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.
• Parameter assignment 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 mod-
ule via PROFIBUS DP is interrupted.
Set a valid PROFIBUS address (1 to 125) on
the interface module or check the bus configu-
ration.
• 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.
On * On 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 unconfig-
ured module is inserted.
Check the configuration (using COM
PROFIBUS or STEP 7, for example) and cor-
rect the parameter assignment error.
There is an error in an I/O module, or the inter-
face module is defective.
Replace the interface module, or contact your
Siemens representative.
Off Off On Data exchange is taking place b
etween the DP
master and the ET 200S.
The set configuration and actual configuration
of the ET 200S match.
