Hello,

With reference to Part 13: Aggregates OPC UA Specifications I have the following questions

The Aggregates(Minimu,Maximum) evaluated using the raw data specified in sections A.1.1 (Historian1), A.1.2(Historian2) and A.1.3(Historian3) has the status code as Partial only for one of the aggregate intervals specified below.

Could you please justify why this aggregate interval is alone evaluated as partial and why not other intervals?

Good, Partial

Please check again - I see multiple intervals with a status of Partial?

For Minimum, where your example comes from, each of the three examples has multiple partial intervals defined. You will see this is the same for the Maximum aggregate. See clause 5.3.3.2 for the partial bit information.
