In addition to the OPC UA Client driver and the OPC UA server interface, KEPServerEX also provides OPC DA, OPC AE, DDE, and several vendor-specific interfaces. Kepware's OPC Tunneling solution can be used with a range of products, including third-party OPC clients and OPC servers. KEPServerEX: A Single Server and Tunneling Solution Kepware's OPC Tunneling solution is an ideal way to share information in real-time with B2B applications for automation. Furthermore, there is no need to expose applications to unauthorized or anonymous users since OPC UA does not require a VPN connection for security. In comparison to remote OPC connectivity via DCOM, the OPC Tunneler boasts security, ease of use, and maintainability. The OPC Tunnel provides end-users, integrators, and automation suppliers with a favorable solution for remote connectivity to OPC applications. It also creates a secure OPC Tunnel through firewalls and complements existing OPC DA applications. The OPC Tunneler uses client/server architecture to transfer data over an Intranet, Internet, or WAN. This eliminates reliance on Microsoft COM and DCOM technology, and provides secure, authenticated communications and higher performance.
The OPC UA Client driver provides a communications protocol between two or more computers, allowing data to be transferred securely and reliably. The OPC UA Client driver paired with the OPC UA Server interface of another KEPServerEX implementation provide an ideal secure tunneling solution.
