The MatrikonOPC UA Proxy enables existing OPC Classic client applications to connect and communication with Unified Architecture (UA) servers and devices. This allows users to integrate emerging UA products into existing OPC Classic infrastructure.
The OPC UA Proxy provides the easiest all-around user experience when it comes to searching, selecting, and connecting to UA servers. Providing secure communication, it also eliminates DCOM, as the OPC UA Proxy is installed local to the OPC Client.
