Application

A range of fail-safe, performance-graded CPUs are available for the SIPLUS S7-1500:

  • SIPLUS CPU 1511F-1 PN:
    the cost-effective entry-level CPU for standard and fail-safe applications with medium requirements in terms of processing performance and response speed in discrete production technology.
  • SIPLUS CPU 1513F-1 PN:
    the CPU with a medium to large program and data memory for standard and fail-safe applications that also include distributed automation structures alongside central I/O.
  • SIPLUS CPU 1516F-3 PN/DP:
    for applications with medium/high requirements for program scope and processing speed, for distributed setup via PROFINET IO and PROFIBUS DP with PROFIsafe.
  • SIPLUS 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.
