Siemens CPU317F-2PN/DP CPU Unit

Manufacturer: Siemens

Safety-oriented and standard communication between the central controller and distributed stations takes place over PROFIBUS DP and/or PROFINET. The specially developed PROFIsafe profile supports the transfer of user data for the safety functions within the standard data message frame. Additional hardware components, e.g. special safety buses are not required. The necessary software is either integrated in the hardware components as an expansion of the operating system or loaded into the CPU later as a certified software block.

Features Applications Model

Based on CPU 317-2 PN/DP
The fail-safe CPU with a large program memory and quantity framework for demanding Applicaiton; for setting up a fail-safe automation system in plants with increased safety requirements.
Complies with safety requirements to SIL 3 acc. to IEC 61508 and PL e acc. to ISO 13849.1
Fail-safe I/O modules in distributed stations can be connected through the integrated PROFINET interface (PROFIsafe) and/or through the integrated PROFIBUS DP interface (PROFIsafe)
Fail-safe I/O modules of the ET 200M range can also be centrally connected
Central and distributed use of standard modules for non safety-relevant Applicaiton
Component based Automation (CBA) on PROFINET
PROFINET IO Controller for operating distributed I/O on PROFINET
PROFINET interface with 2-port switch
PROFINET proxy for intelligent devices on PROFIBUS DP in Component Based Automation (CBA)
SIMATIC Micro Memory Card required for operation of CPU.

The CPU 317F-2 PN/DP allows a more complex fail-safe automation system to be implemented for plants with increased safety requirements, especially in manufacturing automation.
It can be implemented as a PROFINET IO Controller and as a standard PROFIBUS DP Master in the SIMATIC S7-300. The CPU 317F-2 PN/DP can also be implemented as distributed intelligence (DP slave).
Distributed I/O stations containing fail-safe I/O modules can be connected via the two integrated interfaces. The fail-safe I/O modules of ET 200M can also be installed in central, safety-related configurations.
The safety-oriented communication between the F-CPU and the fail-safe I/O modules is performed on the basis of the PROFIsafe profile.
A SIMATIC Micro Memory Card is required for operation of the CPU.
