Threshold Classifier 1Ch

Threshold Classifier 1Ch classifies the input values into three different classes: OK, Warning and Alarm according to the configured thresholds.

Optionally, a Boolean signal can be selected for the Enable Execution input so that the algorithm is only active if the value of the selected signal is TRUE.

Configuration options

• Level Ok / Warning: Input values that are less than the configured threshold are classified as OK; input values that are equal to or greater than the configured threshold are classified as Warning.
• Level Warning / Alarm: Input values that are less than the configured threshold are classified as Warning; input values that are equal to or greater than the configured threshold are classified as Alarm.
• Tolerance (optional): Tolerance value for the Equal / NotEqual comparisons.

Output values

• Class: Indicates the class to which the input values belong.
• Last Event Warning: Indicates the time of the last triggered warning event → the event can be dragged and dropped into the scope chart to display it as a trigger-event.
• Last Event Alarm: Indicates the time of the last triggered alarm event → the event can be dragged and dropped into the scope chart to display it as a trigger-event.

Standard HMI Controls

For the Threshold Classifier 1Ch algorithm, the following HMI controls are available for generating an Analytics Dashboard:

1. The TrafficLight Control visualizes the output values Class, Last Event Warning and Last Event Alarm as well as the input value of the data.

2. The MultiState Control visualizes the Class output value, optionally with a smiley.

3. The Tachometer Control visualizes the input value including the configured limit values.

4. The Radial Gauge Control visualizes the input value including the configured limit values.

5. The Table Control or Multivalue Control visualizes all output values: Class, Last Event Warning Last Event Alarm.

Alternatively, customer-specific HMI controls can be mapped in the Threshold Classifier 1Ch algorithm using the Mapping Wizard.
