Testing with CPU Trace
The trace function is used to record the CPU tags, depending on the settable trigger
conditions. Examples of tags are the system and user tags of a CPU. Plant states can also
be recorded if the drive parameters have been interconnected with CPU tags using relevant
frames.
The CPU saves the recordings. If necessary, you can display and evaluate the recordings
with STEP 7 or over the Web server. The Trace function can be called from the CPU's folder
in the project tree, under "Traces".
Please also see the following FAQ on the Internet
(https://support.industry.siemens.com/cs/ww/en/view/102781176) relevant for Trace
functions.
Testing with Drive Trace
You use Drive Trace to records the states of a drive and evaluate them using Startdrive. As
the states are recorded in the drive itself (minimum clock 125 µs), Drive Trace is particularly
useful for monitoring highly dynamic processes.
For further information, see the Trace function section in the SINAMICS S120 Startdrive

Simulation
With STEP 7 you can run and test the hardware and software of the project in a simulated
environment. Start the simulation using the menu command "Online" > "Simulation" > "Start".
Further information
Additional information on the test functions can be found in the STEP 7 online help.
