Read and write data records
To read and write data records, use the following SFCs or SFBs:
• PROFIBUS:
– Read data record: SFC 59 "RD_REC"
– Write data record: SFC 58 "WR_REC"
• PROFIBUS/PROFINET:
– Read data record: SFB 52 "RDREC"
– Write data record: SFB 53 "WRREC"
For more detailed information on SFCs, refer to the "System Software for S7-300/400 (

Con󹪝guration with GSD 󹪝le
There are di󹪜erent con󹪝gurations for the analog electronic modules 4 AI I 2WIRE HART and 4 AI
I 4WIRE HART that you can select via the following entries in the hardware catalog of the
con󹪝guration software:
• Con󹪝guration "4 AI I 2WIRE HART" and "4 AI I 4WIRE HART"
The analog values are shown in S7 format.
• Con󹪝gurations "4 AI I 4W+x" and "4 AI I 4W+x":
The analog values are shown in S7 format. In addition, up to 4 IEEE variables (primary or non-
primary variable) are available in IEEE 754 format. You select the number of IEEE variables (1
to 4) via the con󹪝guration:
– ...4W+1
– ...4W+2
– ...4W+3
– ...4W+4
