Hi,

I'm trying to establish a communication between 317F-2 PN/DP with TIA project and CPU 315F-2 PN/DP with Step7 Project.

In step 7 in Profinet properties->I-Device Tab i create I/O: (pict.1)
1000.........Application.......I-1250..1261......(12 I)
1000.........Application......Q-1250..1255......(6 Q)
1000.........Application.......I-1262..1267.....(6 I)
1000.........Application.......Q-1262..1273.....(12 Q)

and I create and export GSD file

In software I use :
- FB224 (F_RCVDP) with DP_DP_ID=231, timeout=500ms, LADDR=1250
- FB223 (F_SENDDP) with DP_DP_ID=232, timeout=500ms, LADDR=1262

In TIA project I import GSD file, connect to network, parametrize I/O (pict_2):

12O...........1000...........1900-1911....
6I...............1001...........1900-1905...
6O.............1002...........1920-1925....
12I............1003...........1920-1931....

Then in software I parametrize 2 blocks:
- F_RCDVP (1.0, instruction 1.3) with DP_DP_ID=232, timeout=500ms, LADDR=1920
- F_SENDDP (1.0 instruction 1.3) with DP_DP_ID=231, timeout=500ms, LADDR=1900

Connection diagnostic I/O on Step 7 - pict_3
Connection diagnostic I/O on TIA - pict_4 - although every few second (6-7) all retvals goes to 0 for a moment and come back with same values

Any ideas ? I'm out of possible solutions...

EDIT:

Solution is simpler than I thought. In TIA F_Send & F_Recv blocks need to have LADDR in Hex format..
