SIMATIC ET 200pro 43

Modular, space-saving design

The ET 200pro has a modular and extremely compact design.

Up to 16 modules can be combined in any way over a length

up to one meter. An ET 200pro station can be preassembled

on the work bench with narrow module carriers and then fit-

ted to the machine as a complete unit. Alternatively, the com-

pact module carrier can also be fixed in place first and the sta-

tion can be assembled later. The modules are simply latched

into the module carrier and pushed onto each other. Module

carriers are available in lengths of 0.5 m, 1 m and 2 m.

The expansion modules are divided into bus module, electron-

ic module and connection module:

•The bus module contains the backplane bus for signals

and supply voltage in build-as-you-go design.

•The electronic module determines the function and is eas-

ily replaced during normal operation with the equipment

live (hot swapping). The station therefore remains func-

tional in the event of a fault. Coding prevents the wrong

module from being plugged in inadvertently.

•The connection module with permanent wiring is plugged

on and screwed down with 2 screws. Pre-assembled con-

necting cables can be attached quickly and easily.

8-channel electronic modules can be combined with the 8 x

M12 or 4 x M12 connection modules. This gives you the

choice of single or dual assignment of the M12 sockets.

A wide variety of different sensors and actuators can therefore

be connected to the electronic module without the

need for additional accessories such as Y connectors or Y

leads. This not only reduces the wiring but also the costs for

accessories and parts inventories. Wiring with connection

modules 8xM8, 2xM12 and 1xM23 is also possible.

Failsafe I/O modules permit the integration in safety-related

plants with SIMATIC Safety Integrated.

Selective formation of load groups

Power modules allow load groups to be built up as required

by supplementary supply from the load power supply. In this

case, the same connection techniques (direct connection;

M12, 7/8"; ECOFAST) are available as for the power supply of

the complete station. More than one load segment can be in-

tegrated into a single station.

In the interface and in each power module, built-in fuses en-

sure that neither total failure of all load groups, nor damage

beyond the station can occur.
