CPU 414F
  • Block protection:
    A password concept protects the user program from unauthorized access.
  • Integrated HMI services:
    In the case of HMI devices, the user only has to specify the source and destination of the data. These are automatically transferred cyclically by the system.
  • Integrated communication functions:
    • PG/OP communication
    • Global data communication
    • S7 basic communication
    • S7 communication
  • Firmware update over the network
  • Open communication over TCP/IP, UDP and ISO-on-TCP (RFC1006)
  • Distributed intelligence in Component Based Automation (CBA) on PROFINET
  • Additional diagnostic option with integrated web server
Parameterizable properties

The STEP 7 tool "Hardware Configuration" can be used to program the properties and response of the S7-400 including the CPUs, e.g.

  • Multi-point interface MPI:
    • Determining station addresses.
    • Startup/cyclic behavior.
    • Definition of maximum cycle time and communication load.
  • Address assignment:
    Addressing of the I/O modules.
  • Retentive areas:
    Definition of the number of retentive bit memories, counters, timers, data blocks and clock memories.
  • Size of the process image, local data.
  • Length of the diagnostic buffer.
  • Protection level:
    Definition of access authorization to program and data.
  • System diagnostics:
    Determination of handling and scope of diagnostics messages.
  • Cyclic interrupts:
    Setting periodicity.
  • PROFINET interface
  • Parameterization of time synchronization with NTP procedure
Display and information functions
  • Status and fault indicators:
    LEDs indicate, for example, internal and external errors and operating states such as RUN, STOP, start-up and test functions.
  • Test Functions:
    The programming device can be used to display signal states in the program execution sequence, modify process variables independently of the user program, output contents of stack memories, run through program steps individually, and disable program sections.
  • Information functions:
    The user can obtain information about the memory capacity and operating mode of the CPU, and the current utilization of the RAM 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 allows the transmission of user data associated with the safety function within the standard data telegram. Additional hardware components, e.g. special safety buses, are not required. The necessary software is either integrated into the hardware components as an expansion, or reloaded into the CPU 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 output and input signals by means of discrepancy analyses and test signal injections.

The CPU checks the proper operation of the controller with regular self-tests, command tests, and logical and chronological program execution checks. In addition, the I/O is checked by means of sign-of-life requests.

If a fault is diagnosed in the system, the system is brought to a safe state.

An F-Runtime license is not required to operate the CPU 414F-3 PN/DP.

Programming

The CPU 414F-3 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 with the field-proven programming tools, e.g. STEP 7.

Option packages SIMATIC S7 Distributed Safety (Classic) andSIMATIC 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 system and also acceptance testing thanks to the cross-system uniform presentation form. Programmers can concentrate fully on the safety-related application without having to use additional tools.
