Configuration
Hysteresis Example:
A Hysteresis value prevents that too much messages are generated, when a sensor
value is jittering around a sensor limit. The following example shows the behavior for a
temperature sensor and a hysteresis value of "1". An upper limit of "50 °C" is set.
Example:
49.9 °C - is below the upper limit
50.0 °C - a message is generated for reaching the upper limit
50.1 °C - is above the upper limit
...
49.1 °C - is below the upper limit, but in the hysteresis range
49.0 °C - is below the upper limit, but in the hysteresis range
48.9 °C - a message is generated for underrunning the upper limit inclusive hysteresis
range

Port Switching

Depending on the measured Current and the measured sensor values, switching ac-
tions can be triggered. During operation, the actions configured for crossing the limits
are executed. For example, when a value moves from the range "above max value" in-
side the range "below max value", the action defined for "below max value" is per-
formed. In the case of device start, configuration or plug-in of the sensor, the actions
corresponding to the range in which the current temperature is located are switched.
Example with "Maximum value" of 65 °C, "Minimum value" of 25 °C and hysteresis of 3
°C. The dotted line shows the hysteresis.
Actions during configuration, device start or plugging in the sensor (for given example):
