After selecting the desired data table, select "Property" by clicking right mouse

Data Table Protection Requirements
Following are conditions for data table protection:
The PLC contains protected data table.
The ladder program being downloaded to the PLC has the same number of
protected data tables as the ladder program to be updated stored in the
internal PLC.
All protected data table numbers, types, and sizes (number of elements)
currently in the controller exactly match.
If all of these conditions are met, the X8 Series PLC will not write over any
data table in the PLC that is configured as Protected.
If any of these conditions are not met, the entire data table in the inte
r
nal PLC i
is updated with the contents from being sent XGPC.
TIP
The SFR (Special Function Register) cannot be protected.
