Description

The FB_Impulszaehler function block counts transmitted pulses using edge detection and briefly displays each detected pulse via an internal timer. Realistic contact mapping is achieved using normally closed ( #NO_13_14 ) and normally open ( #NC_21_22 ) contacts, which are only active when the virtual enable inputs are set. The block offers reset, deactivation, and diagnostic functions.

Note: This logic is designed as a template. It must be reviewed, adjusted, and approved by qualified personnel before productive use. Incorrect integration may result in incorrect counting or unwanted switching behavior.

How it works
Reset

#Reset resets the counter ( #Count ), edge detection ( #risingEdge , #prevImpulse ), and the extension timer. The block restarts from scratch.

Disabled

If #Enable is not active, the outputs remain inactive. The block does not report any errors; the status indicates a neutral state.

Pulse detection

Rising edges of the input signal #Impulse are detected by comparing them with the previous state ( #risingEdge ). With each rising edge, the counter #Count is incremented and the extension timer ( #pulseTimer ) is started, giving the pulse a defined visibility duration.

Contact logic

The simulated contacts reflect the state of the extension timer, only if the corresponding enable inputs are set:

  • #NO_13_14 (normally closed) is active if #Input_13 is set and the pulse extension timer is set ( #pulseTimer.Q ).
  • #NC_21_22 (normally open) is active when #Input_21 is set and no pulse is visible (inverted).
Technical details
  • Inputs: #Enable , #Reset , #Impulse , #Input_13 , #Input_21
  • Internal logic: Edge detection via #prevImpulse , pulse extension with #pulseTimer
  • Counter: #Count – counted number of rising edges
  • Outputs: #NO_13_14 (normally closed when pulse is visible), #NC_21_22 (normally closed when no pulse is present)
  • Status & Diagnosis: #Error , #Status , #DiagnosticCode
  • Delay: T#100ms to visualize individual pulses
  • Modes: Reset, disabled, running
Possible applications
  • Pulse counting for sensors, flow measurement or switching operations
  • Extended display of individual pulses for better evaluation
  • Simulation of contact states via virtual release inputs
  • Integration into diagnostic or control systems for event counting

Note: Before productive use, a technical inspection and approval by qualified personnel is required.
