Watch Our Software in Action

Connecting OPC Classic clients and servers across a network usually means fighting DCOM: complex permissions, blocked firewall ports and security gaps. OPCNet Broker (ONB) removes that problem. It’s an OPC tunneler that creates a secure OPC tunnel between OPC clients and servers over a single configurable TCP port, so you never have to configure DCOM.

In this demo, you’ll see OPC tunneling in action from start to finish:

1. Configuring the ONB Server and adding a connection in the ONB Client Configuration Tool
2. Connecting to remote OPC DA, OPC HDA and OPC A&E servers through the tunnel
3. Reading live and historical data with OPC Easy Archiver
4. Enabling encryption (server-side or client-side authentication mode)
5. Restricting access with Windows user accounts and ONB passwords

Why choose OPCNet Broker as your OPC tunneller?

1. No DCOM: connect OPC clients and servers without DCOM configuration
2. Secure by design: encrypted data transfer and user authentication
3. Firewall-friendly: OPC tunnelling over one TCP port
4. Complete OPC Classic coverage: supports OPC DA, HDA and A&E
5. Easy to deploy: set up in minutes with a simple configuration tool

Whether you’re replacing DCOM across sites or need a reliable OPC tunnel through firewalls and DMZs, OPCNet Broker gives you secure, high-performance OPC communication.
