应用

设计

Both CPUs are equipped with the following:

Powerful processor:
The CPUs achieve instruction execution times as low as 0.03 µs per binary instruction.

CPU 416-2: 5.6 MB RAM (of which 2.8 MB each for program and data);
CPU 416-3: 11.2 MB RAM (of which 5.6 MB each for program and data);
CPU 416-3 PN/DP: 11.2 MB RAM (of which 5.6 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 CPUs can establish up to 44 connections to stations of the communications bus (C bus) and the MPI.

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. The number of entries can be parameterized.

Real-time clock:
The date and time are appended to diagnostic messages of the CPU.

Memory card:
For expansion of the integrated load memory. RAM and FEPROM cards (FEPROM for retentive storage) are available

Combined MPI/DP interface and integrated PROFIBUS DP interface (CPU 416-2 and CPU 416-3):
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 and SIMATIC S7 as PROFIBUS master according to EN 50170.

CPU 416-3 and CPU 416-3 PN/DP also include:

A module slot:
An additional PROFIBUS DP master system can be connected via the IF 964-DP interface module.

CPU 416-3 PN/DP additionally includes:

PROFINET interface with 2 ports (switch):

PROFINET I/O, 256 IO devices connectable
