9.1.4 PROFIBUS DP communication
9.1.4.1 PROFIBUS DP configuring
The ASM 452 is integrated into the hardware configuration by means of a GSD file. The
ASM can then be configured using the HW Config of SIMATIC Manager or another
PROFIBUS DP tool.
A GSD file is provided for ASM 452 on the "MOBY software" CD.
9.1.4.2 Operating mode of the ASM 452
The approved operating modes of ASM 452 are described in the GSD file. It is set using the
hardware configuration tool (e.g. STEP 7 HW Config).
9.1.4.3 PROFIBUS DP diagnostics
The following table lists possible error indications with their meanings and provides
remedies.

 ASM 452 is in start-up mode.
-
 Communication to the DP master
is down.
 ASM 452 not detecting a baud
rate.
 Check the PROFIBUS DP
connection.
 Check the DP master.

 Bus interruption
 DP master is out of service
 Check all cables on your
PROFIBUS DP network.
 Check whether the connector
plugs for PROFIBUS DP are
securely plugged into the
ASM 452.

 The configuration data sent to
the ASM 452 by the DP master
do not match the configuration of
the ASM 452.
 Check the configuration of
the ASM 452 (input/output,
PROFIBUS DP address).
 Correct GSD file being used?

 ASM 452 has detected the baud
rate, but is not being addressed
by the DP Master.
 ASM 452 has not been
configured.
 Check the PROFIBUS DP
address set on the ASM 452
or in the configuration
software.
 Check the configuration of
the ASM 452 (station type).
On flashes
 There is a hardware defect in the
ASM 452.
 Replace the ASM 452.
