SIMATIC ET 200M is the modular I/O station for the control cabinet with high density-channel applications. Connection to PROFIBUS and PROFINET is achieved using interface modules – optionally for PROFIBUS also using fiber optic cables.
The ET 200M can be used for standard as well as failsafe applications.Up to 12 multi-channel signal modules (e.g. 64 digital inputs) and function modules as well as S7-300 communications processors can be used as I/O modules – the interface to the process. ET 200M supports modules with expanded user data, e.g. HART modules with HART minor variables. In addition to proven connection techniques the ET 200M offers the insulation displacement method Fast Connect for easy wiring.

Area of application  Ask About This Product
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. E-mail Friend

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).
