Machine vision is a cornerstone of modern manufacturing quality control, ensuring product consistency and reliability. However, many facilities face a dilemma: while their existing vision systems remain mechanically sound, their analytical capabilities lag behind evolving manufacturing requirements. Vision Link offers a solution that brings AI-powered inspection to existing camera systems without requiring costly hardware replacement or extensive control system modifications.
The Challenge: Legacy Vision Systems Limit Quality Control Effectiveness
Manufacturers have invested heavily in vision inspection systems that reliably perform basic functions. With operational lifespans exceeding a decade, these systems represent significant capital investments. However, traditional systems face limitations in today’s manufacturing environment.
The core issue begins with the technology itself: fixed detection algorithms struggle with product variations and changing conditions, and pattern-matching approaches demand extensive programming for each new product variant. This technical limitation is compounded by the systems’ outputs: binary pass/fail results provide minimal insights for root cause analysis, leaving operators to manually classify defects, which consumes valuable time and introduces inconsistency.
The problems extend to broader data management and adaptability. Limited connectivity creates data silos that prevent meaningful statistical process control and trend analysis. This lack of data integration results in inadequate defect history, complicating regulatory compliance and audit processes.
Production engineers need enhanced detection capabilities, while control engineers hesitate to modify functioning logic. Quality teams lack useful data for process improvements, often resorting to manual record-keeping. Total system replacement addresses these issues but comes at a prohibitive cost—often millions per facility — along with downtime and revalidation challenges.
What is Vision Link?
Vision Link is an AI-powered inspection platform that is designed to work in tandem with installed camera infrastructure, closing the gap between legacy hardware and cutting-edge inspection technology. The platform integrates with vision systems that support FTP or SFTP output, maintaining all existing functionality and augmenting it with advanced inspection capabilities.
Universal compatibility allows integration with industry-leading vendors including Cognex, Keyence, Omron, Teledyne, Basler, and Allied Vision. It supports diverse imaging technologies — area scan, X-ray, line scan, thermal, hyperspectral, and microscope imaging. Processing speeds of less than 250 milliseconds ensure real-time inspection capabilities critical for production environments.
The system’s AI-powered inspection tools perform defect detection and classification, multi-class sorting, presence-absence verification, OCR reading, barcode scanning, and color analysis. Each edge vision controller accommodates up to eight cameras for complex manufacturing setups. Control system integration works through industry-standard protocols including Ethernet/IP, Modbus TCP, and Allen-Bradley PLC Tag Client.
Vision Link enables centralized monitoring and management of distributed inspection systems across multiple production lines or facilities. From an engineering perspective, it minimizes disruption to existing infrastructure and control logic — recognizing manufacturing environments where production continuity is paramount and risk mitigation is essential for new technology adoption.
How It Works
Vision Link employs a parallel processing architecture that preserves all existing functionality while adding new capabilities. The primary vision system continues operating unchanged, maintaining its established communication with PLCs and other control elements. Simultaneously, the same images are processed by Vision Link’s edge vision controller, which analyzes them using advanced AI models specifically trained for the application.
This approach offers several key advantages for manufacturing facilities. It requires no modifications to existing vision hardware or settings, preserving validated inspection parameters. Established PLC programs and HMI interfaces remain unchanged, eliminating costly revalidation requirements. The system operates with standard industrial networking capabilities without specialized IT infrastructure. Additionally, inspection processes continue uninterrupted during temporary internet outages, maintaining production continuity.
The system implements a hybrid cloud-edge approach tailored for manufacturing environments with stringent security and reliability requirements. AI models are trained in a secure cloud (SOC 2 Type II certified, Zero Trust Architecture), then deployed to the edge vision controller for local processing with minimal latency. This allows uninterrupted production even during network outages.
Engineering Interface and Workflow
Vision Link features a web-based interface accessible from an HMI on the factory floor or remotely via standard web browsers, eliminating the need for specialized software installation or dedicated workstations. It provides tailored capabilities for different teams.
Production engineers benefit from comprehensive defect classification and trend analytics across multiple dimensions. Quality metrics dashboards feature historical data and statistical process control, while advanced filtering enables faster root cause analysis and reduced downtime. Through remote access, engineers can review full inspection records for quality investigations and audits. Built-in image annotation tools support continuous model training and improvement. The platform also includes customizable reporting tools to streamline quality reviews and compliance documentation.
Control engineers can implement PLC integration via standard protocols without custom programming requirements. The system includes comprehensive status monitoring and diagnostics with automated alerts, while simultaneously enabling remote edge device management and maintenance. From a security perspective, the platform incorporates role-based access control aligned with facility standards. To support compliance efforts, complete audit logging tracks all system changes and configuration management, ensuring operational transparency.
With Vision Link, quality teams gain access to comprehensive defect databases for statistical trend analysis, regulatory compliance, and customer audits. Teams can create customizable quality reports with automated generation and distribution. Additionally, the system enables comparative analysis across production batches, shifts, and material batches, revealing patterns that might otherwise remain hidden.
Case Study: A Global Leader in Sustainable Packaging Solutions
A global leader in sustainable packaging solutions installed Vision Link at a facility with an established line scan inspection system monitoring critical surface quality parameters. Their existing system was reliable but limited, requiring extensive manual intervention for defect validation and classification—over 375,000 manual classifications annually, consuming approximately 1,000 labor hours.
Implementation took just one week, without disrupting ongoing operations. The team installed and configured the edge vision controller on the network, then established an SFTP connection to the existing vision system’s image output. They integrated with Allen-Bradley ControlLogix PLC using standard EtherNet/IP protocols. Engineers trained the AI models using historical images across multiple product categories, with final validation against manually classified reference sets to verify accuracy.
The facility eliminated virtually all manual classification while maintaining production speed. More importantly, they achieved significant reductions in false positives and material waste. The cloud-based analytics enabled the quality team to identify recurring patterns and address upstream manufacturing issues that had previously gone undetected. The facility achieved quantifiable ROI through reduced labor costs and decreased material waste, with complete payback realized within the first six months of operation.
Implementation Process
Vision Link’s implementation process is designed to minimize disruption and resource requirements for both production and controls teams, with clear milestones and responsibilities:
- Hardware installation: Connect the edge vision controller to the existing network infrastructure
- Vision system integration: Configure FTP/SFTP for automated image transfer
