CWT-BK-2222 lässt sich nicht mit Modbus Adapter auslesen

JB_Mystery

Hallo zusammen,

habe mir einen CWT-BK-2222 gekauft, um mein SmartHome zu erweitern. Die Idee war diesen über Modbus zu integrieren, was aktuell leider nicht funktioniert. Evtl. hat jemand von euch eine Idee warum es nicht klappt. Danke für Rückmeldung.

Hier jetzt die Gegebenheiten:

Gerät ist über das Configtool erreichbar und steuerbar. Dort habe ich auch die IP angepasst.

Ich habe aktuell mal Eingang DI2 beschaltet, damit man die Funktion sieht.

Zudem habe ich eine Software, die auch Kommunizieren kann.

Der Modbus-Adapter ist genauso konfiguriert.

Leider erscheinen im Log immer diese Warnungen und der Adapter steigt mit Error aus.

Aktuell nutze ich nur diese Eingangsregister.

Welche auch den Vorgaben entsprechen und mit den anderen beiden Methoden funktionieren.

@jb_mystery Function Code 2 sind Diskrete Eingänge.

Möglicherweise liegt hier schon dein Problem.

Ich würde aber auch nur mit einem Register Testen und erst wenn das Funktioniert würde ich weitere hinzufügen.

Was mich etwas stutzig macht ist das laut deinem Tool 8-Bit ausgelesen werden wenn ich das richtig interpretiere, im Dokument aber Unit16 steht.

@wendy2702
Das habe ich natürlich auch alles getestet. Es ändert sich nur die Warnmeldung. Handler 2 anstatt 4.

modbus.3
	2024-05-05 11:51:38.951	warn	Error in handler for 2: RangeError [ERR_BUFFER_OUT_OF_BOUNDS]: Attempt to access memory outside buffer bounds

Und als Diskrete Eingänge kann man ja keinen Typ mehr vorwählen.

Aber du hast Recht, komisch ist das mit den Bits und dem Dokument UINT 16. Aber Bits kann ich ja nicht im Adapter wählen.

Wenn ich alles auf UINT 8 umstelle, müsste ja 4 raus kommen.

Tut es auch in meinem Tool, nur der Adapter schluckt es leider auch nicht.

JB_Mystery

Hat keiner mehr Ideen für mich?

Oder Tipps über Produkte die ich in ioBroker einbinden kann mit mindestens 16 Eingängen und 16 Ausgängen.

Danke euch.
