A while ago I configured a ag-send / receive connection without any problem. Today I had to make a new connection in the same project but I have a strange problem. I can send the data from one PLC to the other, but on every update of the send cyclus the received data is in another order. The data is copied but it doesn't end up at the same place. In annex you can find some screenshots. Can somebody help me with my problem

Dear brunovanwynsberghe, I have seen your attach document. Please ensure the other PLCs is not sending to the same DB address. Do take a look at this link and i hope it helps. http://support.automation.siemens.com/WW/view/en/17853532 with regards, how come? |

Hello, You haveconfigured a TCP connection (and not ISO-on-TCP). A native TCP connection could show the behavior you describe when the receiver an the sender are not synchronized. This has to do with the lack of an explicit "end of data stream" in TCP. I suggest to change the connection type to ISO-on-TCP. See more info on TCP connections an theirspecial nature here: http://support.automation.siemens.com/WW/view/en/1235645 |

tosynchronize both Ag_send and Ag_receive. the simplest way is to cycle power on the simatic net card or eithernet card. thats what I did and it worked. |
