For configuring the drive within the framework of the NC commissioning, please refer to
Subsection
"Drive configuration" (Page 389).
② DP master
The DP master periodically transfers the isochronous process data to/from DP slaves S120
based on the configuration set in SIMATIC STEP 7 HW Config:
PROFIBUS address: 10
Object I/O address Message frame
1 4100 102
2 4140 102
3 4180 102
Transferring the process data to DP slave S120
The process data of the machine axes are read by the DP master from the configured I/O
addresses and transferred to the DP slave S120 in the PROFIBUS message frame
according to the configured object sequence.
Reading the process data from DP slave S120
The process data of the machine axes are read by the DP master in the configured object
sequence from the PROFIBUS message frame and transferred to the corresponding I/O
addresses.
③ DP slave S120
DP slave S120 interprets the PROFIBUS message frames received from the DP master
based on the STARTER configuration:
PROFIBUS address: 10
Object Antriebsobjekt No. Frame type
1 Drive_1 3 SIEMENS message frame 102
2 Drive_2 4 SIEMENS message frame 102
3 Drive_3 5 SIEMENS message frame 102
4 Infeed 2 Free message frame configuration with
BICO
5 Control Unit 1 Free message frame configuration with
