Application

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.

Design

The CPU 317F-2 PN/DP is equipped with the following:

  • Microprocessor:
    The processor achieves an execution time of approximately 25 ns per binary instruction and 160 ns per floating-point operation.
  • Memory:
    1.5 MB high-speed work memory for safety-relevant and standard program sections; increased memory space requirements must be expected (5 times larger) if safety-relevant program sections are implemented. SIMATIC Micro Memory Cards (max. 8 MB) as load memories for programs additionally permit storage of the project (including symbols and comments) in the CPU.
  • Flexible expansion capability:
    Max. 32 modules, (4-tier configuration)
  • Combined MPI/DP interface:
    The first MPI/DP integrated interface can establish as many as 16 connections simultaneously to S7-300/400 or connections to PG, PC, OP. Of the connections, one is permanently reserved for programming devices and one for OPs.
    The MPI supports simple networking of up to 32 CPUs over “Global data communication”.
    This interface can be reconfigured from MPI interface to DP interface. The DP interface can be used as a DP master or as a DP slave.
    PROFIBUS DP interface:
    The PROFIBUS DP V1 standard is fully supported. This increases the scope of DP V1 standard slaves in terms of diagnostics and parameterization capability.
  • Ethernet interface:
    The second integral interface of the CPU 317F-2 PN/DP is a PROFINET interface with 2-port switch based on Ethernet TCP/IP. It supports the following protocols:

    • S7 communication for data communication between SIMATIC controllers;
    • PG/OP communication for programming, startup and diagnostics through STEP 7;
    • PG/OP communication for interfacing to HMI and SCADA;
    • Open TCP/IP communication over PROFINET and SIMATIC NET OPC server for communication with other controllers and I/O devices with a separate CPU.
