The window modes allow firing to occur, or be enabled, based upon axes being within a
user-defined window. The +/- and Enter/Exit Detection block within the block diagram is
used to prevent false triggering due to one bit dither on an axis, etc. Window modes may
not be pre-scaled as indicated in the block diagram.
Data Capture mode allows the encoder position to be captured at the PSO trigger
locations. Data Update mode allows analog or digital outputs to be set by the same
trigger. The capture and update modes are defined in Figure 3-12. For a full description
of these modes, refer to the Soloist HMI help.
