RS 485 / Modbus 8fach Relais ET40A08 einbinden

[juppy_jupp]

Hallo zusammen,

ich versuche in meiner FHEM Umgebung ein 8fach Relais vom Typ ET40A08 über Modbus einzubinden.
Das Relais hat ein Ethernet IF das man über eine Web GUI konfigurieren kann, siehe Bild im Anhang.
Leider finde ich keinerlei Doku dazu.
Aber über TCPUDPdmp kann ich mit folgenden HEX Werten einzelne Relais Kanäle schalten, dazu muss ich aber das Relaismodul von Modbus Slave auf TCP Client umstellen:

Relais 0 ein:
01 06 00 00 01 00 88 5a

Relais 0 aus:
01 06 00 00 02 00 88 aa

Relais 1 ein:
01 06 00 01 01 00 D9 9A

Relais 1 aus:
01 06 00 01 02 00 D9 6A


Ich hab ein Modbus Device angelegt und den ersten Eingang definiert mit folgender Konfig:

attr Relais obj-h0-reading Relay.1
attr Relais obj-h0-set 1
attr Relais obj-h0-showGet 1
attr Relais room System
attr Relais verbose 5

Wenn ich das Device verbinde bekomme ich folgenden Logoutput:

Ohne bswapRegs waren die beiden Register Bytes noch vertauscht.
Jetzt bekomme ich aber im "Send" exakt den erwarten HEX Wert wenn ich ein set Relay.1 on/off absetze.
Nur am Relais tut sich nix, der entspr. Eingang wird nicht geschaltet.

An dem Punkt komme ich nicht mehr weiter und benötige eure Hilfe.

Hallo,

es geht !

Ich hab auf FHEM Seite auf TCP umgestellt und irgendwie ist auch die Konfiguration des Relais nicht ganz einfach. Zum Wirksamwerden muss man es nach jeder Änderung kurz von der Stromversorgung trennen.

Hier die nun laufende FHEM Konfig. Ich hab bis dato zum Testen erstmal nur 4 Relaisausgänge definiert.
Die Readings werden auch automatisch nach der ersten Aktivität angelegt. Die Konfig auf dem Relais ist unverändert wie im Screenshot vom ersten Thread.

2:off     Relais aus

4:excl    Diese Relais an, alle anderen aus
5:1s      Relais für 1 sec. an

Im Netz hab ich dazu weitere Infos gefunden:

01 06 00 01  02 XX  XX XX - Relais1 AUS
01 06 00 01  03 XX  XX XX - Relais1 TOGGLE

01 06 00 01  06 0A  5B AD - Relais1 10s IMPULS und alle anderen AUS

Wie ich die drei verbleibenen möglichen Stati noch definieren kann, muss ich noch rausfinden.
