Function block LEDGEN
•
Handles an external acknowledge signal as source to acknowledge the LEDs.
•
Generates an additional pulse for general purposes whenever the LEDs are
acknowledged by the operator.
•
Generates a pulse whenever a new LED signal occurs. It may be used to
trigger an acoustical alarm.
•
Handles the timer
tReset
and
tMax
for the LED operation mode 'LatchedReset-
S'.
Function block GRP1_LED1 to GRP3_LED15
•
The 15 LEDs on the right side of the LCD can indicate in total 45 alarms,
warnings or other signals to the operator. They are organized in three groups 1
to 3.
•
Each signal group belongs to one function block.
•
Each LED illuminates in one of the three colors: RED, YELLOW or GREEN.
•
The organization of flashing, acknowledgment and group selection is done
directly between the function blocks and the basic LHMI keys, the
'Multifunction' key [a] to toggle between the three groups or the 'Clear' key [b]
to acknowledge or reset the LEDs.
•
Only the programming of the signals is needed for the LEDs.
•
The operation mode of the LEDs is defined in Parameter Setting tool.
Function block FNKEYMD1 to 5
•
Every function key has an own FNKEYMD function block.
•
The 5 function keys on the left side of the LCD [B] can be used to process
demands.
•
The function block handles the signal for the LED included in the key as input
signals.
•
The LED signal of the key is independent of the key function and must be
programed to process demands.
•
The function block handles the operators command when the key is pressed as
output signal.
