LeonMötter Posted July 2, 2021 Report Share Posted July 2, 2021 I have been having a lot of problems trying to communicate with a new out of the box USC-B5-B1. My first attempt at downloading the program was over USB. When i plug in the USB cable the device is recognizable in the download menu, but when i select it and press the download button the download menu disappears and nothing seems to happen. I have tried rebooting the PC and the PLC and unplugging the USB cable en and plugging it back in with no result. My next train of thought was maybe it has something to do with the PC that i am using, so i swapped PC's and did a brand new installation of Unilogic. The result was exactly the same. The PLC is recognized but i cant seem to do anything with it. My last attempt was to use the Ethernet port. So i plugged that in and switched my PC to a static IP of 192.168.1.10 and put in 192.168.1.4 (which should be the default for this unit). Unilogic could not find the PLC, But when i use ping in the windows command line with address 192.168.1.4 i do get a response. So there seems to be a connection. I also tried switching of the firewall in the PC, but that also does not seem to work. At this point i am running out of ideas, hence this post and hoping someone recognizes this problem. To make sure that all the information is here: PLC: USC-B5-B1 with hardware add-ons: UAC-CB-01RS4_0, UID-0016T_1 and UID-1600_2 Unilogic: version 1.26.90 Quote Link to comment Share on other sites More sharing options...
