This article describes the application of the S7–1500 series PLC and the Cognex barcode reader DM8700 in an automotive engine block production line. The PLC controller is connected via Profinet communication to the DM8700 barcode reader, which can read barcodes or QR code information. Use the Dataman Setup Tool software to set up the hardware of your Cognex barcode reader, including the IP address of the barcode reader, device name, scanning type, communication mode, and more. The controller and the barcode reader are hardware configured via the Siemens TIA Portal software and communicate via a PROFINET network. The barcode reader reading process is programmed to process the information taken by the barcode reader, output the data in string format, and proofread the obtained information to ensure the accuracy of the data.
