Functionality
The programmable function block FKEY is a simple interface between the panel and the
application. The user input from the buttons available on the front panel is transferred to
the assigned functionality and the corresponding LED is Enabled or Disabled for
indication. The behavior of each function key in the specific application is configured by
connection with other application functions. This gives the maximum flexibility.
Operation principle
Inputs L1..L16 represent the LEDs on the protection relay's LHMI. When an input is set
to TRUE, the corresponding LED is lit. When a function key on LHMI is pressed, the
corresponding output K1..K16 is set to TRUE.
