Poljachina Posted June 29, 2021 Report Share Posted June 29, 2021 Hello all. I have two Sambas at the workshop for an upcoming project. Up until yesterday everything worked fine. I was able to download the PLC and HMI changes that I made without problems. But yesterday something happened to one of the PLC's. I can't connect to it any more, the connection to the other works like before. The PLC works, but I cant download the changes that I need to make... If I check in the info mode under the serial tab I just see that 1 byte is being sent and 1 received when I try to connect with Visilogic. Any ideas what to do to get the PLC working again?
