    Hi everyone,
    I've a trouble with my plc
    Now when I'm trying to etablish a connection with it, I've the windows: No device is responding to the scan request
    But when I scan the network I'm able to see it
    I'm able to ping it and I can acces to his memory by: ftp://IP_Adress
    Yesterday I was able to etablish a connection with it but today (nothing has changed) It's impossible
    The plc is currently running

    So if someone has an idea to what to do

    Many thanks in advance

    Dom

    Hi,
    which plc is this...?
    maybe the bootproject is corrupt and lead to an crash on the startup of the runtime

    Are you on the same network segment? You can get problems when you are on a switched network. For example the default broadcast addresses for network variables don't work in ours.
    If you haven't tried that then try it without a switch.

    I have a similar problem with c300 from Lenze. But the problem was an bug that i made in the code.

    The problem was that we write our program on c300, and everytime it srarts has rhe same problem.

    Watching log and erasing our program from cfcard solves the problem.

    Responds a ping but not able to connect.
