Area of application

The ET 200M is particularly suitable for user-specific and complex automation tasks. Applicable Ex analog input or output modules with HART optimize the ET 200M for use in process engineering. Applications that require a higher grade of availability can be realized in combination with redundant systems like S7-400H or S7-400F/FH.

Benefits

• High density channel design (up to 64 channels per module)

• Reduced wiring efforts

• High plant availability
   - Configuration in RUN
   - Hot Swapping of modules
   - Redundant design

• Modular design

• Use of S7-300 modules

• Safety functions integrated

• Integrated diagnostic function channel by channel

• Certified for Ex-zone 2

Design and functions

The modular I/O system ET 200M comprises an Interface Module (2 IM in case of redundant design) and up to 12 I/O modules. There are no slot rules. Various types of I/O modules can be plugged in depending on the quantity framework of the master module.

The SIMATIC S7-300's simple construction using bus connectors makes the ET 200M flexible and service friendly:

The bus modules are swung onto the DIN rail, butted side to side and secured with lateral plug-in connectors. The modules can then be swung onto the bus modules and screwed into position establishing contact with the bus module connector. The connectors of unoccupied slots must be protected with backplane bus covers. A bus module cover is inserted into the side of the last bus module. The backplane bus has been integrated into the modules. The active bus modules permit changing of modules during operation (Hot Swapping). When the ET 200M is connected to PROFIBUS on an S7-400, the controller can be configured during normal operation (Configuration in RUN - CiR).
