6.9 Utilities for Configuring and Assigning Parameters to an
S7-400 Assembly
Introduction
One task involved in configuring a plant is assigning parameters to the hardware of
the automation system. Increasingly complex automation tasks require more and
more effort to configure.
Configuration with STEP 7
STEP 7 provides system software to help you configure and assign parameters to
your plant. It is characterized by easy handling (selection, setting marks and filling
out dialog forms).
You can also use STEP 7 to configure modules such as CPUs and FMs. Modules
are selected from an electronic catalog. The configuration and parameter
assignment data are transferred to the CPU and automatically distributed to the
individual modules at startup.
If you do not specify special values, the system automatically starts up with its
default settings. In other words, parameter assignment is possible but not
necessary.
