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 display [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.
•
The functions are activated whenever a key is pressed the first time. The
corresponding text elements for the five keys appear on the left side of the display.
No execution of the function is done. So the first push is used to activate the
presentation only.
•
The next key push is handled as activate function and the output signal of the
function block is set.
•
The operation mode of the function key is defined in Parameter Setting tool
(pulse, toggle).
Parameter Setting tool and function block configuration
The operation mode of the function keys and the LEDs must be defined per key and
LED in Parameter Setting tool.
The function key can operate as:
•
Pulsed signal
•
Each push forces a pulse of a configured time.
•
The pulse time can be set in Parameter Setting tool.
•
The default pulse time is 200 ms.
•
Toggle signal
•
Each push changes the state of the signal: OFF-ON-OFF-ON-OFF...
•
The default position after power up or reset is OFF.
•
Menu shortcut
•
When pressing a key configured for that purpose, the function key panel is
hidden and LHMI opens directly in the configured menu.
