S7-1500 Standard CPUs Application

Five standard CPUs with differing performance ranges are available for SIMATIC S7-1500:

  • CPU 1511-1 PN:
    for smaller applications with medium requirements on the program scope and processing speed, for distributed setup via PROFINET IO.
  • CPU 1513-1 PN:
    for applications with medium requirements on the program scope and processing speed, for distributed setup via PROFINET IO.
  • CPU 1515-2 PN:
    for applications with medium/high requirements on the program scope, networking and processing speed, for distributed setup via PROFINET IO. The second PROFINET interface with separate IP address can be used for connecting further PROFINET IO RT devices, for high-speed communication as an I-Device, or for network separation.
  • CPU 1516-3 PN/DP:
    for applications with high requirements regarding program scope, networking and processing speed, for distributed setup via PROFINET IO and PROFIBUS DP. The second PROFINET interface with separate IP address can be used for connecting further PROFINET IO RT devices, for high-speed communication as an I-Device, or for network separation.
  • CPU 1517-3 PN/DP:
    for applications with very high requirements regarding program scope and networking, and for very high requirements regarding processing speed, for distributed setup via PROFINET IO and PROFIBUS DP. The second PROFINET interface with separate IP address can be used for connecting further PROFINET IO RT devices, for high-speed communication as an I-Device, or for network separation.
  • CPU 1518-4 PN/DP:
    for applications with extremely high requirements regarding program scope and networking, and for maximum requirements regarding processing speed. For distributed configuration via PROFINET IO and PROFIBUS DP. The PROFINET interface X2 can be used for connecting additional PROFINET IO RT devices or for fast communication as an I-Device. The PROFINET interface X3 gives you the capability of transferring data at a speed of 1 Gbit/s. The two additional integrated PROFINET interfaces with separate IP address can be used for network separation, for example.
  • CPU 1518-4 PN/DP ODK:
    for applications with very high requirements regarding program scope, networking and processing speed and for maximum requirements regarding processing speed. For distributed configuration via PROFINET IO and PROFIBUS DP. The PROFINET interface X2 can be used for connecting additional PROFINET IO RT devices or for fast communication as an I-Device. The PROFINET interface X3 gives you the capability of transferring data at a speed of 1 Gbit/s. The two additional integrated PROFINET interfaces with separate IP address can be used for network separation, for example. The CPU 1518-4 PN/DP ODK allows the execution of functions created with the high-level language C/C++.
