Application

Various failsafe CPUs with graduated levels of performance are available for the SIMATIC S7-1500:

• CPU 1518F-4 PN/DP: 
  for standard and failsafe applications with high requirements for program scope and processing speed, for distributed setup via PROFINET IO and PROFIBUS DP with PROFIsafe. The additional integrated PROFINET interface with separate IP address can be used, for example, for network separation.

Overview

• The CPU with a very large program and data memory in the S7-1500 controller product range for failsafe applications with highest requirements regarding program scope and networking. 
• Can be used for failsafe functions up to SIL 3 according to IEC 61508 and up to PLe according to ISO 13849.
• Extremely high processing speed for binary and floating-point arithmetic. 
• For cross-industry automation tasks in series machine, special machine and plant construction
• Used as central controller in production lines with central and distributed I/O.
• Supports PROFIsafe in centralized and distributed configuration.  
• PROFINET IO IRT interface with 2-port switch. 
• Two additional PROFINET interfaces with separate IP addresses. 
• PROFINET IO controller for operating distributed I/O on PROFINET.
• PROFINET I-Device for connecting the CPU as an intelligent PROFINET device under a SIMATIC or non-Siemens PROFINET IO controller. 
• PROFIBUS DP master interface. 
• Isochronous mode on PROFIBUS and PROFINET. 
• Integrated Motion Control functionalities for controlling speed-controlled and positioning axes, support for external encoders
• Integrated Web server with the option of creating user-defined Web pages.
