How to set up DLMS director to read many objects in one request?

Or it's not possible. According to PDU syntax from https://cyamon.com/Syntax/pdu_syntax.html
only _SetRequest has _SetRequestWithDataBlock,
but _GetRequest do not have something like _GetRequestWithDataBlock
very very strange... maybe I'm missing something?

Hi,

I don't know if "Multiple references" is set for the client-side, but it's not set for the negotiated conformance. This means that you can read only one value at the time.

Check that "Access" and "Multiple references" are checked on the "Supported Services" tab.
