Use the following guidelines to develop an application with the LabVIEW Datalogging and Supervisory Control (DSC) Module.

1. Plan the application requirements, including requirements for channel count, hardware or other I/O sources, data logging, security, and performance.

   Note  Do not skip step 1. This step impacts decisions at every stage of development, including setting up servers, configuring shared variables, and setting up network clients and servers.

2. Physically establish a connection to the hardware. Connect, configure, test, and troubleshoot the hardware.
3. Configure I/O servers to communicate with the hardware. Use the NI Shared Variable Monitor, available by selecting Tools»DSC Module»Monitor Variables, to verify that you successfully established a connection to the hardware.
4. Use the Batch Variable Creation dialog box, available by right-clicking a library in the Project Explorer window and selecting Create Variables from the shortcut menu, to create many shared variables in one batch. You also can use the Create Bound Variables dialog box, available by right-clicking a library in the Project Explorer window and selecting Create Bound Variables from the shortcut menu, to bind the shared variables you create to I/O server data items. Repeat step 3 to verify that the shared variables communicate with the I/O source.
5. Add additional shared variables and configure data logging and alarming as necessary for your application.
6. Build the Human Machine Interface (HMI) portion of the application.
7. Use the LabVIEW and DSC Module VIs and functions to add additional functionality to the HMI application.
8. Test, deploy, and document the application. Use the NI Shared Variable Monitor to troubleshoot the application if you find problems while testing.
