After selecting protect file, you can specify individual program files and/or
ranges of program files on which to apply the file protection. Refer to the
previous page for the different ways files can be listed. After successful
validation, program file protection is applied to the list of specified files.

If program file protection is changed, the user program must be saved before
you leave the program directory screen in order for the new program file
protection to be applied.

If you create additional program files, program file protection is set to No if the
current processor type is a SLC 5/03 or SLC 5/04. If the current processor type
is not a SLC 5/03 or SLC 5/04, protection is set to Yes.

When changing processor types from a SLC 5/03 or SLC 5/04 to a SLC 5/02 or
below processor, all of the program files will have file protection set to Yes.
When changing processor types from a fixed, SLC 5/01, or SLC 5/02 to a SLC
5/03 or SLC 5/04, all program files will have protection set to No.

Data Table File Protection

Data table file protection is available with any of the SLC 500 processors. It can
only be changed during offline programming.

Forms of Protection

Depending on the SLC 500 processor, two forms of data table file protection are
available:

Static - Changes to protected data values are only allowed by the ladder
program during program execution. Data values cannot be altered by
communication channels, but the values can be changed by the user program or
from the multi-point list. (This includes online edits.)

Constant - The file is protected from all changes. Data values cannot be altered
by communication channels, your ladder program, or multi-point lists. For
example, constantly protected data table files can be used for recipe storage or
look-up tables. The Input, Output, and Status files cannot be constantly
protected.
