Testing with the LED flash test
In many online dialogs, you can perform an LED flash test. This function is useful, for
example, when you are not sure which device in the hardware configuration corresponds to
the station currently selected in the software.
When you click the "Flash LED" button, an LED flashes at the currently selected station. On
the CPU, the following LEDs flash: RUN/STOP LED, ERROR LED and MAINT LED. The
LEDs flash until you cancel the flash test.
Testing with a trace function
The trace function is used to record the CPU tags, depending on the settable trigger
conditions. Tags are, for example, drive parameters or system and user tags of a CPU. The
CPU saves the recordings. You can display and evaluate the recordings, if necessary, with
STEP 7 or via the Web server.
The trace function can be called from the CPU's folder in the project tree, under the name
"Traces".
In connection with trace functions, please also note the following FAQ on the Internet

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".
Reference
Additional information on the test functions can be found in the STEP 7 online help.
