Hello, For global data communication , there are some limitations witin the real PLCs as S7 400H does not support that.For S7 300 you have options of using (SFC 65,66,67,68) or GD Table.I think both are not possible with PLCSIM.You can try a configuration between two S7 400 and network in MPI (type S7 connection if possible) .Use functions SFB14/SFB15 for example and update here .

As Ayman said, Global Data communication is not possible with PLCSIM.But as I mentioned before, S7 connection via MPI can be done.See the result in the attachmnet and the source project that I will upload soon. //codes in OB35(100ms) [code] // L B#16#FF // T MB 0 AN M 200.0 = M 200.0 CALL "PUT" , DB15 REQ :=M200.0 ID :=W#16#1 DONE := ERROR := STATUS:= ADDR_1:=P#M 0.0 BYTE 1 ADDR_2:= ADDR_3:= ADDR_4:= SD_1 :=P#M 0.0 BYTE 1 SD_2 := SD_3 := SD_4 :=[/code] Best regards Hamid Hosseini AttachmentMPI_PART1.zip (164 Downloads) |
