Dear Hamid, Thanks for your comments. I have uploaded my project. Basically took the reference from your earlier suggested link:https://support.automation.siemens.com/WW/llisapi.dllfunc=cslib.csinfo&lang=en&objid=7764609&caller=view Here I could find a sample project of 2 S7 300 plc. In my project I have taken a S7 400 plc whih is trying to read and write into a S7 300 plc using PUT and GET functions. I have configured both plcs using NETPRO in Step7 and generated the S7 communication ID. Whe I try to simulate the project in OB1 I see that the main FB( FB 100) does not get called even after the right inputs. Kindly go through the project and tell me if I have done anything wrong. My main aim is to perofom exchange of DBs b/w 2 plcs on profibus and hence I have not explicitly made S7 300 as slave . Thanks & regards, Falcon

Hello, I am afraid to say you have done all your task on a Wrong Basis .Integral DP port can not be used for an S7 Connection.Please, check the sample project HERE .It is an S7 Connection via MPI as the port can be configured as MPI or DP.Check the configuration again. Many regards,Hamid Hosseini |

Hi Hamid, I just confused a bit. Yes i am originally looking for DB data transfer. I have modified the program and now I have generated MPI based S7 connection. I am uploading the project so please let me know of your feedbacks. Regds, Falcon AttachmentProfibus_Test_V1.zip (128 Downloads) |
