Project trace
A project trace contains trace configurations of multiple devices and records the signals
across devices.
A global trigger, which can be activated by each device, is used for the synchronization. After
receiving the global trigger, the devices with a valid project trace configuration start
recording.
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
You can find additional information on the test functions in the STEP 7 online help.
Additional information about testing with trace functions is available in the Function Manual
