Overview

高端性能范圍內的高性能 CPU 適用于對性能要求很高的工廠 CPU 416-3 PN/DP 中集成了 PROFINET 功能

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) 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，
