The previous steps ensure that only the archive file is renamed. Documentation
and symbol files will be untouched. Refer to chapter 5 in this manual for more
information on renaming files.

Data Table File Size
Online editing cannot change the size of existing data tables nor can new ones be
created. However, some ladder instructions, when programmed cause data table
values to change. These instructions are those that require timer, counter, and
control addresses to be specified.
APS sends new data table values associated with an instruction insertion or
modification to the processor when the rung is accepted. For example, if a Timer
On-Delay (TON) instruction is inserted, the preset and accumulator values are sent
to the processor when the rung is accepted.
Once you accept the rung the data table values are applied and the message: DATA
TABLE VALUES HAVE BEEN PERMANENTLY MODIFIED is displayed.
Note that only unprotected data table values changed in the processor.
If the data table file being modified is constantly protected, APS displays the
message:
CANNOT MODIFY PROTECTED DATA FILE DURING ONLINE
EDITING .
Refer to chapter 8 for more information about data table file protection.
Note Data values associated with the “original version” of your program may be
overwritten with the Runtime Online Edits. This is because “new” data values are
applied to the program when you accept the rung, not when you test edits. Also, the
original version of your program will operate using the new data.
If you perform an online edit that changes statically protected data file values, you
will be prompted to either accept the edit without the data file changes or to abort
the edit.
