Track&trace production data
|
- The higher-level system (MES=Manufacturing Execution System) creates a Data Matrix code. The 2D code is transmitted to a PLC.
- The PLC transmits the 2D code to the Laser Marker.
- The Laser Marker marks the product with the 2D code.
- The object is detected by a laser sensor.
- The 2D Code Reading Sensor, e.g. PD60, checks the product and code before the next production step.
- Production step.
- The 2D Code Reading Sensor checks the product and code after the production step, collects the machine parameters and stores them in the higher-level system.

Laser Markers
|
|
A unique, permanent marking is necessary in the first process step to ensure that product data is recorded perfectly and smoothly and to guarantee traceability during the fabrication of the solar panel. With the help of this state-of-the-art identification technology, the requirements of DIN EN 50380 can be met, e.g. a 25-year traceability. Moreover, this kind of identification protects against theft and forgery.
