  • Clause Reference set to Part 8 Clause 8.1.2.2

Clause 8.1.2.2 states: "Enumerated values outside the standardized range but within the MMS integer size shall be assumed to be value extensions and shall not cause a protocol error".
So we have to add this to the conformance test

Richard's reference follows:

The size of the MMS data type shall be the minimum size required to contain the maximum standardized value.

The size of the integer is 8 bits for all currently published enumerations.

The issue is not only for the scope of fixed-length GOOSE tests, but also for BER-encoded GOOSE tests.
Additionally, the test procedure shall indicate that the EnumType in the SCD is indicating ord values that are negative, or bigger than 129,...
