RTSI Signal Considerations
The 7340 motion controller allows you to use up to eight RTSI trigger lines
as sources for trigger inputs, or as destinations for breakpoint outputs and
encoder signals. The RTSI trigger lines also can serve as a generic digital
I/O port. The RTSI star trigger line can be used only for a trigger input.
Breakpoint outputs are output-only signals that generate an active-high
pulse of 200 ns duration, as shown in Figure 5-9.
Figure 5-9. Breakpoint across RTSI
Encoder and Index signals are output-only signals across RTSI that are
the digitally-filtered versions of the raw signals coming into the controller.
If you are using the RTSI bus for trigger inputs or generic digital I/O,
all signals are passed through unaltered.
