SIMATIC ET 200pro 35
Modular, space-saving design
The ET 200pro is compact and up to 16 modules can be com-
bined as required over a length of up to one meter. An
ET 200pro station can be preassembled on the work bench
with narrow module carriers and then fitted to the machine as
a complete unit. Alternatively, the compact module carrier can
also be fixed in place first and the station can be assembled lat-
er. The modules are simply latched into the module carrier and
pushed onto each other. Module carriers are available with 0.5
m, 1 m and 2 m.
The expansion modules are divided in three sections, a bus
module, an electronics module and a connection module:
■ The bus module contains the backplane bus for signals and
supply voltage in build-as-you-go design.
■ The electronics module determines the function and is
easily replaced during normal operation with the equip-
ment live (hot swapping). The station therefore remains
functional in the event of a fault. Coding prevents the
wrong module from being plugged in inadvertently.
■ The connection module complete with independent wir-
ing is plugged on and screwed down with 2 screws. Preas-
sembled connecting cables can be attached quickly and
easily.
8-channel electronics 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 electronics module without the need for additional ac-
cessories such as Y connectors or Y leads. This not only reduces
the wiring but also the costs for accessories and parts invento-
ries.
Failsafe I/O modules are used for inputs and outputs 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 nether total failure of all load groups nor damage
outside the station can occur.
