Edge Counter 1Ch

The Edge Counter 1Ch counts the amount of raised events. An event is raised when the signal of the input channel passes the configured edge at a specific threshold.

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

• Type of the edge: Specifies whether the edge counter should respond to a rising or falling edge.
• Threshold: Threshold of the signal at the respective edge. The event is triggered when the signal passes this threshold.
• Tolerance (optional): Tolerance value for the Equal / NotEqual comparisons.

Output values

• Edge: Indicates TRUE at the time the event is triggered, otherwise FALSE.
• Count: Counts the number of triggered events.
• 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 Edge Counter 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.

2. The Table Control or Multivalue Control visualizes all output values: Edge, Count, Last Event.

Alternatively, custom HMI controls can be mapped in the Edge Counter 1Ch algorithm using the Mapping Wizard.
