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.
Design
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
Functions
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)

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
