One last bit of information deals with the CPU operator panel. Remember that the CPU
does not provide a physical switch for changing modes from STOP to RUN. You use
STEP 7 Basic to change the operating mode for the CPU.
First, you access the online CPU.
The "Online tools" task card provides a variety of tools for monitoring the performance of
the CPU, such as the diagnostic buffer, measurements of scan time and memory usage,
and the CPU operating panel.

1. Expand the "Online access" folder and expand the
network adapter that connects to the CPU.
2. Double-click "Update accessible nodes" to find your
CPU.
3. After STEP 7 Basic displays the CPU, expand the CPU.
4. Double-click "Online & diagnostics" to display the online
tools.
Use the CPU operator panel to change the operating mode.
Click the "RUN" or "STOP" buttons to change the operating
mode of the CPU.
Be careful! Clicking the "MRES" button performs a memory
reset and deletes the work memory of the CPU! (While the
MRES does not delete the user program, the non-retentive
memory areas are set to the default configuration for the CPU.)
There is more to learn, but you should now have a foundation in the
skills you need to start creating your own projects.
