OPC UA Bridge

OPC UA Bridge for secure and reliable OPC tunneling

Standardized and secure communication from the field device to the cloud is considered key for the implementation of Industry 4.0.
Integration Objects’ OPC UA Bridge helps you make a smooth transition to the IoT and Industry 4.0. It ensures seamless integration for OPC UA and OPC Classic architectures. More specifically, it ensures secure and reliable OPC Classic-to-OPC UA bridging and vice-versa.

Moreover, this OPC bridge tunnels through firewalls to connect classic OPC servers and clients. This eliminates DCOM bottlenecks and vulnerabilities, and enables networked OPC systems to access real-time data‚ historical data, alarms and events without the usual frustrations involved with DCOM configuration.
