    NC/PLC no connection

    Hey!

    We have a problem with the NC/PLC not getting a connection when we restart the machine it says that the system might be corrupt.

    when checking diagnos in the machine it says communication fault repeat the process. If the error is still there do a "NCK" Power on Restet.
    IF the error is still continue the turn off and then on MMC and NCK.

    what is the MMC and NCK?

    First things that came up in a search were:

    MMC = Micro Memory Card

    I know nothing of Siemens so you need to do some research.
