SIMATIC S7-300 CPU317F-2 PN/DP, CENTRAL PROCESSING UNIT WITH 1.5 MBYTE WORKING MEMORY, 1. INTERFACE MPI/DP 12MBIT/S, 2. INTERFACE ETHERNET PROFINET, WITH 2 PORT SWITCH, MICRO MEMORY CARD NECESSARY

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.
Function

  • Password protection;
    a password concept protects the user program from unauthorized access.
  • Diagnostics buffer;
    the last 500 error and interrupt events are stored in a buffer for diagnostic purposes.
  • Maintenance-free data backup;
    all data is automatically backed up by the CPU if the voltage is interrupted and is available unchanged after the voltage has been reconnected.

Parameterizable properties

The S7 configuration as well as the properties and response of the CPUs can be parameterized using STEP 7:

  • Multi-Point Interface (MPI);
    determination of node addresses.
  • Start-up/cycle time behavior;
    definition of maximum cycle time and loading.
  • Clock memory;
    setting of addresses.
  • Protection level;
    definition of access rights for program and data.
  • System diagnostics;
    definition of handling and scope of diagnostic messages.
  • Watchdog interrupts;
    setting of periodicity.
  • Time-of-day interrupts;
    setting of start date, start time, and periodicity.
  • PROFIBUS DP master/slave interface;
    user-oriented address allocation for distributed I/O.

Display and information functions

  • Status and error indications;
    LEDs indicate hardware, programming, time, I/O or bus errors and operating statuses such as RUN, STOP, start-up.
  • Test functions;
    the PG is used to indicate signal status during program execution, to modify process variables independently of the user program and to output the contents of stack memories.
  • Information functions;
    the PG can be used to obtain information about the memory capacity and operating mode of the CPU, the current loading of the work and load memory, current cycle times and diagnostics buffer content in plain text.

Integrated communication functions

  • PG/OP communication
  • Global data communication
  • S7 basic communication
  • S7 communication
  • Open communication by means of TCP/IP
  • PROFINET CBA
  • Web server
  • Data record routing
Communication

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.

Mode of operation

The safety functions of the F-CPU are included in the F program of the CPU and in the fail-safe signal modules. The signal modules monitor the output and input signals by means of discrepancy analysis and the injection of test signals.

The CPU checks the proper operation of the controller by means of periodic self-tests, command tests and logic-based and time-based program execution checks. Furthermore, the I/O is checked using requests for signs of life.

If an error is diagnosed in the system, the system will be placed in a safe state.

An F runtime license is not required to operate the CPU 317F-2 PN/DP.

Programming

The CPU 317F-2 PN/DP is programmed in the same manner as the other SIMATIC S7 systems. The user program for non-fail-safe plant sections is created using familiar programming tools, e.g. STEP 7.

Option packages SIMATIC S7 Distributed Safety (Classic) and SIMATIC Safety Advanced V12 (TIA Portal V12)

The STEP 7 option packages “SIMATIC S7 Distributed Safety” (Classic) or SIMATIC Safety Advanced V12 (TIA Portal V12) are required for programming the safety-related program sections. The packages contain all the functions and blocks required to create an F program.

The F program with the safety functions is connected in F FBD or F LAD or using special function blocks from the F library. Use of F FBD or F LAD simplifies
configuration and programming of the plant and also acceptance testing thanks to the non-plant-specific uniform presentation form. The programmer can concentrate on configuration of the safety-related application without the need to use additional tools.

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.
