OPC UA

As industrial systems continue evolving toward greater interconnectivity, the need for standardized, secure, and interoperable communication protocols becomes critical. OPC Unified Architecture (OPC UA) addresses this need by providing a platform-independent framework for seamless data exchange between machines, control systems, sensors, and enterprise software. Designed for secure, reliable, and extensible industrial automation, OPC UA supports a wide range of architectures—from on-premise control systems to cloud-based analytics platforms. Its flexibility makes it suitable for factory automation, smart manufacturing, utilities, and energy systems. MeshNetworkPro delivers scalable OPC UA solutions tailored to the needs of industrial B2B organizations across North America. We support implementation through robust system design, expert technical assistance, and advanced integration services. Our goal is to help clients achieve interoperability, data transparency, and predictive insights with long-term reliability and minimal vendor lock-in.

Case Studies

United States Case Study 1 – Smart Energy Grid Monitoring

A midwestern U.S. utility provider integrated OPC UA-enabled devices into its substations and transformer control units. MeshNetworkPro provided the architecture and GAO Tek Inc.’s rugged DAQ hardware for high-frequency sampling and secure data transport to SCADA. The result was faster fault detection, reduced maintenance costs, and remote monitoring capabilities

United States Case Study 2 – Food Production Line Modernization

A major U.S. food processor in New York upgraded their legacy PLC network using OPC UA-enabled controllers. MeshNetworkPro integrated an edge compute gateway that published machine data to their MES and cloud analytics system. Production visibility improved by 63%, and unplanned downtimes reduced by 41%.

Canadian Case Study – Pharmaceutical Compliance Automation

A pharmaceutical company in Ontario implemented OPC UA for process control and audit trail visibility in line with CSA and IEC standards. MeshNetworkPro deployed OPC UA stacks and validated integration with lab equipment and ERP. Result: improved regulatory compliance and digital batch reporting.
