NI-Motion User Manual
You can create subroutines to run as onboard programs and execute them
from within an onboard program.
Figure 14-19 shows an onboard program algorithm that checks the I/O line
state to determine which onboard subroutine to execute.
Start program 2
Figure 14-19. Onboard Subroutine Algorithm
If the I/O line is active, the main onboard program calls an onboard
subroutine that rotates the motor clockwise. If the I/O line is inactive, the
main onboard program calls an onboard subroutine that rotates the motor
to counter clockwise.
