Migration Guide: S7-31xT to S7-1500(T)

  • Entry
  • Associated product(s)
The aim of the migration guide is to support users of the Technology CPU 31xT-2 DP / Technology CPU 31xT-3 PN/DP in migrating to the new CPUs of the S7-1500 and S7-1500T series.

For executing motion control functionalities, Siemens currently offers the following SIMATIC CPU series:

  • SIMATIC S7-1500 CPUs
    SIMATIC S7-1500 CPUs are SIMATIC standard CPUs. They all have selected integrated motion control functions and can therefore be directly used for simple motion control applications without additional hardware and software.
  • SIMATIC S7-1500T CPUs
    SIMATIC S7-1500T CPUs are SIMATIC CPUs that are specifically tailored to the requirements of higher-quality motion control applications and have a greater range of motion control functions than SIMATIC standard CPUs.
    Using these CPUs in TIA Portal does not require additional software. S7-1500T CPUs are fully integrated in the TIA Portal engineering framework.

The migration guide provides users of the previous motion control CPU, Technology CPU 31xT-2 DP / Technology CPU 31xT-3 PN/DP, with a reference document that allows them to transfer existing user programs and applications to SIMATIC S7-1500(T) CPUs. The guide mainly focuses on showing the system differences between the S7-300T and S7-1500(T) controller families, a selection aid that helps the user choose between SIMATIC S7-1500 CPUs and SIMATIC S7-1500T CPUs based on the technological requirements of an application and on showing the differences between the technology functions (PLCopen blocks) of the S7-300T and the S7-1500(T), which supports transferring the user program to TIA Portal or the new controller family.
However, the migration guide can also provide useful information for those new to the world of SIMATIC Motion Control who meet the SIMATIC S7-1500 / SIMATIC S7-1500T controllers for the first time.
