Creating a Typical FieldPoint Application

Use the I/O controls on the I/O and Classic I/O palettes to specify the instrument or device resource with which you want to communicate. Use the VIs on the FieldPoint palette to develop FieldPoint distributed I/O applications. Most FieldPoint applications require only the FP Read VI and the FP Write VI. The FP Read VI returns data from the FieldPoint I/O channel or group of channels the FieldPoint IO Point function represents. The FP Write VI sends data to the FieldPoint I/O channel or group of channels the FieldPoint IO Point function represents. You also can use properties to extend the functionality of FieldPoint VIs programmatically.

Channels versus Items

FieldPoint modules consist of physical I/O points called channels. Items represent the channels or groups of channels. You can create items in Measurement & Automation Explorer (MAX) and use the FieldPoint I/O Point control to access the items in LabVIEW.

Using the FieldPoint I/O Point Control

Use the FieldPoint I/O Point control to communicate with the FieldPoint items you create in MAX. Place the FieldPoint I/O Point control in the front panel window. Right-click the control and select the items you want to read from or write to from the shortcut menu. If you do not see the FieldPoint items you want, configure the items in MAX.
