Example of configuration control
This example describes a configuration consisting of a CPU and three I/O modules.The
module at slot 3 is not present in the first actual installation, so you use configuration control
to "hide" it.
In the second installation, the application includes the module that was initially hidden but
now includes it in the last slot. A modified control data record provides the information about
the slot assignments of the modules.
Example: Actual installation with configured but unused module
The device configuration contains all modules that can be present in an actual installation
(maximum configuration). In this case, the module that is in slot 3 in the device configuration
is not present in the real installation.
