概述

CPU 1517H-3 PN/FO

• The CPU for applications with high requirements for availability, very high requirements for program scope and networking, and very high requirements for processing speed.
• High processing speed for binary and floating-point arithmetic
• Used as central controller with distributed I/O
• PROFINET IO RT interface with 2-port switch
• Additional PROFINET interface with separate IP address
• PROFINET IO controller for operating distributed I/O on PROFINET

Note:
SIMATIC Memory Card required for operation of the CPU

應用

The CPU 1517H-3 PN is the CPU with an extremely large program and data memory for applications which have higher requirements for availability compared with standard CPUs. It can be used as the PROFINET IO controller. The integrated PROFINET IO RT interface is designed as a 2-port switch, enabling a ring topology to be set up in the system. The additional integrated PROFINET interface with separate IP address can be used, for example, for network separation.

設計

The CPU 1517H-3 PN features:

• A powerful processor:
  The CPU achieves a command execution time as low as 40 ns per binary command.
• Large work memory:
  2 MB for program, 8 MB for data
• SIMATIC Memory Cards as load memory
• Display with functions for:
  • Display of overview information such as station name, higher level designation, location designation, etc.
  • Presenting diagnostic information
  • Display of module information
  • Showing display settings
  • Setting IP addresses
  • Setting date and time
  • Displaying operating mode (redundant or non-redundant)
  • Displaying status (stop, primary or backup)
  • Resetting of CPU to factory settings
  • Disabling/enabling the display
  • Enabling protection levels
• PROFINET IO RT interface for connecting distributed I/O via PROFINET

功能

• Performance
  • Faster command processing, language extensions and new data types depending on the CPU type
  • Even shorter response times of the CPUs due to considerably faster backplane bus
  • Powerful network connection:
    Each CPU is equipped with PROFINET IO RT (2-port switch) as the standard interface.
• Security Integrated
  • Password-based know-how protection against unauthorized read-out and modification of program blocks
  • Copy protection for tying individual blocks to the serial number of the SIMATIC Memory Card: The block can only run if the configured memory card is inserted into the CPU.
  • 4-level authorization concept:
    Communication to the HMI devices can also be restricted.
  • Manipulation protection:
    The controller recognizes changed or unauthorized transmissions of the engineering data.
• Design and handling
  • Display of overview information:
    E.g. Station name, plant identifier, location designation, etc., diagnostic information, module information, display settings.
  • Possible operations on the display:
    set addresses, set date and time, select operating mode of CPU, reset CPU to factory settings, disable/enable display, activate protection levels.
• Integrated system diagnostics
  • System diagnostics information is displayed consistently and in plain text in the display, TIA Portal, HMI devices and Web server, even for messages from the drives, and updated even if the CPU is in STOP mode.
  • Integrated in the firmware of the CPU, no special configuration is required
• SIMATIC Memory Card (required for operation of the CPU)
  • Used as a plug-in load memory or for updating the firmware.
  • Also for storing additional documents or csv files (for recipes and archives)
• Programming of the standard program section
  • Programming with STEP 7 V15.1
