the cpu 417-4 has:

• powerful processor:
  the cpu achieves instruction execution times as low as 0.018 µs per binary instruction.
• 30 mb ram （of which 15 mb each for program and data）;
  fast ram for parts of the user program relevant to execution.
• flexible expansion:
  up to 262144 digital and 16384 analog inputs/outputs.
• multi-point interface mpi:
  with the mpi it is possible to establish simple networking of max. 32 stations at a data transmission rate of up to 12 mbit/s. the cpu can establish up to 44 connections to stations of the communications bus （c bus） and the mpi.
  note:
  if the profibus dp interface and mpi interface are operated simultaneously, it is only possible to connect the following bus connector to the mpi interface:
  • with socket: 6es7 972-0bb41-0xa0
  • without socket: 6es7 972-0ba41-0xa0
• mode selector switch:
  designed as toggle switch.
• diagnostics buffer:
  the last 120 fault and interrupt events are retained in a ring buffer for diagnostic purposes （extendable）.
• real-time clock:
  the date and time are appended to diagnostic messages of the cpu.
• memory card:
  for expansion of the integrated load memory. the information in the load memory comprises s7-400 parameterization data in addition to the program and therefore requires twice as much memory space. the result is:
  • the integral load memory is not sufficient for large programs, therefore a memory card is frequently required.
    ram and feprom cards （feprom for retentive storage） are available
• profibus dp interface:
  the profibus dp master interface allows a distributed automation configuration offering high speed and ease of use. from the user's point of view, the distributed i/o is treated as central i/o （same configuring, addressing, and programming）.
  mixed configuration: simatic s5 with simatic s7 as profibus master to en 50170.
  note:
  if the profibus dp and mpi interface are operated simultaneously, it is only possible to connect the following bus connectors to the mpi interface:
  • with socket: 6es7 972-0bb41-0xa0
  • without socket: 6es7 972-0ba41-0xa0
• two additional slots:
  two additional profibus dp master systems can be connected via if 964-dp interface modules.
