1.
Perform a hardware configuration for the CPU.

Chapter 5.4
‘Hardware configuration - CPU’ on page 59
2. Configure always as last module a Siemens DP master CP
342-5 (342-5DA02 V5.0). Connect and parameterize it at opera-
tion mode "DP-Master".
3. Connect the slave system "VIP
A_SPEEDbus". After installing
the SPEEDBUS.GSD this may be found in the hardware catalog
at Profibus-DP / Additional field devices / I/O / VIPA /
VIPA_SPEEDBUS.
4. For the slave system set the PROFIBUS address 100.
5. Configure at slot 0 the VIP
A CPU 314-6CF03 of the hardware
catalog from VIPA_SPEEDbus.
6. By double clicking the placed CPU 314-6CF03 the properties
dialog of the CPU may be opened.
The hardware configuration, which is shown here, is
only required, if you want to customize the VIP
A spe-
cific parameters.
5.9.2 VIPA specific parameters
The following parameters may be accessed by means of the proper-
ties dialog of the VIP
A CPU.
5.9.2.1 Function RS485 X3
Using this parameter the RS485 interface may be switched to PtP
communication (point to point) respectively the synchronization
between DP master system and CPU may be set:
Deactivated Deactivates the RS485 interface.
PtP With this operating mode the
PROFIBUS DP master is deacti-
vated and the RS485 interface
acts as an interface for serial
point-to-point communication.
Here data may be exchanged
between two stations by means
of protocols.
PROFIBUS DP async PROFIBUS DP master operation
asynchronous to CPU cycle The
RS485 interface is preset at
default to PROFIBUS DP async.
Here CPU cycle and cycles of
every VIP
A PROFIBUS DP
master run independently.
