7.2 TARGETS
•
Description of problem: Module hardware failure detected.
•
How often the test is performed: Module dependent.
•

Latched target message: No.
•
Description of problem: A data item in a configurable GOOSE data set is not supported by the B90 order code.
•
How often the test is performed: On power up
•
What to do: Verify that all the items in the GOOSE data set are supported by the B90. The EnerVista UR Setup soft-
ware will list the valid items. An IEC61850 client will also show which nodes are available for the B90.
