6.1.3 Startup of the IM 153-2/153-2 FO
The designation IM 153-2 in this section applies to both the IM 153-2 and the
IM 153-2 FO.
Agreement in the case of Redundancy:
In the case of redundancy, the two inserted IM 153-2 modules operate
independently of one another.
Figure 6-3 shows the startup of the IM 153-2 (a). If you look at the IM 153-2 (b),
the following flow diagram applies with the labels reversed.

Note
If the IM 153-2Bx00 is operated on the bus module BM IM/IM
6ES7 195-7HD00-0XA0, power-up takes approx. 70 seconds (the time taken for
the appropriate operating mode for the bus module to be set up).
If the IM 153-2AA02/-2AB01 has inadvertently been inserted on the bus module
BM IM/IM 6ES7 195-7HD10-0XA0, this IM cannot access the I/O modules. As a
result, the IM cannot be operated in this redundancy system.
