I have 3 racks and 15 Input Digital cards.
Im Mapping Digital Inputs to the memory and memory to variable

I map them like this :

%I0.2.0 --- Move ----%MW1.0
...

%I0.2.15 --- Move ----%MW1.15
...
%I0.11.15 --- Move ----%MW10.15

but I always receive this warning

Warning: '%MW10.11' statement is in memory overlapping due to mapping on variable(s) or due to equivalent '%MW10' address(es) or extracted bit(s) writing.


Please helppppppp
 
Apparently the MOVE command in your software (as in most PLC software) is designed to move even words, so if you try to move bits that do not start at word boundaries, you get problems.

If you figure out the Move's so that you are always moving 16 or 32-bit words, the warning should go away.
