4.2.4.6.6 2-channel operation function
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 can be selected...
-
Switching (1 bit)
-
Value transmitter 0 … 255 (1-byte)
-
Value transmitter 0 … 100 % (1-byte)
-
Temperature value transmitter (2 bytes)
The object value the push-button sensor is to transmit on a button actuation can be selected
depending on the selected object type. The "Switching (1 bit)" type permits selecting whether an
ON or an OFF telegram is to be transmitted or whether the object value is be switched over
(TOGGLE) and transmitted on the press of a button.
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 in the other rocker and button functions, the application software assigns the "Telegram
acknowledge" function instead of the "Button-press display" function to the status LED. In this
mode, the status LED lights up for approx. 250 ms with each telegram transmitted. Alternatively,
the status LEDs can be configured independently .(see chapter 4.2.4.7.1. Functions of the
status LED).
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 push button-sensor transmits the telegram for channel 1.
-
On a long press the push-button sensor transmits the telegram for channel 2.
Figure 70: 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
