The CPU 417-4 is the most powerful SIMATIC S7-400 CPU. The integral PROFIBUS DP interfaces permit direct connection to the PROFIBUS DP fieldbus as master or slave.
Two further DP master systems can be connected via the IF 964-DP interface submodules.
Note:
Only the interface module 6ES7 964-2AA04-0AB0 can be used.
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
