IM 153-1 is incorrectly configured - no data
exchange is taking place between the DP mas-
ter and the IM 153-1.
Causes:
• Configured and set PROFIBUS address is
incorrect
• Faults on the bus
• Check the IM 153-1.
• Check the configuration and parameter set-
tings.
• Check the PROFIBUS address on the IM 153-1
and in the STEP 7 project.
• Check the cable length with reference to the
baud rate.
• Check the settings for the terminating resistors.

no connection to the DP master (search baud
rate)
Causes:
• the bus communication via PROFIBUS DP to
the IM 153-1 has been interrupted
Check the bus configuration.
• Check to see if the bus connector is inserted
properly.
• Check whether the bus cable 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 PROFIBUS address and 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).
