JK BMS klappt die Verbindung mit dem usb Adapter einwandfrei.

mit dem usb Adapter
den sollte man immer nehmen, wenn möglich.
Einen TCP2RS485 Konverter zwischenzuschalten bringt immer weitere Fehlermöglichkeiten mit sich -

Ja, habe aber keine andere Möglichkeit da die Technik der PV Batterie in der Garage ist

Kann es sein das etwas mit der Adresse nicht stimmt ? Sollte man mal eine andere her nehmen?
Habe auch nicht verstanden warum wir jetzt die Adresse um die Spannung abzufragen in holding eingetragen haben, dachte holding ist nur um Werte zu setzen?
