Time characteristics
Sensor for display of measuring values
In this application, the displayed value follows the actual value after a short delay.
Note:
Upon switch-on of the sensor or the Dupline bus, the actual sensor value is only reached after a time
elapse of 30 s. This time is needed by the system to calculate the value accurately.
Sensor as switching channel
The time characteristics of the sensors are here illustrated by the example of a temperature sensor: the upper
curve shows the room temperature, the curve in the middle shows the Disable address, and the lower curve
shows temperature sensor as switching channel.

1
:
The room temperature drops to the value entered for On > Limit, eg 21°C. Since no Disable Address
is entered, the object “Temperature sensor” switches the channel on.
t
2
:
The temperature reaches the value entered for Off < Limit, eg 17°C. Since a Disable Address is still not
entered, the channel assigned to the “Temperature sensor” object switches off.
t
3
:
The room temperature reaches the lower limit value again, and the object switches on.
t
4
:
The Disable Address (channel or flag) is activated, for example through a toggle switch.
t
5
:
Although the upper limit value is reached, the object does not switch the channel on, because the
Disable address is active.
t
6
:
The temperature sensor switching channel does not switch off, until the Disable address is deactivated.
