    Common Variables

    On Fanuc 21i-TB is there a parameter number to lock the common variables #500 to #531 so they can not be changed or deleted?

    Not That I'm Aware of...I ussually store them in a 8000 or 9000 series program and then lock those programs, and use a sub program call to reload the variables before I need them ...Just incase anybody changed anything they will always get reloaded....

    example:
    O0001(main program)

    M98 P9000

    "progam needing variables"


    M30
    %

    O9000(VARIABLES LIST)
    #500=??
    #501=??
    #502=??
    etc.
    M99
    %

    param 3202 bit 4 (NE9) locks 9000 series and bit 0 (NE8) locks 8000 series programs...
