Position Breakpoints Using RTSI
You can use the Select Signal function to route position breakpoints using
one of the RTSI lines. In this case, the motion controller triggers the
external device at a given position, as shown in Figure 12-22.

Encoder Pulses Using RTSI
You may need to trigger the external device to acquire data every encoder
phase or on an encoder index pulse, as shown in Figure 12-23.

Software Trigger Using RTSI
You can use the Set I/O Port MOMO function to write directly to the RTSI
lines to trigger other devices, as shown in Figure 12-24.
