Issue

As I understand a report is to be issued ,whenever an internal event due to any of the trigger options mentioned in the report control block occurs. And the trigger options applying to each data attribute is specified in 7-3. as mentioned in NOTE 2.(page 88)
"
NOTE 2 With the specification of the common data classes in IEC 61850-7-3, the trigger option applying to
a specific DataAttribute is defined."

But I find that there are many attributes with missing trigger option in 7-3.Why is this so and how reporting is to be handled in this case?

For example,lets say I have a dataset configured with only a single FCDA (XCBRxxx.ST.Pos.t)and in my Report Control Block, I have TrgOp=dchg.In this case is the server supposed to send any report at all ?

Proposal

A statement similar to "Data attributes with empty trigger options will not trigger any reports other than that due to GI & integrity poll" may be added .
