Configuration control (option handling)
Distributed I/O system
168 System Manual, 09/2019, A5E03576849-AJ
Advantages
● Simple project management and commissioning by using a single STEP 7 project for all
station options.
● Simple handling for maintenance, versioning and upgrade:
● Hardware savings: Only those I/O modules are installed that are required for the
machine's current station option.
● Savings potential in the creation, commissioning and the documentation for standard
machines.
● Simple station expansion by using pre-wired empty slots. To expand, you simply
exchange the BU cover for the new model. You can find further information on this in
section Examples of configuration control (Page 187).
Procedure
To set up the configuration control, follow these steps:
Enable configuration control in STEP 7
Section Configuring (Page 169)
Create control data record
Section Creating the control data record (Page 171)
3 Transfer control data record Section Transferring the control data record in the startup
program of the CPU (Page 182)
Library for configuration control
A library for configuration control is available on the Internet for download
(https://support.industry.siemens.com/cs/#document/29430270?lc=en-WW
). The library
contains data types with the structure of the control data records for the ET 200SP
distributed I/O system. You can implement your flexible automation solution inexpensively
with the help of these data types.
Note
Configuration control in the case of motor starters
"M
anual local" mode is possible in the case of motor starters when configuration control is
active. The motor starter works with the last valid parameters. Do not change the
parameterization while "manual local" mode is active.
