CPU 416F Siemens

Область применения



The CPU 416F-2 and the CPU 416F-3 PN/DP are high-performance CPUs of the SIMATIC S7-400. They allow a fail-safe automation system to be constructed for plants with increased safety requirements.

The integrated PROFIBUS DP interfaces of CPU 416F-2 support direct connection to the PROFIBUS DP fieldbus as a master or as a slave.

Another DP master system can be connected in the case of the CPU 416F-3 PN/DP through the IF 964-DP interface module.

The integrated PROFINET interface of the CPU 416F-3 PN/DP implements switch functionality by using the ERTEC 400 ASIC. This forms the basis for provision of 2 externally accessible PROFINET ports. This means that apart from hierarchic network topologies, line structures can also be implemented with the new S7-400 controllers.

Note:
Only interface module 6ES7964-2AA04-0AB0 can be used.

Fail-safe I/O modules can be connected to all integrated interfaces, to IF 964-DP and/or through communication modules (CP443-5 Ext. and CP443-1 Advanced). Safety-related communication is performed over PROFIBUS DP with the PROFIsafe profile.

Функции

  • Distributed intelligence in Component Based Automation (CBA) on PROFINET
  • Additional diagnostic option with integrated web server

Parameterizable properties

Using the STEP 7 hardware configuration tool, properties and responses of the S7-400 including the CPUs can be parameterized, e.g.:

  • MPI multi-point interface:
    • Determining station addresses.
    • Start-up/cyclic response.
    • Determining the maximum cycle time and communication load.
  • Address assignment:
    Addressing the I/O modules.
  • Retentive areas:
    Determining the number of retentive bit memories, counters, timers, data blocks and clock bit memories
  • Size of the process image, local data.
  • Length of the diagnostic buffer.
  • Protection level:
    Specifying the access rights to program and data.
  • System diagnostics:
    Determining handling and scope of the diagnostic alarms.
  • Cyclic interrupts:
    Setting of periodicity

CPU 416F-3 PN/DP additionally:

  • PROFINET interface
  • Parameterization of time synchronization with NTP procedure

Information and display functions

  • Status and error LEDs:
    LEDs indicate, for example, internal and external errors and operating states such as RUN, STOP, start-up and test functions.
  • Test functions:
    The PG is used to indicate signal states during program execution, to modify process variables independently of the user program, to output the contents of stack memories, to execute individual program steps, and to block program sections.
  • Information functions:
    The PG can be used to obtain information about the memory capacity and operating mode of the CPU and the current loading of the work and load memory.

Communication

The safety related and standard communication between the central controller and the fail-safe ET 200 modules takes place over PROFIBUS DP and/or PROFINET. The specially developed PROFIBUS profile PROFIsafe 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 416F-2 and CPU 416F-3 PN/DP.

Programming

The CPU 416F-2 and the CPU 416F-3 PN/DP are 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 functions 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 configuring the safety-related application without having to use additional tools. The STEP 7 option package "SIMATIC S7 Distributed Safety" is required for programming the safety-related program sections. The package contains all the functions and blocks required to create an F program.
