Pharmaceutical tablet filling
Couldn't load pickup availability
Description
The FB_Abfuellung_Tabletten function module controls tablet filling with packaging recognition. The code is implemented in SCL and can be used directly in the 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
-
Emergency Stop (
NotAus=TRUE):
→Zufuehrung=FALSE,VentilFreigabe=FALSE,Alarm=TRUE,StatusText=“NOT-AUS aktiv!”,RETURN -
Packaging missing (
SensorVerpackung=FALSE):
→Zufuehrung=FALSE,VentilFreigabe=FALSE,SignalVerpackung=TRUE,StatusText=“Verpackung fehlt!”,RETURN -
Filling (
Start=TRUE∧SensorVerpackung=TRUE):
→Zufuehrung=TRUE,VentilFreigabe=TRUE,StatusText=“Abfüllung läuft”;
Edge detection onSensorTablettecounts toZielmenge, incrementsIstmenge.
IfIstmenge≥Zielmenge→Zufuehrung=FALSE,VentilFreigabe=FALSE,StatusText=“Zielmenge erreicht”. -
Reset (
ResetZaehler=TRUE):
→Istmenge=0,StatusText=“Zyklus zurückgesetzt”

Outputs:
Zufuehrung,VentilFreigabe,SignalVerpackung,Alarm,StatusText,Istmenge -
Logic:
-
RETURNin case of emergency stop or missing packaging - Edge detection for precise counting
- IF structure for process flow and reset
