●
Use the rails for "module change during operation" (only these can take the active bus
modules).
●
Close unused slots with the backplane bus cover. Close the last bus module with the bus
module cover. The bus module cover is included with the bus module BM PS/IM or BM
IM/IM. The backplane bus cover has to be ordered.

●
To use the ET 200M in the intrinsically safe area, use the explosion-proof partition -
preferably between the modules in the intrinsically safe area and the modules in the non-
intrinsically safe area.
Greater number of modules with the IM 153-2BAx2 and IM 153-4AA0x
A maximum of 12 modules can be operated with the IM 153-2BAx2 and IM 153-4AA0x
interface module, compared to 8 modules previously.
Restrictions
Use of the high-accuracy time stamp (1 ms accuracy) is only possible with 8 modules. In this
case, a maximum of 8 input modules can be inserted after the IM 153-2BAx2 interface
module in the ET 200M.
