Meaning
The session is activated by pressing the "Start trace" softkey.
The session is activated using a variable. The variable is selected from a
list using the "Insert variable" softkey.
After the session has been activated, this defines at which value the trace
recording is initiated.
The following values are listed in a combo box:
= =, ≠, >, >=, <, <=, ascending, descending, changed.
Defines whether the recorded data are saved on the CompactFlash card
or in the NC work memory.
For "NCK", the recorded data are saved on the NCU until the recording is
stopped. Only then is the session file saved on the CompactFlash card.
For "On hard drive", the trace unloads the data to the CompactFlash card
while recording. As a consequence, more signals can be processed.
The trace session is stopped by pressing the "Stop trace" softkey.
Defines the time period which after it has expired, the trace recording is
exited.
You can select from the following time periods:
Milliseconds, seconds, minutes, hours, days
The trace session is exited if the specified data quantity (Kbytes) is
reached.
The session is deactivated using a variable. The variable is selected from
a list using the "Insert variable" softkey.
After the session has been activated, this defines at which value the trace
recording is exited.
The following values are listed in a combo box:
= =, ≠, >, >=, <, <=, ascending, descending, changed.
This defines how long the trace still runs after the session has been
exited.
Defines from which memory limit the data is overwritten (ring buffer).
