The embedding of the CPU 315-4PN23 happens by means of a virtual PROFIBUS
master system with the following approach:
1.
Perform a hardware configuration for the CPU.
tion - CPU' page 40
2.
Configure always as last module a Siemens DP master CP 342-5 (342-5DA02
V5.0). Connect and parametrize it at operation mode "DP-Master".
3.
Connect the slave system "VIPA_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 VIPA CPU 315-4PN23 of the hardware catalog from
VIPA_SPEEDbus.
6.
By double clicking the placed CPU 315-4PN23 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 VIPA specific parameters.
The following parameters may be accessed by means of the properties dialog of the
VIPA-CPU.
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
PtP
PROFIBUS DP async
PROFIBUS DP syncIn
PROFIBUS DP syncOut
Setting VIPA specific CPU parameters > VIPA specific parameters
Deactivates the RS485 interface.
With this operating mode the PROFIBUS
DP master is deactivated 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 master operation asyn-
chronous to CPU cycle The RS485 inter-
face is preset at default to PROFIBUS DP
async. Here CPU cycle and cycles of
every Yaskawa PROFIBUS DP master run
independently.
The CPU is waiting for DP master input
data.
The DP master system is waiting for CPU
output data.
