Application

SIMATIC ET 200pro is the new modular I/O system with high degree of protection IP65/66/67 for local, cabinetless applications. ET 200pro distinguishes itself through a small frame size and an innovative installation concept. ET 200pro can be optimized and very flexibly adapted to the requirements of the corresponding automation task with respect to the connection method, required I/Os and fieldbus connection. New features such as the integrated PROFIsafe safety technology, the PROFINET interface and the ability to hotswap modules permit it to be used for a wide range of applications.

With the integrated motor starters, conveyor applications can be implemented optimally, or drives of up to 5.5 kW can be controlled without control cabinet.

Design

The tried and tested separation of module and bus/power connection technology, which has already been used for the ET 200eco, is now also used for the digital and analog expansion modules of the ET 200pro. For the interface module this allows use of the T-functionality for the bus and 24 V power supply, and for the expansion modules it permits pre-wiring of sensor/actuator connections. This permanent wiring allows exactly one electronics module to be hot-swapped in the event of a fault without having to switch off the whole station. It can continue to operate fault-free while the module is being replaced. This ensures very high plant availability. When an electronics component is replaced, the whole I/O wiring can remain on the connecting module and does not have to be marked or removed.

Modules

The modules of the ET 200pro usually have two or three components. Interface and power modules as well as digital and analog expansion modules comprise:

  • A bus connector which constitutes the backplane bus of the system
  • An electronics module or interface module
  • A connection module

A backplane bus module is required for operation of motor starters.

A station is constructed from:

  • A rack
  • An interface module for PROFIBUS DP
  • A connection module for the interface module for PROFIBUS DP
    • CM IM DP direct with up to 6 M20 screwed cable glands
    • CM IM DP ECOFAST Cu
    • CM IM DP M12 7/8″

Or optionally

  • One interface module each for PROFINET IO
  • A connection module for the PROFINET IO interface module:
    • CM IM PN M12 7/8″ S
    • CM IM PN M12 7/8″
    • CM IM PN 2 x RJ45
    • CM IM PN 2 x SCRJ FO

Or optionally

  • one CPU or one F-CPU
  • Max. 16 expansion modules that can be mounted in stations up to 1 m in width

Expansion modules

The following expansion modules are available:

  • Digital I/Os
  • Analog inputs
  • Analog outputs
  • IO connection modules
    • CM IO 8 x M8 for digital electronic modules
    • CM IO 4 x M12 inverse for digital electronic modules
    • CM IO 4x M12 for digital or analog electronic modules
    • CM IO 4 x M12 P for digital electronic modules
    • CM IO 8x M12 for digital electronic modules
    • CM IO 8x M12 P for digital electronic modules
    • CM IO 8 x M12 D for digital electronic modules
    • CM IO 2 x M12 for digital electronic modules
    • CM IO 1 x M23 for digital electronic modules
  • Power module electronics
  • Connection modules for power modules
    • CM PM-E PP (Push Pull)
    • CM PM-E directly with up to 2 M20 screwed cable glands
    • CM PM-E ECOFAST Cu
    • CM PM-E 7/8”
  • Fail-safe electronic modules
  • Motor starters
  • Fail-safe motor starters
  • Frequency converters

  • Pneumatic interface modules
  • IO-Link master

Racks

Two different racks are available for mounting the ET 200pro:

  • Narrow rack
    The narrow rack supports complete pre-assembly on the workbench by means of two mounting flanges outside of the ET 200pro station.

  • Compact rack
    When the compact rack is used, the small footprint of the ET 200pro system can be used to best advantage.

Function

The SIMATIC ET 200pro is easily configured with STEP 7. A GSD file is available for interfacing with systems of other manufacturers.
