10cm distance between cables higher 110V if not isolate with i.e

grounded metal plate, if not possible use FO!

High Baudrates, no Spurlines, no Cables shorter 1m

Segment length depends on Baudrate!!

Maximum 244 bytes input and 244 bytes output per slave.

Slave configuration and parameters are set from the master side.

Introduction

PROFINET – The future is green

Trang 10

Industry Sector

PROFINET is the open Industrial Ethernet standard

from PROFIBUS & PROFINET International (PI), Vendor neutral

PROFINET is based on Industrial Ethernet

PROFINET utilizes TCP/IP and IT-Standards

PROFINET is Real-Time Ethernet

PROFINET allows seamless integration

of fieldbus systems

The answer - PROFINET

Trang 11

Industry Sector

Just imagine:

a PROFIBUS installation with…

…wireless communication

…fail-safe communication also via wireless connections

How would PROFIBUS solve those requirements of today’s applications?

…more than one Master in the same bus segment

…web server features

…electrical ring installation

…more than 126 connections/participants on the same bus

…graphic visualization and automatic recognition of the topology

…addressing by name, also automatically possible

…very high transmission rate over large distances, without use of separated Repeaters

…large amount of data (e.g database, images, file transfer) via the same cable for devices

…full access, even remotely, to the entire network

…easy energy management

- New methods of Programming

…and this is increasing the costs…

Wrong!

- A switch in on board of the IO modules!

- IO-Modules with a PROFINET Interface are exactly the same costs as on PROFIBUS

and only the head module needs to be changed, the IOs can be kept!

- PROFINET CPUs are used for Industrial Ethernet communication anyways

- The user program can be kept, there is no difference between PROFIBUS and

PROFINET IO-Access!

- Even Redundancy is possible directly on the Products, no OLM, no FO!!
