    @sven79 sagte in modbus errors & exceptions:

    Welchen Hinweis geben mir die genannten Fehler- und Exceptioncodes?

    wenn ich das richtig lese kommen die Error Codes von deinem Gerät.
    Gibt es von/zu/auf diesem mehr Infos?

    Das ist ein RS485/TTL Board, angeschlossen an einen ESP32 auf dem Tasmota mit Modbus-TCP-Bridge läuft.

    Ich habe testweise eine neue Instanz des Adapters gestartet, die lediglich ein Input Register von jedem Slave (ID 1, 2 und 3) liest - funktioniert einwandfrei.

      Bus voll??

      welche Einstellungen?

        Inwiefern kann der Bus "voll" sein? Was führt dazu und woran erkenne ich das?

        Die Adapter-Einstellungen sind unverändert auf den Standardwerten. Verbindungsparameter sind entsprechend auf die IP Adresse und Port des ESP32 gesetzt, Geräte ID ist 1, mehrere Geräte-IDs ist aktiviert und der Typ ist auf "Master" gesetzt.

            Die drei Stromzähler (Eastron SDM72D-M, SDM120-M, SDM230) sind auf 9600 Baud, 8 Datenbits, keine Parität, 1 Stop-Bit konfiguriert. Verkabelt mit EIB-Y(St) Y 2x2x0,8 mm² (eine Ader ungenutzt), terminiert mit 120 Ohm.

            Meinst du dies mit den Bus-Einstellungen?

              ja!

              die Geräte können einen höheren Datendurchsatz, was bei entsprechen kurzer Abfragezeit (!??) und Anzahl abgefragter Register (!??) notwendig sein kann.

              Ob bei der kurzen (!??) Strecke ein Terminator notwendig ist weiß ich nicht, glaube eher nicht.

              Also nochmal

                Wenn ich richtig liege, bedeuten die "MBR Driver receive error" jeweils 7 = "not enough minimal data recevied" und 9 = "CRC error".

                Die Fehler bleiben auch bestehen, wenn ich nur noch einen Zähler am Bus lasse.

                Wenngleich der Fehler wohl außerhalb von ioBroker liegt: habt ihr noch Tipps, wie ich mich der Problemursache nähern kann?

                  Wenn ich richtig liege, bedeuten die "MBR Driver receive error" jeweils 7 = "not enough minimal data recevied" und 9 = "CRC error".

                  Die Fehler bleiben auch bestehen, wenn ich nur noch einen Zähler am Bus lasse.

                  Wenngleich der Fehler wohl außerhalb von ioBroker liegt: habt ihr noch Tipps, wie ich mich der Problemursache nähern kann?

                  @sven79 Kenne den Tasmota Konverter nicht. Nutze für solche Sachen USRIOT oder Waveshare Teile. In der WLAN Bastler Liga läuft bei mir ein SDM120 mit einem USRIOT USR-WIFI232-A2 WLAN Modul mit einem RS485 TTL Konverter seit geraumer Zeit unauffällig, siehe https://forum.iobroker.net/topic/55710/sdm120-sdm72-sdm630-modbus-rs485-stromzähler-w-lan-iobroker/4?_=1678470143118

                  Hast Du einen RS485 <-> USB Stick? Den würde ich mal testweise anschließen, um den Tasmota Konverter auszuschließen.
                  Wenn es dann immer noch Probleme gibt, die Datenabfrage "ausräumen" bis kein Fehler mehr kommt. Vielleicht ist es ein einzelnes Datum, welches die Probleme verursacht.

                  Bei 3 Zählern hätte ich auch die höchste verfügbare und funktionierende Baudrate gewählt, um möglichst viele Daten über den Bus zu bekommen.

                    Die Zähler können leider nur maximal 9600 Baud. Ich habe sie nun alle einzeln und 1:1 angeschlossen, nun geht's. Ich verstehe zwar nicht, wieso das monatelang ohne Änderungen im Verteilerkasten einwandfrei lief und nun plötzlich den Dienst quittierte, aber sei es drum.

                      nope!
                      zumindest der sdm72 kann 19200 . die anderen beiden habe ich nicht.

                      kein Support per PN! - Fragen im Forum stellen - es gibt fast nichts, was nicht auch für andere interessant ist.

                        Wenn ich richtig liege, bedeuten die "MBR Driver receive error" jeweils 7 = "not enough minimal data recevied" und 9 = "CRC error".

                        Die Fehler bleiben auch bestehen, wenn ich nur noch einen Zähler am Bus lasse.

                        Wenngleich der Fehler wohl außerhalb von ioBroker liegt: habt ihr noch Tipps, wie ich mich der Problemursache nähern kann?

                        @sven79 Moin, kannst du mir vielleicht verraten, wie du das gemacht hast? Ich habe eine MAX3485 an einem NodeMCU gehängt und Modbus über Tasmota versucht. Ich bekomme nur ein "Done" zurück, sonst nichts. Egal wie viel Logging ich anmache. Hab jetzt 3 x den Aufbau, bei jedem das gleich Problem. Komplett keine Response.

                        NUC i5 mit Proxmox - KVM für ioBroker
                        Rest in Docker. z.B. KNXD, Pi-Hole, MySQL, Grafana, PostgreSQL, Wiki.js, Prometheus, Loki.

                        KNX mit GIRA Homeserver, aber auch Shelly´s und Zigbee
