Fig. 16 – Example of Threshold comparation logic.
It is possible to configure the following:
➢ Name of the logic: this is the name whom it will be reported on the messages SMS, Mail and MQTT.
➢ Used measurements: [Edit] to select one or more measurements jointed to this logic.
➢ Types of compare:
• Less then: this logic is activated when the measurement value is less than the lower threshold
(less the hysteresis value) and it will be deactivates when the measurement value is greater
than the lower threshold (plus the hysteresis value). Example: threshold = 4.0 and hysteresis
= 0.2. The logic is activated with a value less than 3.8 and deactivated with a value greater
than 4.2.
• More than: this logic is activated when the measurement value is more than the upper
threshold (plus the hysteresis value) and it will be deactivates when the measurement value
is less than the upper threshold (less the hysteresis value). Example: threshold = 4.0 and
hysteresis = 0.2. The logic is activated when the value is more than 4,2 and deactivated when
the value is less than 3,8
• Within: this logic is activated when the measurement value is greater than the lower
threshold (plus the hysteresis value) and lower than the upper threshold (less the hysteresis
value) and deactivates when the measurement value is lower than the lower threshold (less
the hysteresis value) and higher than the upper threshold (plus the Hysteresis value).
Example: threshold = 4.0 and hysteresis = 0.2. The logic is activated when the value is within
3.8 and 4.2 and it is deactivated when outside.
• Outside: this logic is the opposite of the Within logic. Example: threshold = 4.0, hysteresis=
0.2. Logic is active when the values is less than 3.8 and more than 4.2 and then it is
deactivated when inside.
➢ Activation modality:
• Single measure: this logic is activated considering the measurement selected in Used
measures.
• At least one measurement (OR condition): this logic is activated considering at least one of
the measurements selected in Used measures.
• All measures (AND condition): this logic is activated considering the whole set of
measurements selected in Used measures.
➢ Upper threshold: it is the value of the upper threshold; it is not available when the Less than logic has
been chosen.
