Use Case Two in Detail
Assuming that the sequencer sets are configured according to Table 51 on page 236 and the
camera is not acquiring images, the sequencer feature operates as follows:
When the Sequencer Mode parameter value is set to On the sequencer feature becomes
enabled for the application of sequencer sets during image acquisitions. The transitional
"dummy" sequencer set with index number -1 is loaded into the active set, overwriting the
previous sequencer parameter values (Section 7.7.2 on page 217).
When a frame start trigger signal is received, sequencer set 0 is automatically loaded into the
active set and is used for the image acquisition. The image data are processed and
transmitted out of the camera.
The current frame start trigger count of Counter 2 is found to be 1. The Counter Duration setting,
applicable to sequencer set 0 and defining the maximum Counter 2 count, is also found to be
1. Accordingly, the Counter 2 count related to sequencer set 0 has already reached its maximum
and must start again with the next frame acquisition.
When the next frame start trigger signal was received sequencer set 1 is loaded into the active
set and is used for the image acquisition. The image data are processed and transmitted out of
the camera.
Sequencer set 1 was loaded because the Counter 2 count for sequencer set 0 was found to
already have reached its maximum allowed value in the preceding frame acquisition.
The current frame start trigger count of Counter 2 is found to be 1. The Counter Duration setting,
applicable to sequencer set 1 and defining the maximum Counter 2 count, is also found to be
1. Accordingly, the Counter 2 count related to sequencer set 1 has already reached its maximum
and must start again with the next frame acquisition.
When the next frame start trigger signal was received sequencer set 2 is loaded into the active
set and is used for the image acquisition. The image data are processed and transmitted out of
the camera.
Sequencer set 2 was loaded because the Counter 2 count for sequencer set 1 was found to
already have reached its maximum allowed value in the preceding frame acquisition.
The current frame start trigger count of Counter 2 is found to be 1. The Counter Duration setting,
applicable to sequencer set 2 and defining the maximum Counter 2 count, is found to be 2. Ac-
cordingly, the Counter 2 count related to sequencer set 2 has not yet reached its maximum and
can therefore can continue counting with next frame acquisition.
When the next frame start trigger signal was received sequencer set 2 was still present in the
active set and is used for the image acquisition. The image data are processed and
transmitted out of the camera.
Sequencer set 2 was used again because the Counter 2 count for sequencer set 2 was found
not to already have reached its maximum allowed value in the preceding frame acquisition.
The current frame start trigger count of Counter 2 is found to be 2. The Counter Duration setting,
applicable to sequencer set 2 and defining the maximum Counter 2 count, is also found to be
2. Accordingly, the Counter 2 count related to sequencer set 2 has now reached its maximum
and must start again with the next frame acquisition.
When the next frame start trigger signal was received sequencer set 3 is loaded into the active
set and is used for the image acquisition. The image data are processed and transmitted out of
the camera.
