Description

Leak detection for closed systems – ideal for training, commissioning, optimization, and system planning. Choose between two versions:

  • Variant A Basic – compact leak detection (slim, quick to integrate)
  • Variant B Industry 4.0 – with event history (FIFO), diagnostic structure, error code, maintenance recommendation and reset

Note: All modules are designed as a learning and optimization tool and are not approved for live operation. They must be reviewed by qualified personnel before productive use.

Variants at a glance
Variant A – Basic
  • Compares Durchfluss with Schwelle and checks valve states.
  • Sets leakage to TRUE when flow > threshold and all valves are closed.
  • Clear status text for “leakage”, “plausible flow” or “normal state”.
  • Minimal resource requirements, quick integration into existing projects.
Variant B – Industry 4.0 (with history & diagnosis)
  • FIFO history of recent events (timestamp, flow, valve states).
  • Diagnostic structure with fields for LeckageErkannt , Zeitstempel , Durchfluss , Schwelle , VentileZustand , Fehlercode and StatusText .
  • Leakage counter & maintenance logic: maintenance is recommended from a defined frequency (e.g. “check lines and seals”).
  • Manual reset of the meter via LeckageReset .
  • Ideal for HMI/SCADA : clearly structured data points, easy to visualize.
How it works
Valve testing

Up to 10 valves are checked in a loop. If no valve is open, "All valves are closed."

Leakage detection

If Durchfluss > Schwelle AND all valves are closed, a leak is signaled.

  • Variant A: Sets Leckage and StatusText .
  • Variant B: Additionally set diagnosis , push history , log new event , increase counter .
No leak / plausible flow
  • No leak: flow ≤ threshold ⇒ normal condition.
  • Plausible: Flow > threshold, but at least one valve open ⇒ no leak, plausible operation.
Maintenance & Reset (Variant B)
  • From a configurable frequency (e.g. ≥ 5 events) MaintenanceRecommended is set.
  • LeckageReset resets the counter and removes the maintenance recommendation.
Interfaces (inputs/outputs)
  • Inputs : Ventile[1..10] (BOOL array), Durchfluss (REAL), Schwelle (REAL), (Variant B) LeckageReset (BOOL), AktuelleZeit (DT)
  • Exits :
    • Variant A: Leckage (BOOL), StatusText (STRING)
    • Variant B: Diagnose (structure), LeckageZaehler (INT), WartungEmpfohlen (BOOL), EmpfohleneMaßnahme (STRING), LeckageHistorie[1..10] (structure)
compatibility
  • Siemens S7-1200 / S7-1500
  • TIA Portal V13 and higher (simulation and HMI connection recommended from V16)
  • Tested with PLCSIM (recommendation for commissioning tests)
Scope of delivery
  • .scl files:
    • FB_LeakageDetection (Variant A – Basic)
    • FB_LeakageDetection_40 (Variant B – Industry 4.0 with history & diagnosis)
  • Declarations, comments, structured data types.

The download link will be provided immediately after purchase.

HMI/SCADA notes (variant B)
  • Diagnostic tile: Leakage Detected, Error Code, Status Text, Timestamp.
  • Trend/Log: Display of the FIFO history (time/flow/valve pattern).
  • Maintenance: Warning symbol for MaintenanceRecommended , text from RecommendedAction .
  • Operation: Reset button for LeckageReset .
Support

I am happy to support you with:

  • Adjustment of thresholds, number of valves and history depth
  • Extension with additional sensors/feedback (e.g. pressure, temperature)
  • HMI visualization, diagnostic dashboards, alarming & maintenance concepts
  • Integration into existing TIA projects (SCL/DB/UDT structure)
