Advantages of OPC Unified Architecture
The OPC Unified Architecture is an operating System independent standard for communication of different client – server systems via different network type.
Safe and robust connection due to
- Signing
- Encryption
- User authentication
- Detection of transmission errors
- Resending of lost messages
Self-Description of the Server
- Transfer of the node structure
- Transmission of semantics
The specifications of security mechanisms in the protocol ensure secure, robust and authenticated message transmission between client and server systems. The specification of a new address space, which contains not only data but also its semantics and description, created a connection from the process level (controllers, plant level) up to management systems.
