WAGO I/O-SYSTEM 750 Manual page 93

* The addresses stated in the table correspond to the process data allocation given in the
configuration.
If the PROFIBUS master is a Siemens S7 SPS, the data is consistently read
and written with the system functions SFC14 and SFC15.
To map the input data EW20 through EW30 to the flag area MW100 through
MW110, the functions are accessed as follows:
CALL SFC 14
LADDR := W#16#14 (read from input address EW20)
RECORD := P#M100.0 BYTE 12 (write 12 bytes beginning with MW100)
RET_VAL := MW112 (write error messages after MW112)
To map the output data AW10 through AW20 to the flag area MW114
through MW124, the functions are accessed as follows:
