Managing Shared Variables with the Channel View

The Channel View is a central location for viewing and configuring hardware and shared variables. You can use the Channel View to view and read the values of shared variables on the local machine or local network.

The Channel View displays hardware devices by default. Select Shared Variables from the View pull-down menu at the top of the Channel View to display all the shared variables that exist on the local machine or local network. In the Shared Variable Name column, expand Localhost to display shared variables that are available on the local machine. Expand Network Neighborhood to display machines on the local network. You also can click the Add Machine button and enter a machine name or IP address to add a machine to the Channel View.

Networks, machines, and shared variables appear with checkboxes in an Acquire column. Use the Acquire checkbox to specify whether to read the values of shared variables. When you place a checkmark in the Acquire checkbox, a Sample Period (s) column appears, and LabVIEW SignalExpress automatically places a Read Shared Variables step in the Project View. LabVIEW SignalExpress configures the step to match the options you specify in the Channel View.

Note  You also can use the Properties window to quickly configure multiple shared variables.

Place a checkmark in the Acquire checkbox for a machine to read the values of all the available shared variables on that machine. If you select multiple shared variables, LabVIEW SignalExpress uses one Read Shared Variables step to read the values of any shared variables that have the same sample period.
