Description
This SCL function block, FB_IncubationSystemControl, monitors and controls temperature, humidity, and automatic egg turning in an incubator. It pauses when the door is open, offers manual and automatic operation, and provides information via alarm and status texts. It runs 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

  1. Door open → Heater, humidifier & motor reversing off, alarm on, HMI "Door open - process paused", RETURN
  2. Manual mode → all controls off, HMI “Automatic OFF”, RETURN
  3. Automatic mode →
    • Temperature control ±0.5 °C: Actual < target tolerance → heating on; Actual > target + tolerance → heating off
    • Humidity control ±3%: analog with humidifier
  1. Turning cycle every 2 hours (TON timer): Motor turn on until limit switch edge → Motor turn off, TurnActive=false, Cycle counter++
  2. No turn active → HMI “Automatic active”

Technical details
• Inputs: DoorOpen, Automatic, TempActual, TempSetpoint, HumidityActual, HumiditySetpoint, Limit Switch, Acknowledge
