4.2.4.1.6 Push-button function 2-channel operation
In some situations it is desirable to control two different functions with a single button-press and
to transmit different telegrams, i.e. to operate two function channels at a time. This is possible
with the "2-channel operation" function.
For both channels, the parameters "Function channel 1" and "Function channel 2" can be used
to determine the communication object types to be used. The following types are available for
selection…
-
Switching (1 bit)
-
Value transmitter 0 … 255 (1-byte)
-
Value transmitter 0 … 100 % (1-byte)
-
Temperature value transmitter (2 bytes)
The object value the device is to transmit on a button-press can be selected depending on the
selected object type. With "Switching (1 bit)", it is possible to select whether an ON or an OFF
telegram is transmitted on the press of a button. Alternatively, the object value can be switched
over (TOGGLE) and transmitted. The configuration as "Value transmitter 0 … 255 (1 byte)" or
as "Value transmitter 0 … 100 % (1 byte)" permits entering the object value freely within a range
from 0 to 255 or from 0% to 100%. The "Temperature value transmitter (2 bytes)" permits
selecting a temperature value between 0°C and 40°C.
In this case, the adjustment of the object value on a long button-press is not possible as the
determination of the actuation length is needed for the adjustable operation concepts.
Unlike the other functions of the push-button, it is possible for the device buzzer to execute the
function "Telegram acknowledgement". Here, an acoustic signal sounds for approx. 250 ms
each time a telegram is transmitted (see page 88).
Operation concept channel 1 or channel 2
In this operation concept, exactly one telegram will be transmitted on each press of a button.
-
On a brief press the device transmits the telegram for channel 1.
-
On a long press the device transmits the telegram for channel 2.
Figure 10: Example of operation concept "Channel 1 or Channel 2"
The time required for distinguishing between a short and a long operation is defined by the
parameter "Time between channel 1 and channel 2". If the button is pressed for less than the
configured time, only the telegram to channel 1 is transmitted. If the length of the button-press
exceeds the time between channel 1 and channel 2, only the telegram to channel 2 will be
transmitted. This concept provides the transmission of only one channel. To indicate that a
telegram has been transmitted, the device buzzer outputs a tone for approx. 250 ms in the
"Telegram acknowledgement" setting.
