Eltako Drehstromzähler Modbus konfiguration

Homoran

@ma-sch sagte in Eltako Drehstromzähler Modbus konfiguration:

LSB steht meines Erachtens für LittleEndian

wo steht das?

storage order is from high to low.

ist BigEndian, wie auch sonst üblich
https://de.m.wikipedia.org/wiki/Byte-Reihenfolge

wendy2702

Zum Thema LSB

„
Das MSB (Most Significant Bit) ist das äußerste linke Bit und enthält den höchsten Wert in der Binärzahl, während das LSB (Least Significant Bit) das äußerste rechte Bit ist und den niedrigsten Wert darstellt . Diese Reihenfolge spielt eine entscheidende Rolle bei der Interpretation und Verarbeitung von Daten“

Homoran

@wendy2702
... bei BigEndian!

wendy2702

@homoran ich wollte nur sagen das es nicht „Little Endian“ bedeutet im Modbus

paul53

@ma-sch sagte: Das Protokoll findet man hier:

Laut Punkt 3.1 sollten alle Register vom Typ "int32" sein, wobei nur die Leistung (mit dem Faktor 1) auch negativ sein kann.

Ma Sch

So sieht die Allgemeine Konfiguration aus

und das ist die Logfile mit Einstellung "debug"

@ma-sch sagte in Eltako Drehstromzähler Modbus konfiguration:

das ist die Logfile mit Einstellung "debug"

@ma-sch sagte in Eltako Drehstromzähler Modbus konfiguration:

inputRegs","address":2,"deviceId":3,"type":"uint16le"

ist ja immer noch little Endian!
...und 16 Bit

und:
Grundsätzlich immer erst nur mit einem Register testen

wendy2702

@ma-sch sagte in Eltako Drehstromzähler Modbus konfiguration:

node: v20.17.0, js-controller: 6.0.11

Bisschen alt.

Haken bei "Aliases benutzen" entfernen.

Wie @Homoran schreibt erstmal nur ein Register eintragen.

Und den Kommentar von @paul53 beachten

Ma Sch

Hallo,

habe die Ursache gefunden ... Ich habe im Modbus noch einen weiteren Zähler, einen Eastron SDM630, dem habe ich versehntlich die gleiche Adresse gegeben

Richtige Konfiguration sieht so aus

30053	10	Totals active power	Gesamtleistung	W	int32be	2	1	0		value		false	false

@ma-sch sagte in Eltako Drehstromzähler Modbus konfiguration:

das geht natürlich gar nicht.

Aber davon war in deiner (nicht gezeigten) Konfiguration nichts zu sehen

wendy2702

@homoran wäre ja auch schön gewesen wenn @Ma-Sch jetzt mal Screenshots seiner config und die Register Einstellungen zeigen würde damit andere auch davon profitieren könnten.
