CPU 416-3 PN/DP 中集成了 PROFINET 功能

CPU 416-2, CPU 416-3 and CPU 416-3 PN/DP are powerful SIMATIC S7-400 CPUs.

The integrated PROFIBUS DP interfaces in the CPU 416-2 and CPU 416-3 make it possible to connect directly to the PROFIBUS DP fieldbus as a master or slave.

An additional DP master system can be connected to the CPU 416-3 and CPU 416-3 PN/DP using the IF 964-DP interface module.

The integrated PROFINET interface of the CPU 416-3 PN/DP includes switch functionality when the ERTEC 400-ASIC is used. This forms the basis for providing two externally accessible PROFINET ports. In addition to hierarchical network topologies, this also enables the creation of line structures in the new S7-400 controllers.

Note:
only the 6ES7 964-2AA04-0AB0 interface submodule may be used.

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
