In the projection software, standard function blocks are used for the acyclic data exchange between a
PROFINET IO controller and the AC1403/04.
Siemens S7 controllers provide two standard function blocks:

SFB52
RDREC for reading acyclic data

SFB53
WRREC for writing acyclic data
For detailed information regarding SFB52 and SFB53:

Siemens S7 controller!
