Automatic bottle capper

Description
This compact function block controls a motor with safety enable, monitors a light curtain for interruptions and provides a manual acknowledgement function.

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/Release ( NotHalt=TRUE ∨ FreigabeBetrieb=FALSE ):
  → Motor_EIN=FALSE , Warnleuchte=TRUE , Fehler_gemerkt=TRUE , Acknowledgement required
• Light curtain ( Lichtvorhang_UNTERBROCHEN=TRUE ):
  → Motor_EIN=FALSE , Warnleuchte=TRUE , Fehler_gemerkt=TRUE , Acknowledgement required
• Acknowledgement (edge Quittierung FALSE→TRUE ):
  → if Lichtvorhang_UNTERBROCHEN=FALSE , Fehler_gemerkt and Quittierung_aktiv are reset
• Operation :
  → if StartSignal=TRUE ∧ no Fehler_gemerkt , Motor_EIN=TRUE ; otherwise blocked

Technical details

• Highest priority: NotHalt , FreigabeBetrieb deactivate immediately Motor_EIN & warning light
• Edge detection: Internal flag Quittierung_alt for rising edge
• Inputs: StartSignal , NotHalt , FreigabeBetrieb , Lichtvorhang_UNTERBROCHEN , Quittierung
• Outputs: Motor_EIN , Warnleuchte , Fehler , Fehler_gemerkt , Quittierung_aktiv

Possible applications

• Safe motor control with light curtain function
• Conveyor belts, portal axes or rotating bodies in production lines
• Demonstration and training environments for PLC safety technology
