PLC-controlled labeling machines represent the standard for modern, flexible labeling automation, where a programmable logic controller (PLC) manages all machine functions with high reliability and precision. The PLC integrates servo motors, sensors, and pneumatic actuators to execute complex labeling patterns, adjust parameters in real-time, and store recipes for quick changeover between products. Operators interact through a touchscreen HMI, setting label position, speed, and tension without mechanical adjustments. For example, a contract packager might use a PLC-controlled labeler to handle hundreds of different container types daily, with each recipe recalling the exact settings for label placement, conveyor speed, and verification parameters. The PLC also enables advanced functionalities such as predictive maintenance alerts, production counting, and OEE tracking. Communication capabilities (Ethernet/IP, Profinet) allow integration into factory SCADA systems for centralized monitoring. In pharmaceutical applications, the PLC ensures data integrity with audit trails and user access controls. These machines are built for long-term stability and reduced maintenance through solid-state control.
