and parameters of your CPU. Now select the "Diagnostic Buffer" tab to determine
the cause of the STOP state.
The latest event (number 1) is at the top of the list. The cause of the STOP state is
displayed. Close all windows except for the SIMATIC Manager.
If a programming error caused the CPU to go into STOP mode, select the event and click
the "Open Block" button.
The block is then opened in the familiar LAD/STL/FBD program window and the faulty
network is highlighted.
With this chapter you have successfully completed the "Getting Started" sample project,
