Description

The FB_VoltageRelay function block monitors a voltage and evaluates whether it is within a defined range ( #LO_Limit < #Voltage < #HI_Limit ). The result is evaluated internally as #tempOK . The switching behavior can be specifically enabled via virtual inputs for normally closed and normally open contacts ( #Input_13 , #Input_21 ). If the voltage is within the valid range, the normally closed contact is activated; if it is outside the valid range, the normally open contact is activated.

Note: This logic is intended as a template. Before productive use, it must be integrated, tested, and approved by qualified personnel. Improper use may result in incorrect switching states.

How it works
Reset

With #Reset the output is reset to the safe initial state: The normally closed contact signals "Voltage OK," the normally closed contact is deactivated. Status shows Reset.

Disabled

If #Enable is not set, both contacts are disabled. The block behaves passively without reporting errors.

Active

The measured voltage is checked. If it lies between the limits ( #LO_Limit and #HI_Limit ), it is considered valid ( #tempOK = TRUE):

  • #NO_13_14 (normally closed) is only set if #Input_13 is active and #tempOK is TRUE.
  • #NC_21_22 (normally open) is only set if #Input_21 is active and #tempOK is FALSE (inverted).

The status is set to OK, errors are reset.

Technical details
  • Inputs: #Enable , #Reset , #Voltage , #LO_Limit , #HI_Limit , #Input_13 , #Input_21
  • Internal state: #tempOK – TRUE if voltage is within the permissible range
  • Outputs: #NO_13_14 (normally closed), #NC_21_22 (normally closed)
  • Status & Diagnosis: #Error , #Status , #DiagnosticCode
  • Modes: Reset, Disabled, Normal Operation
  • Logic: Area monitoring with conditional output via enabled virtual contacts
Possible applications
  • Voltage monitoring with clear switching output when exceeding or falling below the voltage
  • Simulation of contact releases without physical hardware for validation
  • Integration into control and diagnostic chains to display valid voltage states
  • Ensuring defined operating conditions through threshold logic

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 control, safety and diagnostic architectures
  • Deactivated state without unwanted switching operations
  • Virtual inputs allow preparatory tests without real hardware
