Description

The FB_TempRelais function block monitors a temperature and registers any exceedance via a latched state ( #latched ), thus maintaining a one-time alarm condition. In simulation mode, the evaluation occurs immediately without latching. The output is via normally closed ( #NO_13_14 ) and normally open ( #NC_21_22 ) contacts, which are only active when the optional inputs ( #Input_13 , #Input_21 ) are set.

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 undesired switching states.

How it works
Reset

With #Reset the self-holding ( #latched ) is deleted, so that the block returns to the normal state.

Disabled

If #Enable is not active, all outputs remain inactive, the block reports no error and shows a neutral state.

simulation

In simulation mode, the temperature is evaluated directly against the threshold ( #HI_Limit ). If the value exceeds the limit, #latched is set without the need for permanent self-holding—the outputs reflect the state accordingly.

Normal operation

In real-time operation, a temperature overshoot ( #Temp ≥ #HI_Limit ) sets the latch ( #latched ) once, which remains until a reset occurs. The contacts only transmit the state if the corresponding enable inputs are active:

  • #NO_13_14 (normally closed) is active if there is no latch and #Input_13 is set.
  • #NC_21_22 (normally open) is active when Latch is set and #Input_21 is set.
Technical details
  • Inputs: #Enable , #Reset , #SimMode , #Temp , #HI_Limit , #Input_13 , #Input_21
  • Internal state: #latched – self-holding when exceeded
  • Outputs: #NO_13_14 (normally closed), #NC_21_22 (normally closed)
  • Status & Diagnosis: #Error , #Status , #DiagnosticCode
  • Modes: Reset, Disabled, Simulation, Real Operation with Latching
  • Logic: One-time triggering in case of overtemperature, hold via latch until reset
Possible applications
  • Monitoring of temperature limits with clearly visible status display
  • Persistent alarm (latch) after a single exceedance
  • Testing and validation in simulation mode without real temperature change
  • Linking to higher-level control and alarm chains via release inputs

Note: Before use in productive operation, a complete test and approval by qualified personnel is required.
