Communication Protocol OPC UA

Product catalog summary

Introduction to OPC UA
OPC UA (Open Platform Communication Unified Architecture) is an industrial standard developed by the OPC Foundation and released as IEC standard 62541. It is distinct from other OPC specifications due to its ability to not only transport data but also describe machine-readable data meaningfully.

Key Features of OPC UA

Service-oriented approach with internet capability.
Consistent data model for process, alarm, and historical data.
Platform independence and scalability to small systems.
Support for complex data structures with machine-readable descriptions.
Security implementation based on the latest standards.

OPC UA Communication Model
The OPC UA Communication Model defines the transport, coding, and security mechanisms through OPC UA Protocol Bindings. It controls access to information provided by the OPC UA server and offers a robust approach for modeling information.

Information Modeling
OPC UA allows the creation of advanced information models for specific user cases, similar to object-oriented programming. It supports the creation of complex data types and hierarchical structures, which can be predefined as device-specific, vendor-specific, or application-specific. These are specified within the "OPC Companion Specification."

Benefits for Clients
OPC UA clients, such as SCADA systems, can automatically identify type descriptions from connected information knots, facilitating the display and linking of information without programming effort.

Exchange of Information between Machines Industrial Standard OPC UA Compared with all other OPC specifications, OPC UA differs remarkably due to its capability to not just transport data, but also to describe machine-readable data in a meaningful way. OPC UA ( Unified Architecture) is an industrial standard issued by the OPC Foundation and is released as IEC standard 62541. Individual Specications of the Manufacturer Specializations for information models of other organizations OPC Information Model (data access, alarms, events …) Basic services Special implementation Modeling rules (Transport,...

Coming from basic rules for allocation of information (OPC Meta Model) and basic methods for data exchange (Build-In Information Models) it is possible to create any advanced information model for a dedicated special user case. Such pre-defined data types can be specified within “OPC Companion Specification”. Similar to object-oriented programming languages, additional data types can be created from existing data. More complex data types, like object files can be modeled with variables, methods and events. These kinds of data can be used to build further types with a hierarchical structure. The...
