There are two ways to synchronize the internal time of the device with the system time
of the controller:
•
Via telegram: The computer queries the internal time of the device using a tele‐
gram. The device writes its internal time in a telegram and sends this to the
computer. Sending can happen with a delay time of up to a few milliseconds,
which results in some uncertainty.
•
Via index (pulse at hardware output): The device outputs a signal depending on
the sender/receiver position. This signal is used, for example, to synchronize scans
with the position of a swivel device for 3D measurement.
