Status/controlling, programming via PROFIBUS-DP
You can program the CPU or execute the PD functions listed in Chap. 4.4 via the
DP master interface.
Note
The use of status and control via the DP master interface extends the DP cycle.
Equidistance
As of STEP 7 V5.2, with the IM 151-7 CPU and DP master module, you can
parameterize bus cycles of the same length (equidistant) for PROFIBUS subnets.
You will find a detailed description of the functions in the Online Help for STEP 7.
PROFIBUS address of the DP master
The permitted PROFIBUS-DP addresses are 1 to 125.
Each address can be allocated only once on the PROFIBUS-DP.
