  • Page 97 Description of application and parameters Application program With an actuation of the 1st or 2nd button a telegram with a predefined value is sent out. The application differentiates here between whether the 1st or 2nd button is actuated. Parameter General parameter Setting options Comments –...

  • Page 99 Description of application and parameters Application program When actuating and/or releasing the buttons, two telegrams with predefined values are sent from two different communication objects. In each case, the application makes a separate set of parameters and communication objects available for the 1st and the 2nd button. The application makes it possible, for example, to send out a switching function and a floating point value when actuating one side of the button and to assign an additional "button-oriented"...

  • Page 102 Description of application and parameters Application program When a button is actuated a predefined light scene number is called up. In each case, the application makes a separate set of parameters and communication objects available for the 1st and the 2nd button. The application makes it possible to call up a light scene via one button side while the other button side can be assigned with a further "button-oriented"...
  • Page 103 Description of application and parameters Application program Different switching processes are triggered with each new actuation of the 1st or 2nd button. For example: ■ First actuation (2nd button) switches lamp 1 on. ■ Second actuation (2nd button) switches lamp 1 off and lamp 2 on. ■...

  • Page 105 Description of application and parameters Application program Via the "Cyclic telegram" application and after receipt of a telegram on the "Input" object, a telegram with the same volume is cyclically sent out on the "Cyclic output" object. The object types for "Input" and "Output" can be collectively parameterised for the different applications. The times for cyclic sending on the "Output"...
  • Page 106 Description of application and parameters Application program The "Priority" application has 3 communication objects, a 1-bit object "Switch input", a 2-bit object "Input priority" and a 1-bit object "Output". The telegrams received on the "Switch input" are transferred to the "Output" depending on the state of the "Input priority" object. The 2-bit object "Input priority"...

The bit size can be freely assigned with the "Not assigned"...
  • Page 109 Description of application and parameters Application program With the "Staircase lighting" application, switching telegrams or value telegrams can be provided with a switch-off delay. Depending on the parameterisation, the application shows different communication objects: – a 1-bit object for input and output If an ON telegram is received via the "Input/Output"...
  • Page 110 Description of application and parameters Application program Telegrams can be received via the "Input" object using the "Delay" application. The telegrams received are sent out on the "Output" object with a set delay time. The object types for "Input" and "Output" can be collectively parameterised for the different applications.
  • Page 111 Description of application and parameters Application program Up to eight input values can be compared with each other using the "Min/max value transducer" application. The application can output the highest input value, the smallest input value or the average of all input values on the output. The size of the input objects, and with it also the size of the output object can be adapted for the most diverse applications.
  • Page 112 Description of application and parameters Application program With the "Threshold value / Hysteresis" application, value telegrams can be received on an input communication object and compared with threshold values specified in the device. Predefined values are sent out on the "Output" communication object if the upper threshold is exceeded or the lower threshold drops below the set value.
  • Page 113 Description of application and parameters Application program With the "Light scene actuator" application it is possible to call up scenes that are stored in the device via the receipt of a scene number on the 1-byte communication object "Scene call-up". A maximum of eight scenes with up to eight actuator objects can be created.
