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
This chapter describes in general the configuration of switching actions, using an
example for a device with 2 ports. Models with only one port must be abstracted.
Depending on the measured Current and the measured sensor values, switching actions
can be triggered. During operation, the actions configured for crossing the limits are ex-
ecuted. For example, when a value moves from the range "above max value" inside the
range "below max value", the action defined for "below max value" is performed. 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.
