Deleting Data Files
There are two ways to delete the contents of data files:
•
Clear memory- to delete your entire processor file, including all files except
the system program file (0) and the status data file (2).
•
Use the memory map function- to delete data in individual files or portions of
files. For example, you can delete blocks of addresses that have been allocated
but are not being used.
Not Used
Not Used
Allocated Space
You cannot delete

You can delete

You can delete binary, timer, counter, control, and integer elements. You cannot
delete an element if it is used in your program. Neither can you delete an unused
element if a higher numbered element in the file is used in your program. For
example, if you are using element B3:5, you cannot delete B3:0 through B3:4, even
if you aren’t using them in your program. If you try to delete them, the error
message
DATA TABLE FILE ADDRESS USED IN PROGRAM is displayed.
Note Make certain that you do not inadvertently delete data originally reserved for
indexed addressing. Unexpected operation will result.
