10.8.2 Controlled Sequence Advance Mode
When the controlled sequence advance mode is selected the advance from one sequence set to
the next proceeds in ascending sequence set index numbers according to the selected sequence
control source:
Always Active: The advance from one sequence set to the next proceeds automatically as
frame triggers are received.
Line 1: The states of the input line 1 control sequence set advance.
Disabled: Sequence set advance is only controlled by AsyncAdvance software commands.
The Sequence Set Total Number parameter specifies the total number of different sequence sets
that are available and included within a sequence set cycle. The maximum number is 64.
10.8.2.1 Operation with the "Always Active" Sequence Control Source
Operating the Sequencer
When the Always Active sequence control source is selected the advance from one sequence set
to the next proceeds automatically in ascending sequence set index numbers as frame start triggers
are received.
The following use case (see also Figure 98) illustrates the operation of the sequencer in
controlled sequence advance mode with Always Active selected as the sequence control source.
As images are captured continuously, the camera advances automatically with no action by the user
from one sequence set to the next in ascending sequence set index numbers. After one sequence
set cycle is complete, another one starts.
In this use case, the Sequence Set Total Number parameter was set to six. Accordingly, the
available sequence set index numbers range from 0 through 5. The frame start trigger is set for
rising edge triggering.
Assuming that the camera is in the process of continuously capturing images, the sequencer
feature operates as follows:
When the sequencer feature becomes enabled, the sequence set cycle starts: The parameter
values of the sequence set with sequence set index number 0 are loaded into the active set
modifying the active set.
This way of operating the sequencer feature is similar to operating it in auto
sequence advance mode when each sequence set is used only once per
sequence set cycle.
Here, however, the first sequence set used for image acquisition after the
sequencer feature was enabled is sequence set 1 as opposed to sequence set 0
in auto sequence advance mode.
