Group Processing
A group is defined by the trigger type configuration of consecutive logical channels. The first channel of
the group has the trigger type set to software trigger only, hardware or software trigger or idle trigger. If
the following channel trigger type is not set to preceding logical channel conversion completion, the group
consists of only one channel. Otherwise, the group continues until the last channel in a row having trigger
type set to preceding logical channel conversion completion. After the first channel of the group is
triggered and converted, automatically the second channel is triggered and so on until the whole group is
converted.
Figure 3-4 Group Configuration Examples
Figure 3-4 shows some possible group configurations:
a) In the example two groups are configured, the group 1 consists of logical channels 0, 1 and 2 and the
group 2 includes logical channels 3, 4 and 5. If both groups are triggered (trigger status is set for the
starting channels 0 and 3), the group 2 would be converted first due to higher priority setting. Since the
first channel in the groups has the highest priority, the groups are "re-triggerable" (if the next starting
channel trigger appears before the group conversion is finished, the conversion of the group would be
restarted).
b) Here the first channel of the groups has a lower priority then the remaining channels within the groups,
hence it is not possible to re-trigger the group processing. The processing of the group 2 can be started
only by the software trigger of the logical channel 3. The group 1 allows the triggering by the software or
hardware trigger of the channel 0.
c) This example contains three groups, where the group 2 consists of only one logical channel 3. The
group 3 shows the configuration of the group starting with the idle trigger type, i.e. the trigger status of the
logical channel 4 is set to "1" if there is no logical channel having trigger status flag set and inactive data
protection function.
