3.5 Configuring the mechanical structure
ET 200M

3.5.4 Arrangement of the modules for the function "Change During Operation" and / or
"Redundancy"
Arrangement rules
The following rules apply to the location of the modules in an ET 200M:
● An ET 200M can only be installed on one mounting rack (rail), because coupling to other
mounting racks via interface modules is not permissible.
● A maximum of 8 signal modules, function modules or communication processors may be
inserted to the right alongside the IM 153-x.
● The IM 153-x and all the SM / FM / CP must be connected to active bus modules.
With the respective configuration, you can compatibly operate the combinations of interface
modules IM 153-2 specified in the following table on active bus modules BM IM/IM.
Table 3- 3 Compatible versions of the IM 153-2 interface module
If the redundant IM 153-2 are
configured as ...
... and the interface modules are
connected to the active bus
module 6ES7195-…,
then the following IM 153-2 can
be operated compatibly:
7HD00-0XA0 IM 153-2AA02
IM 153-2BA00
IM 153-2BAx1
IM 153-2AA02
7HD10-0XA0 IM 153-2BA00
IM 153-2BAx1
IM 153-2BA00 7HD10-0XA0 IM 153-2BA00
IM 153-2BAx1
7HD10-0XA0 IM 153-2BAx1 IM 153-2BA01
7HD80-0XA0 IM 153-2BAx1
IM 153-2BA81 7HD80-0XA0 IM 153-2BA81
7HD00-0XA0 IM 153-2AB01
IM 153-2BB00
IM 153-2AB01
7HD10-0XA0 IM 153-2BB00
IM 153-2BB00 7HD10-0XA0 IM 153-2BB00
Note
The active bus modules 6ES7195-7HD10-0XA0 and 6ES7195-7HD80-0XA0 are given two
yellow markings for easier identification. These marks indicate that only IM 153-2Bx00 or
IM 153-2Bxx1 can be connected to these bus modules.
