    Exclamation Fanuc 0i Mate-MB Write Protected for Parameter Write

    Please help...!!

    I am using AMS MCV-400 VMC . Now For simplicity and 3D modelling I decided to connect with PC . I have a ready RS232C Cable and PC . But the MAchine not responding.
    The Parameter number 100 , 101 are unable to edit since it is " WRITE-PROTECTED". When tried to change the " PARAMETER WRITE : 0 " to " PARAMETER WRITE : 1 " It cannot changed . It remains at 0 . and shows alarm message again as Write-Protected .
    I have VMC machine with RS232C port
    Fanuc i0 Mate -MB

    In MDI, push your offset key several times untill you see the Handy page. Parameter Write Enable is there, turn it to a 1. Now you can edit parameters. Be sure to write down the original values before making any edits, and be sure to go back to handy and set P W E back to 0. It is best to make sure you have an backup before changing anything just in case.

    PWE Write Protect Bit
    Parameter 3292 bit 7
    PK5 The KEYPRM signal (memory protection signal, parameter write
    setting) is:
    0 : Disabled.
    1 : Enabled.
    If that is not it then it is being done in the ladder.
