JK BMS mit Modbus Adapter über RS485 zu TCP einbinden.

[Elektroniker86]

@sierra sagte in JK BMS mit Modbus Adapter über RS485 zu TCP einbinden.:

In deiner Text Datei liest du aber 1 und 2 aus.

Ja ,..... das habe ich auch noch nicht so ganz kapiert. Denn eine Batterie muss der Master sein 0 und der 1. slave die 1 und der 2. slave die 2 usw. damit die Batterien im Parallelbetrieb funktionieren.

Das funktioniert auch hervorragend mit meinem Sunny Island 8.0

Wenn ich mich mit den Batterien dann per USB Dongle bzw. PC Software verbinde kann ich unten als ID eingeben was ich will und bekomme immer eine Verbindung und kann oben bei den Reitern zwischen den Batterien switchen.

@sierra sagte in JK BMS mit Modbus Adapter über RS485 zu TCP einbinden.:

Werkseinstellung ist glaube ich 0 - 4G-GPS blabla bei UART1
Irgendwo hatte ich damals gelesen gehabt, dass man da 1 einstellen soll

Das habe ich ausprobiert, allerdings bekomme ich dann garkeine Werte mehr.

Das habe ich ausprobiert, allerdings bekomme ich dann garkeine Werte mehr.

Wirklich? OK, ich habe es auf 1 eingestellt und es arbeit... Hmm interessant

Hier ist die Beschreibung mit den DIP Schalter, also nach deinen einstellungen ist es ID 0 und ID 1

Also an deiner Stelle würde ich wirklich mal schauen die Kommunikation mit einer Batterie stabil zum laufen zu bekommen, wenn das geklappt hat dann die 2. Batterie dazu, je nachdem ID 0 oder ID 2

@elektroniker86
Einen Denkanstoß gibt es noch.

Dein grünes Patchkabel ist ja dein TCP Adapter.
Hänge das mal an den RS485 neben dem CAN.

Die anderen zwei RS485 sind theoretisch für die "interne" Kommunikation, also die Master-Batterie wo der CAN aktiv ist, liest über die "internen" RS485 Anschlüsse die weiteren Batterien aus.

Du hängst jetzt in der "internen", sendest paralell zum Master auch deine Abfragen über TCP, das ergibt eigentlich einen Konflikt.

Bei der RS485 Kommunikation darf es nur einen Master geben der Befehle senden darf und das ist in diesen Fall die Batterie.
Dein TCP Adapter ist aber auch ein Master und kann somit die Fehler verursachen weil gleichzeitig gesendet wird.

Vielleicht kommt die JK-Software am Rechner damit klar weil es als Sniffer arbeitet und die Daten einfach nur lesend abgreift.

Teste mal den anderen Anschluss neben dem CAN

@sierra

Verstehe was du meinst, werde ich noch ausprobieren.

Habe auch mal im Modbusadapter probiert die ID0 auszulesen da kommen aber keine Werte.
Und bei ID 1 kommen tatsächlich nur die werte 2. Batterie (slave)........
Ausserdem habe ich noch mit den Timern rumgespielt.... ganz hoch 20 30 sekunden bis zu ganz runter zu 1 Sekunde da kann ich keinen unterschied feststellen. Manchmal liest er alle Werte manchmal kommt der Fehler früher und dann werden nur ein paar Werte abgeholt ......
Mist, so nah am Ziel und doch ist es scheisse.....

[Elektroniker86]

Folgendes steht im Log wenn ich den Master abziehe und ich nur die Batterie mit der ID1 abfrage.
Habe die Widerstände der Zellen mal rausgenommen, brauche ich sowieso nicht.
Die Werte kommen alle rein im selben Zyklus wie auch der Adapter neustartet (Timing Einstellungen)

@sierra

Ich habe auch den RS485 Port neben CAN (für Inverter) ausprobiert, kann aber kein unterschied feststellen. Werte kommen alle rein (ID1) aber der Adapter startet immer wieder neu mit oben genannten Fehlern im Log

[Elektroniker86]

So, nochmal ein bisschen rumprobiert, der RS485 Port neben dem CAN Port funktioniert nur bei der Slave Batterie (ID1) da bekomme ich auch alle Werte, die im Holding eingetragen sind aber auch mit den gleichen fehlern.

Beim Master (ID0) funktioniert der RS485 Port nicht. Auch logisch da ich ID0 ja nicht abfragen kann da es nur ein Master geben kann.

Die Konfiguration, dass man die Batterien als ID1 und ID2 einstellt habe ich ebenfalls ausprobiert, aber dann erkennt der Wechselrichter nur die eine Batterie wo auch das CAN eingesteckt ist und zeigt auch nur den SOC von dieser an. Bei der Master-Slave Einstellung erkennt der Wechselrichter beide Batterien als eine und der SOC wird dementsprechend auch angezeigt.

Also die Master Slave Konfig muss eigentlich so bleiben.....

Gibt es nicht ein Modbus Adapter ioBroker oder TCP die nur die Daten als sniffer abgreifen so wie die PC Software das tut?

[Sierra]

@elektroniker86 Alles klar, das bedeutet, dass ich mir dann auch was einfallen lassen kann wenn die 2. Batterie ankommt.
Oje, das werden wieder schlaflose Nächte

[Elektroniker86]

@sierra

Ich hab in irgendeinem Forum gelesen das jemand die BMS mit einem ESP32 über Bluetooth ausliest und per MQTT verschickt.

Hab aber noch nicht so ganz gecheckt wie ich das installieren muss. Ein ESP32 hab ich sogar auch noch da.

[Sierra]

@elektroniker86 Ja aber angeblich läuft es nicht so ganz stabil. Bei mir ist es etwas einfacher, mein Raspberry Pi ist gleich neben meiner Anlage, also USB-RS485 ist absolut kein Problem, hab ich ja jetzt auch im Einsatz.
Schlimmsten Fall bau ich mir einen Sniffer über Python damit ich die Werte raus bekomme.

Mal sehen, die 2. Batterie sollte eigentlich eh bald kommen, ist ja schon 1,5 Monate unterwegs.
Wenn sie ankommt, dann wird weiter getüftelt bis es läuft

[Sierra]

@elektroniker86 Habe gestern endlich meine 2. Batterie bekommen.
Hat eh nur 3 Monate gedauert

Also, anscheinend geht es wirklich nicht dass man über einen RS485 Adapter die Packs ausliest.

Ich habe es nun mit 2 Stück USB-RS485 (liegen ja beim BMS bei) gelöst.
Man muss halt 2 Modbus-Instanzen machen, eine mit Adresse 0 und eine mit Adresse 1

Die Anlage liest über CAN auch beide Batterien aus, funktioniert alles.

Sollte also mit 2 Stück RS485-TCP Adapter auch funktionieren, ansonsten sehe ich keine andere Lösung.

Grüsse

@elektroniker86
wo hast die Register belegung her. in den PDF daten stehen ganz andere Register drin die nur teilweise funktionieren.

[Sierra]

@KlausAnders
Um welche Register geht es?
Die PDF ist schon richtig...

[KlausAnders]

@sierra said in JK BMS mit Modbus Adapter über RS485 zu TCP einbinden.:

@KlausAnders
Um welche Register geht es?
Die PDF ist schon richtig...
im Pdf gibt es keine ungeraden Adressen, nur länge 2 oder 4. Zu deiner vorlage fehlen damit etliche Werte. Das auslesen mit deiner vorlage funzt, nur das schreiben von Schaltern, z.b. Laden Entladen bekomm ich nicht hin.

[Sierra]

@klausanders
Da gebe ich dir Recht.
Es ist schon verwirrend, in der PDF stehen auch die Längen.
Für Laden Ein/Aus sind 4 Bytes vorgesehen.
Im iobroker werden bei Länge 2 angezeigt, aber da werden vermutlich 1 Länge 2 Bytes verwendet, High und Low.

Egal, ich habe mal versucht zu schreiben, also das funktioniert mit den Adressen die in der PDF steht.

Als Kontrolle ob wirklich Ein oder Aus mit den anderen Registern:

Balancer Ein/Aus zu schreiben funktioniert nicht so wirklich, da allein schon 1500 drin steht. Keine Ahnung

Da ich aber die ganzen Schreibbefehle nicht brauche, habe ich mich damit nicht wirklich beschäftigt.
Im Heimbereich ist das auch nicht wirklich Notwendig finde ich, warum sollte man da was laufend verstellen?
Einmal eingestellt und die Anlage läuft.
In einem Camper würde ich es verstehen wenn man da was abdrehen möchte

Ich habe auf meinem BMS die letzte Firmware drauf, neuere kann ich leider nicht mehr updaten da der Support für <V19 eingestellt wurde. Eine aktualisierte Registerliste wäre mal was tolles, ich denke da hat sich einiges getan die letzten Jahre.

[peterfido]

@sierra Man sollte auch nicht zu oft schreiben. Je nachdem, ob das Gerät Parameter im Flash speichert, ist da früher oder später eben dieser hinüber.
