Threshold String Classifier 1Ch

The Threshold String Classifier 1Ch algorithm classifies the input values into three different classes according to the configured thresholds. The class names (output string) can be configured individually as String 1, String 2 and String 3.
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 1 / 2: Input values that are less than the configured threshold are assigned to the first class; input values that are equal to or greater than the configured threshold are assigned to the second class.
- Level 2 / 3: Input values that are less than the configured threshold are assigned to the second class; input values that are equal to or greater than the configured threshold are assigned to the third class.
- String 1: Name of the first class.
- String 2: Name of the second class.
- String 3: Name of the third class.
- Tolerance (optional): Tolerance value for the Equal / NotEqual comparisons.
Output values
- Output String: Indicates the class to which the input values belong.
- Last Event: Indicates the time of the last triggered 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 String Classifier 1Ch algorithm, the following HMI controls are available for generating an Analytics Dashboard:
1. The TrafficLight control visualizes the output values Output String and Last Event as well as the input value of the data.

2. The SingleValue control visualizes the output value Output String.

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: Output String, Last Event.



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