Number of traces
The trace quantity structure allows the recording of up to 8 individual channels. The recordings
are directly saved to the drive, and when required, can be read out and permanently saved using
the engineering system (ES). As a result, the trace function is suitable for recording and
monitoring highly dynamic processes. The recorded values are overwritten when the trace
function is reactivated.

The signals to be recorded, the recording time and the trigger conditions are defined in the trace
configuration.
If an online connection exists, you transfer the complete trace configuration from the PG/PC to the
device.
The transfer can also be started offline. When starting the transfer, a connection dialog is opened
via which the online connection can be activated.
If the trace configuration is activated, then the recording is carried out independent of the PG/PC.
The recording is started in the device as soon as the trigger condition has been fulfilled.
When you save the measurement, then the measurement is saved to the opened PG/PC project.
Saving the measurement is independent of when the measurement was actually made.
After the measurement has been saved in the PG/PC, it can be displayed and evaluated there. From
the PG/PC, you can export the measurement data as file - and subsequently import it again.
