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 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 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

• PROFINET CBA
