Configuration
8.5 Configuration control (option handling)
Operating principle of configuration control
You can use the configuration control to operate different expansion levels of a series
machine with a single configuration of the HCS.
● A station master is configured in a project (maximum configuration). The station master
comprises all modules needed for all possible plant parts of a modular standard machine.
● The project's user program provides for several station options for various standard
machine configuration levels as well as selection of a station option. For example, a
station option uses only some of the modules of the station master.
● The standard machine manufacturer selects a station option for a configuration of the
standard machine. To do this, the project need not be modified, and it is not necessary to
load a modified configuration.
Using a custom control data record, you inform the HCS which modules in a station option
are missing or are located in a different slot as compared to the station master. The
configuration control does not have an impact on the parameter assignment of the modules.
The following figure shows 3 expansion levels of a heating control system with the
associated station options.

Advantages
● Simple project execution and commissioning by using a single STEP 7 project for all
station options.
● Easy handling during maintenance, versioning and upgrades:
● Savings potential in the creation, commissioning and the documentation for standard
machines.
