Application

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

• CPU  1517F-3 PN/DP: 
  for standard and failsafe applications with very high requirements for program scope networking, and for very high requirements regarding 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 network separation, for example.
