Data sets
Reading/writing data sets with STEP 7
You can access the data sets of the motor starter from the user program.
● Writing data sets:
S7-DPV1 master: by calling SFB 53 "WR_REC" or SFC 58
S7 master: by calling SFC 58
● Reading data sets:
S7-DPV1 master: by calling SFB 52 "RD_REC" or SFC 59
S7 master: by calling SFC 59
SFC 58 and 59 cannot be used with PROFINET. The blocks

Blocks SFB 52 or 53 are to be used for PROFINET. These also function with PROFIBUS.
