4.4 Settings at the PROFIBUS–DP master
Open "OB1" (object folder).
In the Program Editor, enter the "CALL SFC 14" command and
press the RETURN key. The SCF 14 is displayed with its input and
output parameters.
Initialize the input and output parameters. Now, call SFC 15 and
initialize the parameters, accordingly.
When the two SFCs are called–up, the associated block shells for
these standard functions are automatically copied into the block ob-
ject folder from the STEP 7 standard library.
In order to be able to simply check the data transfer in the applica-
tion example, allocate the data, as shown in the example, to an ap-
propriate data block.
Now save OB 1 with save and close the window of the program edi-
tor for the OB 1.
Now create DB 40. Using the task bar, change from Windows to the
SIMATIC Manager and select the blocks object folder. The block
objects, system data, OB 1, DB 40, SFC 14 and SCF 15 are in this
object folder.
Transfer these with "download all blocks" into the CPU 315–2DP.
After the transfer has been completed, the CPU 315–2DP must be
switched back to RUN.
If the motor is connected, the LED display elements for the DP in-
terface are dark. The CPU must be in the RUN condition.
