The CPU 1518F-4 PN/DP is the most powerful S7-1500 CPU with a very large program and data memory for demanding standard and fail-safe 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 1518F-4 PN/DP is used as a PROFINET IO controller or as distributed intelligence (PROFINET I-Device). The integrated PROFINET IO IRT interface is designed as a 2-port switch so that a linear topology can be set up in the system. The additional integrated PROFINET interfaces with separate IP address can be used for network separation, for example.

Distributed I/O can be connected via PROFIBUS (or PROFIsafe) 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.

The CPU 1518F-4 PN/DP features:

  6 MB for program, 20 MB for data
• SIMATIC Memory Cards as load memory; 
  permit additional functions such as datalog and archives
• Flexible expansion options 
  Single-tier configuration with max. 32 modules (CPU + 31 modules)
• Screen with functions for the
  • displaying overview information such as IP address of the integrated interface, station name, plant designation, location identifier, etc.
  • displaying safety mode, overall signature and date of the last download with signature change
  • Display of diagnostic information
  • Display of module information
  • Showing display settings
  • Setting IP addresses
  • Setting date and time
  • Selection of operating mode

  • Display of safety mode, overall signature and date of the last download with signature change.
• PROFINET IO IRT interface for connecting distributed I/O via PROFINET
• 2 PROFINET interfaces for network separation
• PROFIBUS DP interface for connecting distributed I/O via PROFIBUS
• Supports PROFIsafe in centralized and distributed configuration

• 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. Additional PROFINET interface integrated, e.g. for network separation.
• 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
  • Trace functions for all CPU variables, both for diagnostics in real time as well as for sporadic error detection

• 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 for showing overview information:
    e.g. station name, plant identifier, location designation, etc., diagnostic information, module information, display settings.
  • Possible operator control options 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 into 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)
