The CPU 1517F-3 PN/DP is the CPU with a very large program and data memory for demanding standard and fail-safe applications that also contain distributed automation structures alongside central I/O.

It can be used as a PROFINET IO controller or as distributed intelligence (PROFINET I-Device). The integrated PROFINET IO IRT interface is designed as a 2-port switch so that a linear topology can be set up in the system.

The additional integrated PROFINET interface with separate IP address can be used, for example, for network separation.

Distributed I/O can be connected via PROFIBUS via the integrated PROFIBUS interface.

In addition, the CPU offers comprehensive control functionalities as well as the ability to connect drives via standardized PLC-open blocks.
