SIMATIC ET 200pro is a modular I/O system with high IP65/66/67 

protection suitable for use at machine level outside the control 

cabinet. As a result of the innovative design, the ET 200pro has 

a relatively small size and can be flexibly adapted to the require-

ments of the respective automation task with regard to the con-

nection system and I/Os. Summary of the most important fea-

tures of the SIMATIC ET 200pro:
• Distributed I/O system with IP65/67 protection for use without 

a control cabinet at machine level

• Small, multi-functional complete solution: analog and digital 

I/O modules as well as safety-related digital I/O modules

• Communication over PROFIBUS DP, transmission rate up to 

12 Mbit/s

• Mixed design of fail-safe and standard modules possible in 

the same station

• Free selection of connection system: direct, ECOFAST or 

M12 7/8"

• Power module for simple implementation of load groups
• Hot swapping of modules
• Simple assembly and independent wiring
• Comprehensive diagnostics: exact to the module or channel

■

The architecture of the ET 200pro is based on the proven sepa-

ration of modules from the bus/power supply connection system. 

This permits the T functionality for bus and 24 V DC power sup-

ply for the interface module, and prewiring of sensor/actuator 

connections for the electronics modules (independent wiring). 

When servicing, the independent wiring permits hot swapping of 

an electronics module without having to switch off the remaining 

station. This can continue without interruption during the re-

placement. When replacing an electronics module, the com-

plete I/O wiring remains on the connection module, and need be 

neither labeled nor removed.
Up to 16 electronics modules can be arranged in any order be-

tween the interface module (left) and the terminating module 

(right limit).

The ET 200pro modules are usually designed in two or three 

parts. Interface and power modules as well as digital and analog 

electronics modules comprise:
• Bus module as mechanical and electrical connection element 

of the individual ET 200pro modules (they form the backplane 

bus of the system)

• Electronics or interface module
• Connection module
The ET 200pro modules are fitted when delivered on the associ-

ated bus module.
An ET 200pro station comprises:
• Module support
• Interface module for PROFIBUS DP
• Connection module for the PROFIBUS DP interface module 

- CM IM DP direct with up to 6 M20 cable glands

- CM IM DP ECOFAST Cu

- CM IM DP M12 7/8"

• Max. 16 electronics modules with associated connection 

modules which may be assembled up to a station width of 1 m

• Terminating module (included in scope of delivery of interface 

module)

The following expansion modules are available:
• Digital electronics modules
• Analog electronics modules
• Safety-related electronics modules
• I/O connection modules 

- CM IO 4 x M12 for digital or analog electronics modules

- CM IO 8 x M12 for digital electronics modules

- CM IO 12 x M12 for 4/8 F-DI/4 F-DO

- CM IO 16 x M12 for 8/16 F-DI

• Power module electronics PM-E
• Connection modules for power module 

- CM PM-E direct with up to 2 M20 cable glands

- CM PM-E ECOFAST Cu

- CM PM-E 7/8"
