Einbinden von Modbus - R4DCB08 sensoren
-
@marc-3 sagte in Einbinden von Modbus - R4DCB08 sensoren:
Int16be hat aber nur eine Länge von 1
dann doch int32be
ich hab schief gedacht: 16bit sind 2 byte 
hab gerade nachgesehen, stimmt!
Bei länge von 2 hab ich auch (u)Int32be@marc-3 sagte in Einbinden von Modbus - R4DCB08 sensoren:
Poll error count: 3 code: "ReadInputRegisters: Invalid FC 3"
Da bin ich überfragt.
Die fuunction codes erzeugt der Adapter
fc3 istRead Multiple Holding Registers fc3
Quelle: https://en.m.wikipedia.org/wiki/Modbus
wieso das noch auftritt wenn da nichts drin steht ???
edit:
trag die gleichen Werte mal statt bei inputRegisters bei Holdingregister ein
manche Geräte wollen das so -
Eingangs und Holding nun das gleiche:
Interessant is der "unkown function code: 0x0, 0xc0" das ergibt rund 19,2°C, was für meinen Keller realistisch ist und was auch der Wert des ersten Temp Sensors ist:

ja, aber Haken bei Abfrage setzen

wir kommen voran! die 12714179°C aktualisieren sich alle ~1 sekunde (alle 1 Sekunde wird der Wert tatsächlich gesendet, daher ist die Polltime quatsch, ABER!!!! es kommt was an)
Jetzt muss man das nur noch in 8 verschiedene Temperaturwerte aufdröseln, entsprechend umwandeln, dann hätten wir es schon.
12714179 in Hex sind C2 00 C3 und scheint die Antwort auf die Anfrage davor zu sein.modbus.4 2024-10-20 21:28:12.583 debug [DevID_3/holdingRegs] Poll address 1 DONE modbus.4 2024-10-20 21:28:12.512 debug [DevID_3/holdingRegs] Poll address 1 -

@marc-3 sagte in Einbinden von Modbus - R4DCB08 sensoren:
aktualisieren sich alle ~1 sekunde
was ist denn das Intervall?
hier
https://forum.iobroker.net/post/1211358
waren es 10 Sekunden.@marc-3 sagte in Einbinden von Modbus - R4DCB08 sensoren:
Jetzt muss man das nur noch in 8 verschiedene Temperaturwerte aufdröseln, entsprechend umwandeln, dann hätten wir es schon.
nee, das sind verschiedene Register pro Sensor
@marc-3 sagte in Einbinden von Modbus - R4DCB08 sensoren:
ABER!!!! es kommt was an
Möglicherweise ist auch nur das Zahlenformat falsch.
wenn du uint32 hast mal int32 nehmen oder umgekehrt -
@marc-3 sagte in Einbinden von Modbus - R4DCB08 sensoren:
daher ist die Polltime
das ist die Dauer des polls von request bis zur Antwort
-
Es tut :
jetzt nur noch die Werte mit 0,1 multiplizieren und es ist erledigt

Spalte Faktor erscheint
also doch Int16!???

@homoran sagte in Einbinden von Modbus - R4DCB08 sensoren:
edit:
trag die gleichen Werte mal statt bei inputRegisters bei Holdingregister ein
manche Geräte wollen das sosteht doch auch hier
fc3 ist Read Holdingregister

@homoran
Naja, wenn man das lesen kann... Aber vielen Dank dir, für deine Unterstützung nun läuft es.nächster Schritt, schauen, was passiert, wenn's über 25,5°C wird (Länge 1 = FF = 25,5°C)
übernächster Schritt, alles über ModBus to ETH Adapter.Das alles aber erst, wenn ich wieder Zeit dafür hab.
Vielen Dank nochmal und einen schönen Abend noch! -

das sollte dann zumindest mit den Modbusadapter Einstellungen klappen.
Dann muss nur noch
der Konverter korrekt konfiguriert werden.@marc-3 sagte in Einbinden von Modbus - R4DCB08 sensoren:
wenn's über 25,5°C wird (Länge 1 = FF = 25,5°C)
dann doch Int32be??
was kam denn jetzt dahei raus?@marc-3 sagte in Einbinden von Modbus - R4DCB08 sensoren:

gerne und dito!

@Homoran Um das ganze nochmal abzuschließen.
ja es ist Signed16BE, trotz dessen, dass es 4 Stellig ist. Bei 32 hatte ich das Problem, dass 2 Werte zusammen genommen wurden.
Modbus Adapter per Ethernet hat heut auch geklappt.
Als nächstes kommen noch meine weiteren Boards dran, dann kann ich endlich sehen, was meine Fußbodenheizung so macht. Wenn ich es von meinem Brettaufbau verteilt fest eingebaut habe
(In jeden Verteiler kommt ein Board mich bis zu 8 Sensoren, und im Keller direkt an der Heizung auch an den Vor/Rücklauf.)
Insgesamt hat mich das nun keine 100€ gekostet. Alternative und sicher einfacher wäre alles in KNX gewesen, aber preislich ist as über Modbus und den günstigen Sensoren kein Vergleich.
