Integrating OPC Data with Linux and QNX Systems

OPC server in Windows to Oracle in Linux

An IT manager in a municipality office has created a live data link between a Lookout OPC server in Windows and a custom Linux application. He has an OPC DataHub connected to his OPC server, mirroring data to a Cascade DataHub running in Linux. On the Linux side, he feeds the data into an Oracle database, and from there into his custom application. The data updates are so seamless that his Linux application thinks it is directly connected to the Lookout OPC server.

Linux server connected to Windows OPC server to access proprietary PLC network

A chemicals producer in the United States is using the OPC DataHub and Cascade DataHub to access data from a proprietary PLC network. The PLCs are connected to a Linux computer running the Cascade DataHub. The Cascade DataHub is connected to an OPC DataHub running in Windows. This architecture gives them access to the PLC data using standard OPC client software in Windows.

OPC server in Windows connected to client on QNX 6 computer

A company in the US is using the OPC DataHub to connect a custom control application running QNX 6 to an OPC server running on a Windows network computer. The OPC DataHub is used to connect to the server in Windows. The OPC DataHub mirrors data with the Cascade DataHub running on the QNX 6 computer. The Cogent API in QNX was used to connect between the control program and the Cascade DataHub.
