Hello, I have a problem with FB block for sending UDP packets. It is possible for the SIMATIC S7-1200 to send a UDP packet as a broadcast packet? I used TUSEND, but I not posted nothing. You can do some simple example? Here is my test program. But I do not know why it does not work. Thank you ... AttachmentTEST.zip (741 Downloads) |

Hello... Much as I can understand... When I want to send a UDP or TCP packet, you must use the first function - TCON? And then, for udp - TUSEND and tcp - TESEND? |

Hello, This is not true. If you do upgrade Simatic S7-1200 to version 2.x, so it supports. |

There is a FAQ with T_SEND_C With this FB, you do not need TCON, TDISCON http://support.automation.siemens.com/WW/view/en/67196808 Have you try to copy the status-value of TCON in another variable? What is the state? |
