@elektroniker86 Da müssen wir auch die Einstellungen zu sehen.

@elektroniker86 stell mal bitte auf debug
Ansonsten
@elektroniker86 sagte in JK BMS mit Modbus Adapter über RS485 zu TCP einbinden.:
"ReadInputRegisters: Invalid FC 32"

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
GmodbusMaster
RMMS (Radzio Modbus Master Simulator -
