BECKHOFF New Automation TechnologyWe reserve the right to make technical changes.

Fieldbus Components

EtherCAT

EtherCAT (Ethernet for Control Auto mation

Technology) is the Ethernet solution for

industrial automation, characterised by

outstanding performance and particularly

simple handling.

Lightbus

This well proven ﬁ bre optics bus system

from Beckhoff is characterised by par-

ticularly good immunity to EMI, easy

installation and a very fast, cyclic and

deterministic data ﬂ ow.

PROFIBUS

PROFIBUS is widely used as a fast bus

for decentralised peripheral components

(PROFIBUS DP). In addition to PROFIBUS

DP and FMS, Beckhoff also supports

the standard for drive communication,

PROFIBUS MC.

Interbus

Interbus is easy to conﬁ gure, fast and

reliable. The shift register protocol of the

master/slave system offers high efﬁ ciency

in cyclic communication.

CANopen

The effective utilisation of the bus band-

width allows CANopen to achieve a short

system reaction time at comparatively

low data rates. The typical advantages of

CAN, such as high data security and multi-

master capability are retained.

DeviceNet

DeviceNet is a sensor/actuator bus system that

originated in the USA, but which meanwhile

is increasingly being used in Europe and Asia.

DeviceNet is CAN based (Controller Area Net).

ControlNet

ControlNet is an open, standardised ﬁ eldbus

system. The protocol allows both cyclic and

acyclic data to be exchanged over the bus

without affecting each other.

SERCOS interface

SERCOS was originally developed as a fast

ﬁ bre optic bus system for drives. Thanks

to the Beckhoff SERCOS interface Bus Coupler,

the advantages such as high data rate and

short cycle times can now be provided for the

I/O peripherals too.

Ethernet

Ethernet is the dominant standard in the ofﬁ ce

world. The advantages of Ethernet, such as

high data trans mission rates, easy methods of

integration into existing networks, and a wide

range of services and interfaces are also found

in the Beckhoff Ethernet products.

USB

USB has grown into a standard interface for

PC technology. Thanks to its high transmission

rate, ﬂ exible topology through

integrated hubs

and the Beckhoff USB Bus Coupler, this system

can be used as a substitute for a ﬁ eldbus when

distances are small.

Modbus

Modbus is an open, serial communications

protocol based on the master/slave archi-

tecture. Since it is extremely easy to imple-

ment on all kinds of serial interface, it has

gained wide acceptance.

Fipio

FIP complies with the European standard

EN 50170 and receives manufacturer-

independent support from the WorldFIP

organisation. Through periodic and

aperiodic exchange of variables and

messages, the performance of the bus

can be adjusted to the application.

CC-Link

CC-Link (Control & Communication Link)

is an open bus system for communication

between the control and ﬁ eldbus level.

It is predominately used in Asia.

RS232/RS485

The “classic” serial interfaces, RS232 and

RS485, continue in wide use. The Beckhoff

RS485/RS232 I/O modules use a simple,

published serial communication protocol

that is easy to implement.

The ﬁ eldbus toolkit

Beckhoff provides an extensive range of ﬁ eldbus components

for all common I/O and ﬁ eldbus systems. With the bus terminals

in protection class IP 20, and the Fieldbus Box modules in protec-

tion class IP 67, the complete range is available for all relevant

signal types and ﬁ eldbus systems. The Beckhoff Lightbus is the

fast, secure ﬁ eldbus system, specially designed to meet the

needs of automation technology. EtherCAT, the new real-time

Ethernet ﬁ eldbus is a further development of the Lightbus

system. EtherCAT reaches new dimensions in network perfor-

mance. The PC ﬁ eldbus cards have been particularly developed

for fast control and for real-time tasks, and can therefore be

used in a wide range of applications. The I/O range is completed

with the appropriate cord sets, programming and conﬁ guration

tools. The wide choice of I/O components means that the bus

system best suited to the particular application can be chosen:

1 2 ... 22 23 24 25 26 27 28 29 30 31 32 ... 83 84
