LED configuration alternatives

Functionality
The function blocks LEDGEN and GRP1_LEDx, GRP2_LEDx and GRP3_LEDx
(x=1-15) controls and supplies information about the status of the indication LEDs.
The input and output signals of the function blocks are configured with PCM600. The
input signal for each LED is selected individually using SMT or ACT. Each LED is
controlled by the GRPn_LEDx (n=1-3) function block that controls the color and the
operating mode.
Each indication LED on local HMI can be set individually to operate in 6 different
sequences; two as follow type and four as latch type. Two of the latching sequence
types are intended to be used as a protection indication system, either in collecting or
restarting mode, with reset functionality. The other two are intended to be used as
signalling system in collecting mode with acknowledgment functionality.
Status LEDs
There are three status LEDs above the LCD in front of the IED: green, yellow and red.
The green LED has a fixed function that presents the healthy status of the IED. The
yellow and red LEDs are user configured. The yellow LED can be used to indicate that
a disturbance report is triggered (steady) or that the IED is in test mode (flashing). The
red LED can be used to indicate a trip command.
Here is a typical configuration of the status LEDs:
