Which OPC DA version is supported by ABB Freelance?
There are 2 major OPC DA version: 2.05a and 3.0. I suppose Freelance support the one of them or both.
Where can I check the technical information? I couldn't find reasonable information on ABB Library.

- Custom Interface (DA) 2.0
- Automation Interface (DA) 2.0A
