Switch on the supply voltage
for the IM 153-2 (a)
IM 153-2Bx00 only:
All LEDs light up for a few
seconds during internal tests
The "ON" and "BF" LEDs come on
IM 153-2
(a) checks
whether it is inserted
on the BM IM/IM
Yes
IM 153-2 (a)
checkswhether
the IM 153-2 (b)
is inserted
Yes
Has the
IM 153-2 (b) already
received configuration data
from the DP master, has it tested
them with the ET 200M configuration,
and is it exchanging data
with the DP master?
Yes
... then the IM 153-2(a)
is passive
The IM 153-2 (a) receives all
the ET 200M data from the
IM 153-2 (b) (if available)
- Actual configuration
- PROFIBUS status
- Queued interrupts
- Time stamp messages
The IM 153-2 (a) receives
configuration data from
the associated DP master
Does the
configuration data
match that
of the IM 153-2 (b)?
Yes
The "BF" LED goes out. The IM 153-2
(a) is ready for data transfer, and is in
standby mode when switchover is
required
