Application

The CPU 1518-4 PN/DP is the fastest S7-1500 CPU with very large program and data memory for demanding tasks in applications that also contain distributed automation structures alongside central I/O. It can be used, for example, as a central controller in production lines or as a machine controller with high processing speed demands.

The CPU 1518-4 PN/DP can be used as a PROFINET IO controller or as distributed intelligence (PROFINET I-Device). The integrated PROFINET IO IRT interface is designed as 2-port switch so that a linear topology can be set up in the system.
Two additional integrated PROFINET interfaces with separate IP address can be used, for example, for network separation. Additional PROFINET IO RT devices can be connected via the PROFINET interface X2 or fast communication can be established in the form of an I-Device. The X3 interface can be used with a transmission rate of 1 Gbit/s, e.g. for communication with the backbone. Distributed I/O can be connected via PROFIBUS via the integrated PROFIBUS interface.

In addition, the CPU offers comprehensive control functionalities as well as the ability to connect drives via standardized PLC-open blocks.

Design

The CPU 1518-4 PN/DP features:

  • A powerful processor:
    The CPU achieves command execution times as low as 1 ns per binary instruction.
  • Large work memory:
    4 MB for program, 20 MB for data
  • SIMATIC Memory Cards as load memory;
    permit additional functions such as datalog and archives
  • Flexible expansion capability:
    single-tier configuration with max. 32 modules (CPU + 31 modules)
  • Display with functions for:
    • Display of overview information such as IP address of the integrated interface, station name, higher level designation, location designation, etc.,
    • Display and acknowledgment of diagnostic and user messages
    • Display of module information
    • Showing display settings
    • Display of a user-definable logo
    • Setting of IP addresses

    • Selection of the operating mode
    • Resetting of the CPU to factory settings
    • Backup and restoring of the project
    • Disabling/enabling of the display
    • Enabling of protection levels
  • PROFINET IO IRT interface and second PROFINET IO RT interface for connecting distributed I/O via PROFINET
  • Three PROFINET interfaces for network separation, for example; PROFINET interface X3 with a data transfer rate of up to 1 Gbit/s
  • PROFIBUS DP interface for connecting distributed I/O via PROFIBUS
Function

  • Performance
    • Faster command processing, depending on the CPU type, language extensions and new data types
    • Even shorter response times of the CPUs due to considerably faster backplane bus
    • Powerful network connection:
      PROFINET IO IRT (2-port switch) as standard interface. Two additional PROFINET interfaces integrated, e.g. for network separation. Additional PROFINET IO RT devices can be connected via the PROFINET interface X2 or fast communication can be established in the form of an I-Device. The X3 interface can be used with a transmission rate of 1 Gbit/s, e.g. for communication with the backbone
  • Integrated technology
    • Connection of analog and PROFIdrive-capable drives via standardized blocks (PLCopen)
    • Support of speed-controlled and positioning axes as well as external encoders, precise position gearing between axes
    • Trace functions for all CPU tags, both for diagnostics in real time as well as for sporadic error detection; can also be called via the web server of the CPU
    • Comprehensive control functionalities, e.g. easily configurable blocks for automatic optimization of the control parameters for optimum control quality
  • Security Integrated
    • Password-based know-how protection against unauthorized reading 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.

      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

  • 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)
