Hi to all,
can ewon export a XML Configuration File describing the readable and writable tags by OPC UA protocol?

Thanks
Hi,

No, this is no possible with eWON. All you can get as a file is the Tags list (var_lst.csv).
By the way, this is the first time I hear that. What OPCUA software requires this XML file?

On the other hand, I am wondering why you need such a thing as the OPCUA protocol features a discovery command for browsing all data available.

Hi Simon,
I'm trying to connect from a siemens plc that I use as a client OPC UA.
The problem of the xml file is solved, but I still can not connect to ewon via OPC UA.
The problem now seems to be this:

"Check the permissible buffer size. The client provides 8192 bytes. The server must accept this value."

Is there a way to set or accept this size of the communication buffer?

Thank you very much
Hi,

First time I see such an error message...
There is no way to configure "a buffer size" in the Flexy.

What Siemens PLC model are you trying to connect ?
