Hi, Kris Thank your very much for keepingtry to solve my problem. I attached the screenshot with the piece of code, but this is the test program in which I try to see whatsoever from my ehernet port, so it is only constant call of FC6 in OB1 or OB35 (I tried both). Frankly speaking this is the first time I use this function, so maybe there is some tricks in using it. After reading help and manual all seems rather straightforward. If I'm mistaken please correct me. By the way, Kris. I got the reply from Siemens support regarding this problem. They say that broadcasting reading is blocked intentionallyso there is no way out. This is what I was afraid of from the very beginning. I was given this link: “S7-CPs for Industrial Ethernet Configuring and Commissioning Release 05/2008 C79000−G8976−C182−09 Manual Part A − General Application” http://support.automation.siemens.com/WW/view/en/31526060 Chapter 5.7.3 UDP with broadcast and multicast Paragraph: Why does an S7 CP prevent reception on broadcast connections? |
