Description

The FB_Speed_Monitoring function block monitors a pulse frequency (e.g., from a speed sensor) and compares it with a specified setpoint ( #Setpoint ). The status is output via realistic contact mapping (normally closed contact #NO_13_14 , normally open contact #NC_21_22 ), with virtual inputs ( #Input_13 , #Input_21 ) acting as enable signals. The block recognizes reset and deactivation states and offers clear OK/alarm behavior.

Note: This logic is designed as a template. Before productive use, it must be integrated, tested, and approved by qualified personnel. Incorrect integration may result in incorrect status display or unexpected control behavior.

How it works
Reset

When #Reset is set, the block is put into a defined basic state: Normally closed contact is open (no run), normally open contact is closed (warning/alarm), status shows “Reset”.

Disabled

If #Enable is not active, both contacts remain inactive. The module does not report any errors and displays a neutral state.

Speed rating

The measured pulse frequency ( #PulseFreq ) is compared with the setpoint ( #Setpoint ). If it is greater than or equal to the setpoint, the condition is considered OK ( #rpmOK = TRUE).

Contact logic

The outputs follow the evaluation result taking into account the release inputs:

  • #NO_13_14 (normally closed) is active if #Input_13 is set and the speed ≥ setpoint.
  • #NC_21_22 (normally open) is active when #Input_21 is set and the speed is < setpoint (inverted).

The status is set to OK, errors are reset.

Technical details
  • Inputs: #Enable , #Reset , #PulseFreq , #Setpoint , #Input_13 , #Input_21
  • Internal state: #rpmOK – TRUE if actual frequency ≥ setpoint
  • Outputs: #NO_13_14 (open contact when OK), #NC_21_22 (close contact when undershot)
  • Status & Diagnosis: #Error , #Status , #DiagnosticCode
  • Modes: Reset, Disabled, Normal Operation
  • Logic: Comparison of actual vs. setpoint with conditional contact release
Possible applications
  • Speed monitoring of motors, conveyor belts or rotating axes
  • Early detection of underspeed as an indication of blockage, idling or mechanical faults
  • Integration into control and safety systems for status feedback
  • Testing and validating logic via virtual inputs without direct influence on actuators

Note: A complete technical inspection and approval by qualified personnel is required before productive use.

compatibility
  • Can be used in PLC systems with SCL support (e.g. Siemens TIA Portal)
  • Modular integration into higher-level control, diagnostic and safety architectures
  • Safe basic state when deactivated
  • Virtual inputs enable preparatory tests without real sensors
