3.10.3.2 Functionality
The T_HEALTH function evaluates enumerated data of “Health” data attribute. This
function block can only be used with GOOSE.
The IN input can be connected to GOOSERCV_ENUM function block, which is receiving
the LD0.LLN0.Health.stVal data attribute sent by another protection relay.
The outputs OK, WARNING and ALARM are extracted from the enumerated input value.
Only one of the outputs can be active at a time. In case the GOOSERCV_ENUM function
block doesn't receive the value from the sending relay or it is invalid, the default value (0)
is used and the ALARM is activated in the T_HEALTH function block.
