Bus modules

As mentioned above, in PCS 7 only active bus modules can be used for redundant
applications with ET 200M. This enables removal and insertion of modules during
operation. To achieve redundant operation, each ET 200M requires two interface
modules IM 153-2 high feature to be mounted on the active bus module.
For the ET 200M standard modules (e.g. DI, DO, AI, AO), further bus modules are
used.

modules, as well as available functionalities, please refer to the manual "
SIMATIC Distributed I/O device ET 200M ".
In practice, an IM 153 redundancy bundle is often ordered for the installation of
a redundant ET 200M station. This consists of two IM 153-2 high feature and one
active bus module IM 153/IM 153.
