PROFIBUS DP is an international, open fieldbus standard, which is
specified in the European Fieldbus Standard EN 50170 Part 2.
PROFIBUS DP is optimized for fast, data transfer at the field level for
time–critical applications.
The fieldbus is used for cyclic and non–cyclic data transfer between a
master and the slaves assigned to this master.
The following communication possibilities are available:
S
Cyclic communications
––> Setpoint, actual value transfer using process data
(PZD communications)
– According to the DP standard functionality
For standard DP operation, a new cycle is started after the old
cycle has been completed.
––> refer to Chapter 5.2
– Clock–cycle synchronous functionality
For clock–cycle synchronous operation a new cycle is started
with the set Tp clock cycle.
––> refer to Chapter 5.2
– Slave–to–slave communications
Fast, distributed data transfer between drives (slaves) is possible
using the "slave–to–slave" communications function without in-
volving the master.
––> refer to Chapter 5.10
S
Non–cyclic communications
––> Access to the drive parameters
– Parameterization using the "SimoCom U" tool
––> refer to Chapter 3.3
– Data transfer using the SIMATIC Operation Panel (SIMATIC OP)
––> refer to Chapter 5.3
– PKW area in the net data structure according to PPOs
––> refer to Chapter 5.6.7
– Data exchange with the master (e.g. SIMATIC S7) and other
control devices, utilizing the DPV1 utility (service) "read data set/
write data set" corresponding to the PROFIdrive Profile
––> refer to Chapter 5.3
S
Engineering
––> Configuring defines the data, which the master transfers
to the "DP slaves" at every bus run–up via the parameterizing
telegram and the configuration telegram.
The system can be configured in the following ways (refer to
Chapter 5.7):
– using the GSD file (SIEM808F.GSD/SI02808F.GSD)
– using the "Slave object manager" (Drive ES)
