5.10.2 Configuration control for IO systems
5.10.2.1 Information about configuration control of IO systems
Configuration control of IO systems makes it possible to generate several concrete versions of
a standard machine from a standard machine project.
You are given the flexibility to vary the configuration of an IO system for a specific application
as long as the real configuration can be derived from the set configuration. The configured
configuration therefore represents the superset of all real configurations that can be derived
from it.
The following figure shows an example of how two IO systems with a different number of
IO devices arise from one standard machine project.
Figure 5-97 Example of configuration control for PROFINET IO systems
In the following sections, you find a description of how to configure and program a PROFINET
IO system to commission, for example, a standard machine on-site without using
configuration software.
