Distributed I/O Device ET 200M
EWA-4NEB780600602-06
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?
Switch on the supply voltage
for the IM 153-2 (a)
The ”ON” and ”BF” LEDs come on
IM 153-2
(a) checks
whether it is inserted
on the BM IM/IM
No configuration
for ”redundancy”
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
IM 153-2 (a) receives
the configuration data
from the DP master
Does the
configuration data
match that
of the IM 153-2 (b)?
The ”BF” LED goes out. The IM 153-2
(a) is ready for data transfer, and is in
standby mode when switchover is
required
No
No
No
The configuration data is
rejected; error message to
DP master
Does the
configuration
data match the
real configuration?
The ”BF” LED goes out;
the ”ACT” LED comes on.
data transfer is possible
Yes
Yes
Yes
Yes
Match up the configuration
data in the DP master
Startup as in
Figure 6-1 on
Page 6-4
IM 153-2 (a)
checkswhether
the IM 153-2 (b)
is inserted
Time
synchronization
No
Time
synchro-
nization
No
Yes
Data transfer only takes
place with modules that
correspond to the desired
configuration (other modules
or missing modules are
reported by the IM 153-2 in
the module diagnosis)
... then the
IM 153-2(a) is
active
... then the IM 153-2(a)
is passive
IM 153-2Bx00 only:
All LEDs light up for a few
seconds during internal tests
