Installation in an Intrinsically Safe Area
If you use the ET 200M in intrinsically safe areas, you must insert a DM 370
dummy module between the IM 153-x and the modules in the intrinsically safe
area. This is the only way to adhere to the required thread length (see also the
Intrinsically Safe I/O Modules) Reference Manual.
4.1.4 Rules for Configuring the ”Module Change During Operation”
and ”Redundancy” Functions
Rules
The following rules apply in addition to those listed in Section 4.1.3:
You must insert the IM 153-x and all SMs/FMs/CPs on active bus modules.
For redundancy with IM 153-2 you must insert the interface module on the
active bus module BM IM/IM in the following way:
IM 153-2
on bus module 6ES7 195-
6ES7 153-
7HD00-0XA0 7HD10-0XA0
2AA02-0XB0
2AB01-0XB0
Yes No
2BA00-0XB0
2BB00-0XB0
Yes
The IM 153-2Bx00 then runs in
compatible mode with the
functionality of IM 153-2AA02/
-2AB01.
Yes
The new functions of the
IM 153-2Bx00 are only provided
with this bus module.
Note
The active bus module 6ES7 195-7HD10-0XA0 has two yellow markings to aid
identification. These markings indicate that only IM 153-2Bx00 modules should be
inserted on this bus module.
