Using the OPC UA Protocol with ixArma
Using the OPC UA Protocol with ixArma
OPC UA (Open Platform Communications Unified Architecture) is a secure, platform-independent communication protocol designed for industrial automation and the Industrial Internet of Things (IIoT). It enables seamless, standardized data exchange between devices, machines, and systems from different manufacturers and operating systems.
Why use OPC UA?ixArma 7.3 supports the full functionality of OPC UA, and our edge devices, ixArmaBox and ixArmabox+, enable cloud and portal customers to use this communication protocol.
- Cross-platform and interoperable: Unlike its predecessor, OPC Classic, OPC UA is not tied to Windows. It runs on Windows, Linux, macOS, embedded systems, and even IoT devices, enabling integration into various hardware and software environments.
- Enhanced security: OPC UA offers robust security features, including authentication via X.509 certificates, data encryption, integrity checks, and role-based access control, making it ideal for secure communication across firewalls and the Internet.
- Scalable and future-proof: It supports both client/server and publish/subscribe (PubSub) communication models, enabling flexible architectures ranging from local control systems to cloud-based IIoT applications.
- Standardized data modeling: OPC UA uses an information model to represent real-world assets (such as machines, sensors, or processes) as objects with properties, methods, and events. This enables comprehensive, context-aware data exchange that goes beyond simple values.
- Industry 4.0 and Digital Transformation: OPC UA is the recommended communication standard in the RAMI 4.0 reference architecture model for Industry 4.0. It is essential for achieving vertical and horizontal integration between manufacturing systems (PLCs, HMIs) and enterprise systems (MES, ERP, cloud platforms).
- Another advantage of the OPC UA protocol is its vendor independence: No matter which manufacturer supplied your hardware—thanks to the standardized protocol, all devices can communicate with one another. The OPC UA protocol is now frequently used for automation in the manufacturing sector, in warehousing, and in advanced building management. Both our ixArma software for the cloud and the edge devices we use (ixArmaBox and ixArmaBox+) are designed for this purpose. The same applies, of course, to on-site installations of ixArma.
