IM 153-2 is incorrectly configured - no
data exchange is taking place between
the DP master and the IM 153-2.
Causes:
•
PROFIBUS address is incorrect
•
Faults on the bus.
•
Check the IM 153-2.
•
Check the configuration and
parameter settings.
•
Check the PROFIBUS address on
the IM 153-2 and in the STEP 7
project.
•
Check the cable length with
reference to the baud rate.
•
Check the settings for the
terminating resistors.
*

on
no connection to the DP master (search
baud rate)
Causes:
•
the bus communication via PROFIBUS
DP to the IM 153-2 has been
interrupted
Check the bus configuration.
•
Check to see if the bus connector /
FOC is inserted properly.
•
Check whether the bus cable / FOC
to the DP master is defective.
•
Switch off and on the on / off power
switch for the 24 V DC on the power
supply module.

The configured structure of the ET 200M
doesn´t tally with the actual structure of
the ET 200M
Check the configuration of the ET 200M
to see if a module is missing, faulty or if
there is a non-configured module.
Check the configuration (e.g. with
COM PROFIBUS
or
STEP 7
).

inadmissible PROFIBUS address
Is the SF LED of an SM / FM also lit?
•
If so: Error or diagnosis in an S7 300
module
•
If not: IM 153-2 is faulty.
On the IM 153-2 set a valid PROFIBUS
address (1 to 125)
Check the SM / FM with the
diagnostics. Replace the S7-300
module or the IM 153-2 or contact your
Siemens representative.

The IM 153-2 is exchanging data with the
DP master and the I/O modules of the ET
200M.
In redundant mode this IM 153-2 is the
active one of the ET 200M.

There is voltage on the IM 153-2.
In redundant mode this IM 153-2 is the
passive one, i.e. no data exchange with
the I/O modules.

In redundant mode, this IM 153-2 is the
passive, and is not ready for a fault-free
changeover (e.g. associated CPU in
STOP mode).
Switch the H system to redundant
mode.
