Posted 15 Sep 2021 (edited) Hi there! Today a CP1E-E10DR-D suddenly stopped working. RUN led was off and I couldn't connect to it via USB getting this error: "Selected port does not exist. Select proper port number from Change PLC dialog and press OK button", and automatic online function didn't work as well(it's not a cable/driver problem since I successfully connected to a CJ2 CPU using same cable and PC). Since I also tried to connect with the CPU outside the control cabinet with no success, I asume there is something wrong at hardware level. My question is, have you ever faced something like this? My plan is to try to revive it somehow (maybe trying to locate any defective component in the PCBs or something). So I was just wondering if you have any advice in order to achieve it. Thanks in advance! Edited 15 Sep 2021 by Robror Share this post Link to post Share on other sites
Posted 15 Sep 2021 What is the status of the error lights on the front of the CPU? Without that info, we would be guessing... Share this post Link to post Share on other sites

Hi, no other led is on, just the green power led. Connection is impossible and sometimes the inputs seem to get stuck on the current state when you press the CPU (happened connecting the USB port, for example). I mean, the machine is simple and has four photoelectric sensors that are continuously changing its state when bottles are passing and sometimes the inputs' leds stay on or off when connecting/disconnecting the USB cable or tapping the CPU itself, despite that bottles are still passing.

Posted 16 Sep 2021 Sounds like a hardware failure... Share this post Link to post Share on other sites
Posted 14 Jun 2022 I have the same problem with the CP1L, only the Power Led lights up and the USB and serial communication is in error "port does not exist" Share this post Link to post Share on other sites
Posted 14 Jun 2022 Thank you very much for the quick answer. I guess there is no solution for that? Share this post Link to post Share on other sites
