15.5.2.5 Group: Trigger data
This group is used to transfer the data that will be assigned to the next trigger. Variants are available with
payload capacities of 4/8/16/32/64/128 bytes. You should choose the smallest possible variants for the
volume of data you expect to handle. An unnecessarily large selection reduces overall system performance.
It is used in the same way as the TD command in the process interface for FTP and in the results datagram,
the only difference being that new trigger data does not automatically trigger image acquisition. Here, image
acquisition must be triggered with an additional trigger.
If the data is not deleted (payload length
0), the data is used for each new image acquisition thereafter.
