Automated Cutting Machine HMI System (CC05 SmartLink) The Challenge: The client required a modern Human-Machine Interface (HMI) to automate the workflow of their CC05 Cutting Machine. The system needed to bridge the gap between operator barcode scanning, centralized production databases, machine PLCs, and label printers in a seamless manner. Key Difficulties: Establishing direct communication with Mitsubishi FX5U PLCs over a TCP/IP LAN without relying on expensive third-party OPC servers. Automating the label printing process by sending raw commands directly to Zebra printers without using standard Windows print drivers, ensuring zero delay. Providing robust offline capabilities for operation history logging and instant label reprinting in case of hardware or network issues. Solution Architecture WP Solution developed CC05 SmartLink, an industrial-grade C# .NET 8 WPF application acting as a comprehensive middleware HMI. The workflow is entirely barcode-driven; operators simply scan a Control Number or Order Number to automatically retrieve production parameters (such as Cut Length, Project No, and Model) from a central SQL Server. Once the machine is commanded to start, the system communicates directly with the PLC, listens for the “Machine Complete” signal, and dynamically generates and prints Zebra ZPL labels. ...

Knuckle Production Data Link System The Challenge: An “Automotive Tier 1 Manufacturer” required an automated digitalization system to record Scan-In/Scan-Out times for Knuckle parts during the CNC process. All data needed to be stored in a central database for full traceability. Key Challenges: Legacy System Integration: The existing production line utilized Mitsubishi Q-Series (Q03/Q06) PLCs, which were difficult and costly to modify. Data Logic: Clearly separating Left-side and Right-side production data, then synchronizing them at the final Visual Inspection stage. Efficiency: Data transmission must be seamless without affecting the machine’s cycle time. Solution Our team implemented a “Direct Integration via SDK” strategy. We developed a custom C# (.NET) Application to communicate directly with three Keyence SR-2000 scanners using Socket (TCP/IP) protocols. This “Non-Invasive” approach allowed us to extract production data without interfering with the client’s original PLC logic. ...
