I’d like to integrate the Relay LAN Board DS2824 from Robot Electronics into OpenHAB 3.
It has 24 relays (capable for 230V / max. 16A) that can be managed via LAN.
There seem to be four possible modes to manage the board:
TCP / IP command set (like: “IP Port SR 1 on” to set the first relay on or “IP Port GR 1” to get the status of the first relay)
Binary command set (setting the comands by bytes like 0x30)
AES binary command set (like 2., but including encryption)
modbus commands.
I suppose it would be the most easy for beginners to use the TCP / IP commands with the http-bindings, but I still find no tutorial where and how to put the commands in the binding configuration.
Can somebody pls give some hints?
Thank you very much!
Markus
PS: You might find the documentation about the mentioned board here in a zip-file: dScript software
Thank you very much James - I think I will inform me (in future) about Modbus TCP and trying to get it work starting from your hint… the problem is: I have not much idea about Modbus and few time to get it work, so this must wait a little (although it might be the much better or solid way).
Thank you, too, Wolfgang: I looked for an TCP/UDP binding, but still did not find any in the list of my installation…
