Case Study: HollySys achieves high-performance, scalable OPC UA connectivity with Honeywell (Matrikon FLEX)

Hollysys turns to matrikon for native OPC UA Connectivity

HollySys, a global provider of process, factory and rail automation systems, needed reliable, embedded OPC UA connectivity for its MC-series motion and PLC controllers so they could integrate with a wide range of third‑party systems. After four years of unsatisfactory in‑house development, HollySys selected Honeywell’s Matrikon FLEX OPC UA SDK to meet requirements for high performance, scalability in embedded environments, and strong local technical support.

Honeywell’s Matrikon FLEX was embedded across HollySys product lines—from MCU‑based devices to multicore servers—providing a simple API that reduced OPC UA development effort, optimized CPU and memory use, and supported OPC UA security (encryption and authorization). The result: HollySys now uses a single SDK across products, achieved higher throughput and uptime with lower resource consumption, accelerated time‑to‑market, and gained ongoing local support from Honeywell.
