System overview
3.3 SIMATIC Drive Controller functions
Example: Production cell with access protection
Automation task:
A laser scanner monitors access to a production area. The maintenance area is secured by
a protective door. Entering the production area or opening the protective door, just like an
emergency stop, results in the shutdown or stopping of the production cell.

Feature:
Start-up of the system is only possible with unlocked emergency stop, closed protective door
and free protection area of the laser scanner. After activating the emergency stop, opening
the protective door or addressing the protection area, a user acknowledgement is required to
restart production operations again. Access protection to the F-CPU and the safety program
is essential for productive operation.
Solution:
Use of a SIMATIC Drive Controller with SINAMICS Integrated and failsafe modules in the ET
200SP distributed I/O system on the PROFINET IO.
Programming is done in the TIA Portal. The CPU of the SIMATIC Drive Controller runs a
machine application with motion control and a safety program.
The ET 200SP F modules are used to connect emergency stop, protective door monitoring,
access area monitoring and user acknowledgement. When the safety function is triggered
(e.g. opening the protective door), the programmed stop reaction is triggered for the drives in
the production cell.
