Siemens Server Interface

[Michael_Johannsen]

Hi.

Does anyone have tried to work with Siemens Server interfaces with OPC ua

I can easy create tags, just like when creating tage direct in the DB also woth OPC ua.

But when making UDT all the tags from the Server interface get a ongoing number.
I can not see how to make multiply UDTs when the tags only have number the tell them apart.

Siemens S7-1200 OPC UDT error

Thanks for investigating Kevin. As per Matthew’s post, I think that what you have described is only currently possible with the S7-1500 which has more OPC-UA options. Is there a plan for adding the custom address space functionality/new attribute to ignition? I have only tested 2 free OPC-UA clients but they were both able to read the whole structures from the S7-1200. Cheers

If you dig into the Eclipse Foundation's Milo Project, you will find that such features are under active development. My gut sense says not too far off.

However, Milo v1 might be a breaking change for the Ignition v8.1.x series. We'll see.
