Trace element data
The recorded values can be read with the SIWATOOL FTA and exported to
MS Excel or text file.
If the trace function is defined for recording to circulating memory, it can be used
for constructing a status recorder. The command for starting the recording can
come from the SIMATIC control program and the command for stopping can also
come from the control program, e.g. if you want to record and save the progress of
a procedure.
