A: Yes. UNS support needs to be implemented in terms of integration with the other application. The Plan 4 support custom integration where you can extend the data via Python interfaces and do custom implementation and decisions based on the topics and data.

We have done SCADA Implementation for customers using Modbus interfaces.

Regarding the SLA, for support we give the default 24 hour response and 48 hour resolution over email.

Hope this helps.
