Figure 13: Programmable LEDs on the right side of the LHMI
All the programmable LEDs in the HMI of the merging unit have two colors, green
and red. For each LED, the different colors are individually controllable.
Each LED has two control inputs, ALARM and OK. The color setting is common for all
the LEDs. It is controlled with the Alarm colour setting, the default value being "Red".
The OK input corresponds to the color that is available, with the default value being
"Green".
Changing the Alarm colour setting to "Green" changes the color behavior of the OK
inputs to red.
The ALARM input has a higher priority than the OK input.
Each LED is seen in the Application Configuration tool as an individual function
block. Each LED has user-editable description text for event description. The state
("None", "OK", "Alarm") of each LED can also be read under a common monitored
data view for programmable LEDs.
