OPC Tunnel

Softing’s OPC Tunnel enables a safe and secure method of network-spanning OPC communication while eliminating the problems associated with the configuration of DCOM security settings. This saves time and minimizes time-consuming calls to the vendor’s support staff.

OPC Tunnel removes the burden of figuring out how to network OPC clients and servers running on different platforms, in different network domains, and even in completely separated networks. Data exchange is fast, robust and reliable.

Fast start-up with Softing OPC Tunnel

OPC Tunnel is part of Softing’s OPC Easy Connect Suite. Used as a DCOM bypass, OPC Tunnel enables high-performance and robust communication between OPC components on networked computers. OPC Tunnel components are installed on both the OPC client computer and the OPC server computer.

Communication between the client-side and server-side OPC Tunnel components is via a TCP/IP connection (encrypted, if desired). The data between client and server applications is thus tunneled via TCP/IP, bypassing DCOM completely while eliminating time-consuming and nerve-wracking DCOM setup work.
