Networking different systems from diverse manufacturers—all of which feature different interfaces, profiles, and communication mechanisms—is the challenge of Industry 4.0 and the Industrial Internet of Things (IIoT). This is where OPC UA comes in. It creates a uniform basis for continuous information exchange from the field to the cloud.
OPC UA, short for Open Platform Communication Unified Architecture, enables the platform-independent, interoperable, and cross-vendor collaboration of machines in production. It makes communication between machines and systems possible—both in closed networks and via internet. But OPC UA is more than just a communication protocol: The architecture also includes data models and interaction concepts. Scalability is another great advantage of the standard. Depending on the requirements profile and scope of the application, the focus can be either on performance or security, for example, authorization, encryption, certification, or authentication.
In this article, we will show you what applications are possible with the open data exchange standard.
