Protection
8–15
If the file is Static protected and you want to change it to Constant protection,
the prompt:
File(s) already STATIC protected. Do you wish
to alter protection? is displayed.
If you attempt to apply Constant protection to Input, Output, and/or Status files,
your request will be acknowledged and the message:
INPUT, OUTPUT,
AND STATUS FILES CANNOT BE CONSTANT PROTECTED is
displayed.
If data table file protection is changed for any individual data file, the user program
must be saved before you leave the program directory screen in order for the new
data table file protection to be applied.
If you create additional data table files and you are using a SLC 5/03 or
SLC 5/04 processor, protection is set to the default protection value (unprotected).
When changing processor types from an SLC 5/03 or SLC 5/04 to a fixed, SLC
5/01, or SLC 5/02 processor, all of the data table files will have their protection set
to their default values.
If you attempt to modify the contents of a Static or Constant protected data table file
using a communications port, the request is denied and the message:
DATA VALUE
CANNOT BE MODIFIED DUE TO FILE PROTECTION is displayed.
