Timespan Compare 1Ch

The Timespan Compare 1Ch compares the input value with a reference value and returns the result of this comparison operation. A timespan with a resolution of 1 ns is supported as an input. The operator, the reference value and the count mode can be configured individually.

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

• Operator: specifies whether the input value should be greater than, greater than or equal to, less than or equal to, less than or not equal to the reference value.
• Reference: Reference timespan for the comparison operation.
• Count Mode: Mode of the result counter.
  OnChange: The counter counts every time the result changes to TRUE.
  Cyclic: The counter increments every cycle when the condition is TRUE.
• Use Absolute Values: If the checkbox is checked, the absolute value of the input signal is used.

Output values

• Operation Out: Result of the comparison operation.
• Count: Incremented when the output value is TRUE. The behavior depends on the parameter Count Mode.
• 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 Timespan Compare 1Ch algorithm, the following HMI controls are available for generating an Analytics Dashboard:

1. The Table Control visualizes all output values: Operation Out, Count, Last Event.

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