Going Beyond Performance Limitations of OPC DA Implementation
Y. Veryha · 2006
One of the most important factors in building high-performance, scalable industrial control applications is the ability to transfer process data from the server to the client machine in the most efficient and fast way. OPC DA is widely accepted and used as the standard in automation and network control systems. We present a system and method for caching process data in large industrial control systems to overcome performance limitations of the OPC DA implementation. Our approach for large network control systems includes a powerful and easy-to-use client data cache that allows overcoming typical performance limitations of the OPC DA implementation for large data transfers
