The default execution target is the development computer, or host computer. RT targets. Open a blank VI and display the block diagram.

Place a While Loop on the block diagram. Refer to the LabVIEW User Manual for information about using While Loops. Right-click the conditional terminal and select Create Control from the shortcut menu to create and wire a Stop button control to the conditional terminal. (FieldPoint) the FP Write VI. Create a control for the task/channel in input of the DAQmx Write VI and select an NI-DAQmx task.

Refer to step 3 for information about creating an NI-DAQmx task using the DAQ Assistant. (FieldPoint) Create a control for the FieldPoint IO Point In input of the FP Write VI. NI-DAQmx Control Loop The block diagram for a FieldPoint I/O system should look similar to Figure 3. FieldPoint Control Loop © National Instruments Corporation Getting Started with the LabVIEW Real-Time Module. The VI reads analog data and sends the data to the PID VI.

The PID VI processes the data using a PID control algorithm. The VI returns the results to the device.

Refer to the LabVIEW PID Control Toolset User Manual for information about using PID VIs. VI on the RT target can receive data from the First PID Control VI using Real-Time FIFOs and then use network communication methods to update the host computer VI. Refer to the LabVIEW Real-Time Module User Manual for information about using the Real-Time FIFO VIs. Right-click the While Loop and select Add Shift Register from the shortcut menu. Use While Loop shift registers to pass data from one iteration to the next. Refer to the LabVIEW User Manual for information about using shift registers.

Wire the rt fifo output of the RTFIFOCreate VI to the left terminal of the shift register and then wire the terminal to the rt fifo input of RTFIFORead VI. Notice that the thumbtack for RT Engine - Normal Priority Loop (TCP Comm) VI is in the horizontal position, shown at left, indicating that you have not downloaded the VI to the RT target. © National Instruments Corporation Getting Started with the LabVIEW Real-Time Module. VI to the RT target. Click the Run button. LabVIEW runs the VI on the RT target.

Select File»Exit without closing RT Engine VIs to close LabVIEW on the host computer while continuing to run the VIs on the RT target. Refer to the NI-DAQmx Help for information about timing control loops using the DAQmx - Data Acquisition VIs. Refer to the LabVIEW Real-Time Module User Manual for information about optimizing VIs for deterministic performance.
