View source for Dual Function on a single Call Button

{{AI}}


This application makes it possible to distinguish between short press or long press of a call button or DAK. <br>
If call button or DAK is released within 3 seconds it will do one call. If pressed and kept pressed for more than 3 seconds it will do a different call.<br>
In this way one call button or DAK can be used to activate two different calls or functions.<br>

{{Note|The DAK or call button used, should not be programmed in the DAK window at all. The destination for the call is programmed in the events used}}

==Input or DAK pressed==
Use an available [[UDP group]] as owner for the events. UDP 2 is used in this example.
Select [[Station_Input_or_Station_DAK_key_(Event_Type)|event type 30]], with subtype 1 for Turbine call button and master station DAK 1, subtype 11 for [[IP_Vandal_Resistant_Substation_TKIE|TKIE tamper proof station]] or Turbine input 1.
'''Event 1:''' - Start a 3 second (W30) timer related to number 9991, and write value 1 to [[User_Defined_Data_-_UDD|UDD]] index = physical number of station.

Action:
{|
|-
| $ST L%1.dir W30 L9991
|-
| WUDD %1.phy 1
|-
|}

==Input or DAK released before timeout==

Insert an event 30, with same owner and subtype, when change to OFF. This event will be triggered if button is released before timeout.
Actions:
 IF %udd(%1.phy)
 WUDD %1.phy 0
 $ST L%1.dir
 $CALL L%1.dir L102
 ENDIF<br>
Explanation: Reset UDD and stop timer if UDD is set, and call station 102.

[[CALL_SETUP|$CALL]] can only be used for station-to-station calls, but other commands can be used. A [[Ringing_group|ringing group]] call using [[SEND_MAIL|$SM]] can look like this:<br>
 $SM L%1.dir L6701 U100 NM18 GV U13<br>
It is also possible to simulate that a specific DAK is activated. The advantage is that every station can have its "own" programming done in the DAK window, instead of using a common destination. Note that a unused DAK is recommended to use. Example using DAK 10:
[[DIAL_DAK|$DIAL_DAK]] L%1.dir U10

So options are:
* Direct call: $CALL....
* Ringing group: $SM...
* Simulate DAK press: $Dial_DAK...

Note: [[DIAL_DIGITS|$DD]] is not recommended to use for this function, because repeated button presses during ringing or conversation might cause malfunction.

==Input or DAK kept pressed==

[[Event_Timeout_(Event_Type)|Event 21]] is triggered if button is not released within timeout. This is used to set up the second call function.<br>
Actions in the example below are:
 $SM L%1.dir L6701 U100 NM18 GV U13
 WUDD %1.phy 0<br>
Explanation: Starts ringing group 1 (6701) and sets UDD = 0.
