15.4.15 TD command
– request image acquisition and transfer data
This function enables you to immediately acquire an image and response datagram. The response datagram
will only be sent if the result is automatically sent following image evaluation and if the data is defined.
Unlike with command TR, this function can be used to transfer a string with the trigger, for example the part
number of the current item being checked. The device allows you to use this string in the file name for the
image when saving it to an FTP server. This is an easy way to establish a connection between images and
objects.
