Solution
Because DAQmx timing configuration settings such as sample rate and sample clock are DAQmx task properties and not channel properties, a more traditional method has to be used to publish your acquired data to a shared variable. In LabVIEW, you can use a DAQmx example program that acquires analog strain data as a starting point and from there simply write your data received by the DAQmx Read VI to a network published shared variable. Once a Shared Variable has been created using the Network-Published scope, all data written to the variable is available to all systems networked with the host computer, including a OPC quick client.
