Guest BobH Posted February 12, 2019 Report Share Posted February 12, 2019 Hello, I am a student , also in PLC programming. After I got used to Unilogics I got a internship order. I need some help with TCP data Rx/Tx, especially with the programming ladder blocks. My program is now so far working that I can see that my PLC and Hercules ( on laptop ) are connected but then i can't get it working. First up i want to try to make a very simple light lit up when i received data. So I had it configured like in the image. The day before I programmed it like that I was able to see the quantity of byte's that was received in box D. But today with de configuring in the image that isn't even working. Questions i especially have : - The block does need to know when (at how much byte's) the box E (remote IP) it must power up, right? - I really want to know what the functions are from the I/O's of the TCP SERVER Rx/Tx data block? Can someone please explain it in more simple language? thanks for help in advance Quote Link to comment Share on other sites More sharing options...
