OPC Tunnelling

Manufacturer: Kepware Technologies

The OPC Tunneler uses Client/Server architecture to transfer data over an Intranet, Internet or WAN. It also creates a secure OPC Tunnel through firewalls and complements existing OPC DA applications.

The OPC Tunnel provides end-users, integrators and automation suppliers with a favourable solution for remote connectivity to OPC applications. In comparison to remote OPC Connectivity via DCOM, the OPC Tunneler boasts security, ease of use and maintainability. Furthermore, there is no need to expose applications to unauthorized or anonymous users since OPC UA does not require a VPN connection for security.
