4.2.4.6.4 "Value transmitter" function
For each rocker or each button with the function set to "1-byte value transmitter" or "2-byte
value transmitter" the ETS indicates a corresponding object. On the press of a button, the
configured value or the value last stored internally by a value change (see below) will be
transmitted to the bus. In case of the rocker function, different values can be configured or
varied for both actuation points.
The status LEDs can be configured independently (see chapter 4.2.4.7.1. Functions of the
status LED).
Value ranges
The "Function" parameter determines the value range used by the push-button.
As a 1-byte value transmitter, the push-button sensor can optionally transmit integers from 0 …
255 or relative values within a range of 0 … 100 % (e.g. as dimming value transmitter).
As a 2-byte value transmitter, the push-button sensor can optionally transmit integers from 0 …
65535, temperature values within a range of 0 … 40 °C or brightness values from 0 … 1500 lux.
For each of these ranges, the value that can be transmitted to the bus for each actuation of a
rocker or button is configurable.
Adjustment by means of long button-press
If the value adjustment feature has been enabled in the ETS, the button must be kept
depressed for more than 5 seconds in order to vary the current value of the value transmitter.
The value adjustment function continues to be active until the button is released again. In a
value adjustment, the push-button sensor distinguishes between the following options...
-
The "Starting value in case of value adjustment" parameter defines the original starting
value for the adjustment. Adjustment can begin from the value configured in the ETS, from
the final value of the last adjustment cycle or from the current value of the communication
object, with the last option not being available for the temperature and brightness value
transmitter.
-
The parameter "Direction of value adjustment" defines whether the values will always be
increased ("upwards"), always reduced ("downwards") or alternately increased and
reduced ("toggling").
-
For the value transmitters 0 … 255, 0 … 100 % and 0 … 65535, the "step width" by which
the current value is to be changed during the value adjustment can be specified. In case of
the temperature and the brightness value transmitter, the step width specifications (1 °C
and 50 lux) are fixed.
-
The parameter "Time between two telegrams" can be used in connection with the step
width to define the time required to cycle through the full respective value range. This value
defines the time span between two value transmissions.
-
If, during the value adjustment, the push-button sensor detects that the preset step width
would result in the limits being exceeded with the next telegram, it adapts the step width
once in such a way that the respective limit value is transmitted together with last telegram.
Depending on the setting of the parameter "Value adjustment with overflow", the push-
button sensor stops the adjustment at this instance or inserts a pause consisting of two
levels and then continues the adjustment beginning with the other limit value.
