Alfen Wallbox auslesen über Modbus

[Henson05]

Hallo zusammen,

Ich versuche mit Modbus Daten aus der Alfen Wallbox auszulesen.

Leider verstehe ich nicht, wie ich die Modbus Adressen lesen kann. Kann mir da jemand ein Beispiel geben? Ich bin schon ewig dran an dem Thema, komme aber keinen Schritt weiter. Als Einstieg möchte ich einfach den Namen oder den Hersteller auslesen (PDF S. 10)

Hier ist die Modbus Dokumentation zu finden:

Das Device habe ich in Moment wie folgt angelegt:

warum master wenn in deiner Doku steht Slave Addr 200 ?
Wie kommst du auf Register Nr. 40099 wenn in der Doku Register Nr. 100 für den Name steht ?
BTW : Bitte in Zukunft Code Tags benutzen.
