3.16.6.2 Functionality
The T_DIR function evaluates enumerated data of the FAULT_DIR data attribute
of the directional functions. T_DIR can only be used with GOOSE. The DIR input
can be connected to the GOOSERCV_ENUM function block, which is receiving the
LD0.<function>.Str.dirGeneral or LD0.<function>.Dir.dirGeneral data attribute sent
by another device.
In case the GOOSERCV_ENUM function block does not receive the value from the
sending device or it is invalid, the default value (0) is used in function outputs.
The outputs FWD and REV are extracted from the enumerated input value.
