Detect Value Change 1Ch

Detect Value Change 1Ch 1:

The Detect Value Change 1Ch detects and counts changes in numeric input values.

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

  • Tolerance: The tolerance refers to the input value of the last detected value change. If the input value is outside this tolerance, a value change is detected.

Output values

  • Value Changed: TRUE, if a value change was detected, otherwise FALSE.
  • Count: Count up every time Boolean Switch is TRUE.
  • 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 Detect Value Change 1Ch algorithm, the following HMI controls are available for generating an Analytics Dashboard:

1. The SingleValue control visualizes the output values Count and Last Event.

Detect Value Change 1Ch 2:

2. The Table Control and Multivalue Control visualize all output values.

Detect Value Change 1Ch 3:
Detect Value Change 1Ch 4:
Detect Value Change 1Ch 5:

Alternatively, customer-specific HMI controls can be mapped using the Mapping Wizard.
