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.
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.

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).
