3.2 Diagnostic messages of the electronic modules
Actions following a diagnostic message in DPV0 mode
The error is entered in the diagnostics frame in the channel-specific diagnostics:
● The SF LED on the interface module lights up.
● Several diagnostic messages can be output simultaneously.
14
Cause
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.
The configured structure of the ET 200S does
not match the actual structure of the ET 200S.
There is an error in an I/O module, or the
interface module is defective.
Data exchange is taking place between the DP
master and the ET 200S.
The set configuration and actual configuration
of the ET 200S match.
Remedy
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.
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.
Replace the interface module, or contact your
Siemens representative.
