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
  • PROFINET CBA

西门子CPU416-3功能：

• Block protection:
  A password concept protects the user program from unauthorized access.
• Integral HMI services:
  The user only has to specify the source ａnd destination of the data with HMI devices. The data are then transported cyclically ａnd automatically by the system.
• Integrated communications functions:
  • PG/OP communication
  • Shared data communication
  • S7 standard communication
  • S7 communication
• Firmware ｕpdate using network

CPU 416-3 PN/DP additional:

• Open communication over TCP/IP, UDP ａnd ISO-on-TCP （RFC1006）
• Distributed intelligence in Component Based Automation （CBA） on PROFINET
• Additional diagnostic options with integrated web server

Parameterizable attributes

The STEP 7 tool "Hardware Configuration" can be used to program the properties ａnd response of the S7-400 including the CPUs, e.g.

• Multi-point interface MPI:
  • Definition of station addresses.
  • Startup/cycle behavior
  • Stipulation of the maximum cycle time ａnd communications load
• Address assignment:
  Addressing of I/O modules.
• Retentive ranges:
  Definition of the number of retentive bit memories, counters, timers, data blocks ａnd clock memories.
• Size of the process image, local data.
• Length of the diagnostics buffer
• Protection level:
  Definition of access authorization for program ａnd data
• System diagnostics:
  Definition of the handling ａnd scope of diagnostic messages
• Timed interrupts:
  Setting of periodicity

CPU 416-3 PN/DP additional:

• PROFINET interface
• Parameterization of time synchronization using NTP procedure

Indication ａnd information functions

• Status ａnd error indicators:
  LEDs indicate internal ａnd external errors ａnd operating states such as RUN, STOP, Restart, Test function, for example
• Test functions:
  The programming device can be used to display signal states in program execution, modify process tags irrespective of the user program, read out the contents of stack memories, run separate program steps ａnd inhibit program components
• Information functions:
  The programming device can be used to provide the user with information on the memory capacity ａnd operating mode of the CPU ａnd the current utilization of the working ａnd load memories
