Eltako Drehstromzähler Modbus konfiguration

Ma Sch

Hallo,

ich habe den Eltako DSZ15DZMOD-3x80A Drehstromzähler
Das Protokoll findet man hier:
https://www.eltako.com/fileadmin/downloads/de/_bedienung/Modbus-RTU_protocol_specification_for_DSZ15DZMOD_V1.6_English_version.pdf

Die einzige Änderung am Zähler, die ich gemacht habe, ist die Adresse, diese habe ich auf 3 gesetzt. Wie ich die Dokumentation interpretiere, ist die Parität keine, es gibt ein Stopbit
Es sind 4 byte große Register, also 32 bit, LSB steht meines Erachtens für LittleEndian und der Faktor ist 0.01.

Das ist meine Konfiguration

_address	deviceId	name	description	unit	type	len	factor	offset	formula	role	room	cw	isScale
30053	3	Leistung	Leistung	W	int16le	1	1	0		value		false	false
30001	3	Spannung	Spannung L1 N	V	uint16le	1	0.01	0		value		false	false
30003	3	Spannung	Spannung L2 N	V	uint16le	1	0.01	0		value		false	false
30005	3	Spannung	Spannung L3 N	V	uint16le	1	0.01	0		value		false	false
30073	3	Energie Total	Energie Total	kWh	int16le	1	0.01	0		value		false	false

allerdings passen die Werte nicht mit denen die am Gerät angezeigt werden. Die Spannung wird mit 260V angezeigt, auch die Leistung und Totale Energie haben falsche Werte.

Sieht jemand meinen Fehler?

Danke

ohne Konfiguration und debug-log leider nicht

@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

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.

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

@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

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

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.
