S7-1500 Central processing units

The central processing units (CPUs) are the heart of the SIMATIC S7-1500. They execute the user program and network the controller with other automation components.
Thanks to multiple innovations, the new Controller will provide the ultimate “plus” in productivity and efficiency.

The following CPUs are available:

CPU 1511-1 PN / CPU 1511F-1 PN for small to medium demanding standard and fail-safe applications

CPU-1511C-1 PN for small to medium standard applications with space-saving requirements,
such as in series machine manufacturing

CPU-1512C-1 PN for medium standard applications with space-saving requirements,
such as in series machine manufacturing

CPU 1513-1 PN / CPU 1513F-1 PN for medium demanding standard and fail-safe applications

CPU 1515-2 PN / CPU1515F-2 PN for medium to exceptionally demanding standard and fail-safe applications

CPU 1516-3 PN/DP / 1516F-3 PN/DP for exceptionally demanding standard and fail-safe applications and additional communication tasks

CPU 1517-3 PN/DP / 1517F-3 PN/DP for demanding standard and fail-safe applications and additional communication tasks

CPU 1518-4 PN/DP / 1518F-4 PN/DP for fail-safe and standard high-performance applications and shortest reaction times

CPU 1518 ODK for fail-safe and high-performance applications with the option to program C/C++ Code via ODK.
