PROFIBUS-DP Operating Characteristics
This section describes the basic characteristics of the DHP11B control card connected
to the PROFIBUS-DP system.
5.1
Process data exchange with the DHP11B control card
The DHP11B control card is controlled via the process data channel which is up to 32
I/O words in length. These process data words are mapped in the I/O or peripheral area
of the DHP11B control card, for example when a master PLC is used as the DP master.
As a result, the process data words can be addressed in the usual manner.
Control example
for Simatic S7
The exchange of process data with the DHP11B control card is controlled using Simatic
S7 in accordance with the selected process data configuration either directly using load
and transfer commands or by means of special system functions,
SFC 14 DPRD_DAT
and
SFC15 DPWR_DAT
.
