Appendix E: Application Example

In the applications illustrated below, values are for example purposes only.
Note:
You can use this example as setup references. Enter the values in the parameter tables to
select the corresponding functions.
Configure the basic settings using the Quick Start wizard parameters. (These parameters
are inter-related, and changes take effect only after you select YES in step 7 to apply
changes.)
In each example, after performing a Quick Start, navigate to the other required
parameters (either via the handheld programmer, or via SIMATIC PDM) and enter the
appropriate values.
