I just ran into the same problem. I have a LOGO 0BA7 that communicates to a Logo 8.3 but suddenly the 0BA7 stopped communicating. I can communicate with the other one, however not anymore with the 0BA7. FW V01.03.36 LED RX/TX Steady On Orange LED LINK Steady On Green Even without cable, the link stays green. The Logo does not respond anymore to pinging from the computer LOGO can run the program by using the SD card. Is there anything I can do from here? Is this a component in the network section of the PCB that can be replaced, or is it the µcontroller that is broken? Thanks Davy ------------------------------------------------------------------------------------------ |

I've never seen a logo break if you just plug in a network cable. The only thing I can think of would be to use PoE, which the Logo cannot do. Buying one on the used market is a dubious gamble. One does not know the previous life and the handling of this device. And for a price of €170 you get a new device. You can upgrade your LSC to the latest version for free. As far as the Ethernet chip is concerned, some standard Broadcom chip will probably be installed. This will definitely not be part of the CPU. But you would have to open your logo and have a look for yourself. Of course, Siemens does not disclose such technical details. Just found the CPU datasheet.The Ethernet controller is part of the CPU.Unfortunately, you can then bury any hope of repair. greeting Ella_68 (translated with Google) |
