Configuration Control (Option Handling) - Siemens SIMATIC ET 200SP System Manual

Configuration control (option handling)

Introduction
Configuration control (option handling) is used to operate various standard machine
configuration levels in one project without changing the configuration or the user program.
Operating principle of configuration control
You can use configuration control to operate different standard machine configurations with
a single configuration of the ET 200SP distributed I/O system.
● 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. A station option
uses, for example, only some of the configured modules of the station master and these
modules are inserted in the slots in a different order.
● 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.
You use a control data record you have programmed to notify the CPU/interface module as
to which modules are missing or located on different slots in a station option as compared to
the station master. The configuration control does not have an impact on the parameter
assignment of the modules.
Configuration control allows you to flexibly vary the centralized/distributed configuration. This
is only possible if the station option can be derived from the station master.
