2	NOTES REGARDING THE USAGE OF CPU 315F-2 PN/DP

The CPU 315F-2 PN/DP is a CPU that is shipped with 2 integrated interfaces.

-The first interface is a combined MPI/PROFIBUS DP interface that can be used at the PROFIBUS DP as master or slave to connect distributed IO/field devices with very fast reaction time.

In addition, it is possible to program the CPU here by means of an MPI or PROFIBUS DP

-The second interface is an integrated PROFINET interface.

This allows for using the CPU as PROFINET IO controller to operate distributed IO on PROFINET. The CPU can be programmed by means of this interface also!

-Moreover, it is possible to use fail-safe IO devices on both interfaces.

Notes:

-In module E11, the CPU 315F-2 PN/DP is used as the controller for the data exchange of a SIMATIC RFID system on the PROFINET.

-To run this CPU, a micro-memory card is required!

-The addresses of the input and output modules can be parameterized at this CPU.
