# Release Summary

The Wonderware OPCLink I/O Server is a Microsoft Windows application program that acts as a communications protocol converter. It allows other Windows application programs access to data from local or remote OPC servers. OPCLink detects automatically which OPC data access version is implemented in OPC servers, and uses the latest version available.

OPCLink connects to OPC servers, converts client commands to OPC protocol, and transfers data back to clients using DDE, FastDDE, or SuiteLink™.
