In NI-DAQmx 8.0 or later, you can set up distributed applications to combine remote data applications using the NI-DAQmx I/O Server. For instance, you can configure a central computer to monitor other computers that control hardware sensors by using shared variables. You can connect to the NI-DAQmx I/O Server through LabVIEW 8.0 or later, but LabVIEW is not required. If you use a third-party OPC client, you also can access DAQ channels.
When using a third-party OPC client, connect to the variable engine server to access DAQ channels on the network.
Refer to the LabVIEW Help for information about binding to a DAQ channel using a shared variable in a LabVIEW Project.
