Description
The FB_Climate Monitoring function block monitors temperature and humidity, scales analog raw values, controls fans and humidifiers when limit values are exceeded, and summarizes alarms in a single variable. Implemented in SCL, it can be used directly in the Siemens TIA Portal.

Note: All modules are designed exclusively as a learning and optimization basis and are not approved for live operation. System modules, in particular, must be finally tested and commissioned by qualified personnel before productive use.

How it works

  • Stop ( Stop=TRUE ):
    → all alarms & actuators off, StatusText=“System gestoppt” , RETURN
  • Scaling :
    → Temperature = Temp_RAW × 50 / 27648
    → Humidity = Humidity_RAW × 100 / 27648
  • Temperature monitoring ( Start=TRUE ):
    – Temperature > TempMax → AlarmTemp=TRUE , Fan=TRUE, StatusText=“Temperatur zu hoch”
    – otherwise → both off
  • Humidity monitoring ( Start=TRUE ):
    – Humidity < HumidityMin → AlarmFeuchte=TRUE , Humidifier=TRUE, StatusText=“Feuchte zu niedrig”
    – otherwise → both off
  • General alarm :
    – AlarmGesamt = AlarmTemp OR AlarmFeuchte
  • Acknowledgement ( Quittieren=TRUE ):
    → all alarm flags reset, StatusText=“Alarm quittiert”

Technical details

  • Inputs: Stop, Start, Temp_RAW (INT), Humidity_RAW (INT), TempMax (REAL), HumidityMin (REAL), Acknowledge
  • Outputs: AlarmTemp, AlarmHumidity, AlarmTotal, Fan, Humidifier (each BOOL), StatusText (STRING)
  • Scaling: simple proportion calculation in REAL
  • Logic: IF/ELSIF with RETURN on stop, no timers

Air conditioning and ventilation systems in offices, laboratories, machine rooms, greenhouses, and agricultural equipment; PLC training projects.
