The Fieldbus Box

A number of considerations led, years ago, to the introduction

of the ﬁ eldbus systems: The ﬁ rst target was a reduction in the

quantity of wiring. Simpliﬁ ed system diagnostics, enabled by

intelligent ﬁ eld devices that could send detailed information

about malfunctions and errors quickly to the controller, came

later. Finally the ﬁ eld devices were given controller functionality

for distributed data pre-processing and for simple control tasks.

Fieldbus Box

ﬁ eldbus user organisations, and can be

combined with Beckhoff Bus Terminals and

with devices from third-party manufacturers.

Modular

Extension modules allow the Coupler Box

modules to be inexpensively extended.

Quickly wired

The wiring of the ﬁ eldbus and of signals

is signiﬁ cantly simpliﬁ ed through the use

of pre-assembled cables. Wiring errors are

minimised, and the system setup is ﬁ nished

quickly.

Flexible

In addition to the pre-assembled cables,

ﬁ eld wireable connectors and cables are

also available for maximum ﬂ exibility.

Economical

Combined I/O modules and ﬁ ne signal

granularity lead to low system costs – you

only have to buy what you really need.

Complete

The wide variety of signal types allows the

connection of almost any kind of sensor. The

communication modules enable decentral-

ised connection of, e.g., label printers, iden-

tiﬁ cation systems or special equipment. The

The Beckhoff Fieldbus Box system

is the culmination of the ﬁ eldbus

concept:

Robust

Robust construction allows ﬁ eldbus

modules to be ﬁ tted directly to machines.

Control cabinets and terminal boxes are

now no longer required.

Sealed

The modules meet the protection class

IP 65, IP 66 or IP 67, are fully casted and

thus ideally prepared for use in wet, dirty

and dusty working environments.

Small

The modules are extremely small, and are

thus suitable for use in applications where

there is very little space available. The low

weight of the Fieldbus Box modules makes

them useful in applications where the I/O

interface is in motion (e.g. on a robot arm).

Open

All the most important ﬁ eldbus systems are

supported. This substantially frees electrical

design from the particular bus system in use.

Fast, ﬂ exible reactions to customers‘ require-

ments are possible. The Fieldbus Box modules

are, of course, certiﬁ ed by the respective

Fieldbus Box range also includes encoder

interfaces for displacement and angle mea-

surement.

Fitting

Sensors and actuators are connected through

8 mm diameter snap type or through

screw

type connectors (M8 or M12). The snap type

connectors lock in place positively, forming

a vibration proof connection, while the screw

type connectors offer the advantage of high

resistance to being pulled out.

Compatible

The Fieldbus Box devices behave very much

like the Beckhoff Bus Terminals – this means

that the ideal distributed peripheral device

can be used, whatever the particular appli-

cation.

Intelligent

Even the standard modules are intelligent

ﬁ eldbus devices – with self-diagnosis and

versatile functions. The Fieldbus Box is fur-

thermore available as a small local control-

ler – the PLC Box. Programmable in all ﬁ ve

languages in accordance with IEC 61131-3,

with ﬂ oating point arithmetic and with

sufﬁ cient performance and memory for

the majority of decentralised control and

regulation tasks.
