Siemens OZW672

[Sakson]

Hello,

someone tried to read data from Siemens OZW672? Despite the virtual input can not, because they can not text values.

I remember this device....do. you want to read out a Broetje heater?

[Sakson]

I have a boiler GEMINOX with PLC Albatros and web server OZW672. I would like to transmit the temperature from the boiler to the Loxone.

[Nobbi75]

Ah ok. I thought about this device for my broetje heater. Then i can not help.

Hello,

The OZW672 is a Webserver for Heatingssystems by Siemens, http://www.buildingtechnologies.siem...zw672_001.aspx

It can be able in Brotje or another Heating System´s with LPB/BSB Bus developed by Siemens.

You Need a OZW672 API for Correct Adress to Read the Data.

Search on Google by Keyword OZW672-API show many FEHM Treats.

Good Luck

Sorry for the bad English Scool for many many years ago ;-)

My English is too bad :-). API is not a problem, I have a manual siemens. I do not know how to get to PicoC.
API works like this:

I have the same Problem with Wolf Heater and ISM8i Modul, SPS Programming i can do but not C#, Perl, XML, or any other Web based Programming Language :-(

I must create a TCP/IP Objectserver for my RasPi (Loxberry) to grab the Data into a Database or XML.
