off There is no voltage at the interface module, or
the interface module has a hardware defect.
Switch on the power supply voltage 24 VDC
on the interface module.

Flashing on The interface module is not configured or is
configured incorrectly. No data exchange is
taking place between the DP master and the
interface module.
Causes:
•
The PROFIBUS address is incorrect.
•
Configuration error
•
Parameter assignment error
•
Check the interface module.
•
Check the configuration and parameter
assignment.
•
Check the PROFIBUS address.
*
on
on Transmission rate detection, illegal
PROFIBUS address, or bottom DIP switch
(PROFIBUS address) not in the OFF position.
Causes:
•
The response monitoring interval has
elapsed.
•
Bus communication to the interface
module via PROFIBUS DP is interrupted.
Set a valid PROFIBUS address (1 to 125) on
the interface module or check the bus
configuration.
•
Check that the bus connector is correctly
inserted.
•
Check whether the connecting cable to the
DP master has been disconnected.
•
Switch the 24 V DC supply voltage on and
off again at the interface module.
The configured structure of the ET 200S does
not match the actual structure of the ET 200S.
Check the structure of the ET 200S for missing
or defective modules or whether an
unconfigured module is inserted.
Check the configuration (using COM
PROFIBUS or STEP 7, for example) and
correct the parameter assignment error.

There is an error in an I/O module, or the
interface module is defective.
Replace the interface module, or contact your
Siemens representative.
