CPU 416-3 PN/DP 中集成了 PROFINET 功能
应用
CPU 416-2, CPU 416-3 and CPU 416-3 PN/DP are powerful SIMATICS7-400 CPUs.
The integrated PROFIBUS DP interfaces in the CPU 416-2 and CPU416-3 make it possible to connect directly to the PROFIBUS DPfieldbus as a master or slave.
An additional DP master system can be connected to the CPU 416-3and CPU 416-3 PN/DP using the IF 964-DP interface module.
The integrated PROFINET interface of the CPU 416-3 PN/DP includesswitch functionality when the ERTEC 400-ASIC is used. This formsthe basis for providing two externally accessible PROFINET ports.In addition to hierarchical network topologies, this also enablesthe creation of line structures in the new S7-400 controllers.
Note:
Only the 6ES7 964-2AA04-0AB0interface submodule may be used.
设计
Both CPUs are equipped with the following:
Powerful processor:
The CPUs achieve instruction execution times as low as 0.03 µs perbinary instruction.CPU 416-2: 5.6 MB RAM (ofwhich 2.8 MB each for program and data);
CPU 416-3: 11.2 MB RAM (ofwhich 5.6 MB each for program and data);
CPU 416-3 PN/DP: 11.2 MBRAM (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. TheCPUs can establish up to 44 connections to stations of thecommunications 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 ringbuffer for diagnostic purposes. The number of entries can beparameterized.Real-time clock:
The date and time are appended to diagnostic messages of theCPU.Memory card:
For expansion of the integrated load memory. RAM and FEPROM cards(FEPROM for retentive storage) are availableCombined MPI/DP interface and integrated PROFIBUS DP interface(CPU 416-2 and CPU 416-3):
The PROFIBUS DP master interface allows a distributed automationconfiguration offering high speed and ease of use. From the user'spoint of view, the distributed I/O is treated as central I/O (sameconfiguring, addressing and programming).
Mixed configuration: SIMATIC S5 and SIMATIC S7 as PROFIBUS masteraccording 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 viathe 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
