If you perform the update by means of SFCs 112 and 113, then call SFC 112 at the
start of the OB containing the program associated with the PROFInet component
and call SFC 113 at the end of this OB. This procedure is shown using OB 30 as

Note
Note on multifunction components (several PROFInet interface DBs on one
device):
With multifunction components you can update all interface DBs with an SFC job
(DBNO=0). This is similar to the update at the cycle control point, only triggered by
SFC. If an error occurs during the update of an interface DB, the other interface DB
updates will be continued. A negative RET_VAL refers to one of the updated
interface DBs.
Updating the DP Interconnections
The DP interconnections are updated by either the operating system or by means
of SFC 114, depending on how you configured the PROFInet components in the
SIMATIC Manager.
