Control over PROFIBUS DP and PROFINET IO

6.5.1

File Transfer Principle over PROFIBUS DP and PROFINET IO

The following block diagram shows the relevant interfaces of the processing unit for
data transmission over PROFIBUS DP and PROFINET I/O.
Note
Of the "Send" user data interface, bytes 1 to 31 are relevant, of the "Receive" user
data interface, only bytes 1 and 4 are relevant.
If these two user data interfaces are not located in the process image of OB1, you
must use SFC 14 "DPRD_DAT" during the data transfer from the "Send" user data
interface of the processing unit to the DP master to ensure data consistency. In the
opposite direction, SFC 15 "DPWR_DAT" must be used for data transmission from
the DP master to the "Receive" user data interface.
