1 Introduction
Advantages
The solution presented here offers the following advantages:
The illustrations and explanations included in this application example save
you time and costs when commissioning your own automation solution.
You can expand the supplied hardware configuration as required or integrate it
into your project.
By using the ASM 456, the MV420 / MV440 can be integrated into a control
system via PROFIBUS. This is a frequent requirement when migrating older
automation solutions.
The use of the ready-to-use Ident blocks significantly simplifies operating the
SIMATIC MV code readers.
The SIMATIC MV code reader can be operated using a drag chain-compatible
cable between the ASM 456 and the MV.
The configuration as technology object simplifies commissioning substantially.

A reset (initialization) through the Ident blocks sets the MV code reader to ready for
operation. When the reset has been successfully performed, the user can choose
between different MV operations and monitor their status.
