I want to use the new Mango M2M2 in my home automation system in order to "talk" with my Siemens S7-226 PLC. Since I did not found a direct integration, I've installed the Siemens OPC server component. Unfortunately, I do not succeed in configuring the OPC server in Mango M2M2.

Whenever I want to register it as datasource, I enter all data (username, password, servername, ...) but I can not select the OPC server installed on that server from the listbox. Probably I am doing something wrong overhere.... can somebody help me out please?

I am using the latest M2M2 binary (found on this website) together with the OPC DA module (version 1, I belive).

Kind REgards,
