● With "On NCK", the recorded data is saved in the NC work memory until the recording is stopped.
Only then is the session file saved on the CompactFlash card.
● With "CF card" or "On hard disk", the data is saved during the recording on the CompactFlash card
or hard disk (e.g. of the PCU). As a consequence, more signals can be processed.

reached.

via the "Insert variable" or "Quick list" softkey.
● Condition and value
After the session has been activated, this defines at which value the trace
recording is exited.
The following values are offered: = =, ≠, >, >=, <, <=, ascending, descend‐
ing, changed.
● Delay time [s]
This defines how long the trace still runs after the session has been exited.
● Overwrite at memory
limit (KB)
Defines from which memory limit the data is overwritten (ring buffer).
