Open Platform Communications United Architecture
OPC UA or OLE (Object Linking and Embedding) for Process Control Unified Architecture is an open source standard for communication in industrial automation. The purpose of OPC UA is to connect higher-layer software systems with lower layers.
Higher-layer systems include HMI screens, SCADA or MES and ERP systems, while lower-layer systems are PLC and DCS. It is based on the TPC/IP protocol and combines OLE and DCOM technologies.
Compatibility and scalability
The OPC UA is a platform-independent architecture that was created due to the need for compatibility and scalability in various projects and applications. OPC UA, unlike OPC, is not based on Microsoft’s OLE and DCOM technology and is thus extensible to other platforms such as OS X, Linux (JAVA) and Android.
OPC UA is a secure and reliable standard that specifies communications between devices (M2M) and between the machines and the IT and OT system. It is based on the concept of client-server, where the server is an application that provides its data to other applications, and the client is an application that requires or obtains data. In practice, developers strive to make applications that are clients and servers at the same time.
Independent architecture OPC UA
OLE for Process Control Unified Architecture provides a Service Oriented Architecture (SOA) that is based on different logical levels.
All of the basic services are abstract method descriptions which are protocol independent.
They provide the basis for Unified Architecture (UA) functionality in the OPC standard.
The basic components of UA functionality are the transport mechanism and the architecture of the standard.
