SIMATIC ET 200M
The SIMATIC ET 200M is a modular I/O system with IP20 degree of protection, which is especially well-suited for
user-specific and complex automation tasks.
Design
The SIMATIC ET 200M comprises one IM 153 Interface Module, up to 12 I/O modules of the S7-300 automation
system and, where applicable, a power supply.
There are no slot rules for the I/O modules. They can be combined in any way.
The simple design with bus connectors of the SIMATIC S7-300 makes the ET 200M flexible and service-friendly.
Components
Interface Module
:
The ET 200M is connected to PROFINET or PROFIBUS DP via an IM 153 Interface Module. A fiber-optic
connection to PROFIBUS DP is possible via an additional OLM (Optical Link Module) or an OBT (Optical Bus
Terminal).
I/O modules
:
Depending on the quantity structure of the Interface Module (IM), various quantities and types of I/O modules
(signal, communication and function modules of the SIMATIC S7-300) can be connected.
Power supply
:
Single-phase power supplies with 2 A, 5 A and 10 A are available for the ET 200M as special version.
Configuration, parameter assignment and diagnostics
The ET 200M is configured and parameterized via STEP 7 or the TIA Portal.
The ET 200M is checked for flawless functioning via diagnostic functions.
The ET 200M diagnoses module faults, short-circuits (outputs), bus faults, i.e. erroneous data transmission, and
the 24 V DC load voltage supply.
