You can use an
Invoke Node in LabVIEW to start the User Program on your C Series Functional Safety module. You must start the User Program from LabVIEW
in the following situations:
You disable auto start in the User Program by deselecting the box on the
Module and Diagram tab of the Functional Safety Editor.
User-configurable faults in the User Program trigger Fail-safe Mode.
What to Do
Drag the C Series Functional Safety module (NI 935x) from the LabVIEW project and drop it onto the block diagram to create
a reference constant.
Right-click the reference constant and select
to place the Invoke Node.
Wire the reference constant to the reference terminal on the Invoke Node.
