Example
When R005 is ON, t he data of D0100 and the const ant data 1000 is added, and the r esult is
stored in D0110.
If t he data of D0100 is 12345, t he r esult 13345 is stored in D0110, and R010 is t ur ned O FF.
D0100 12345 +D0110 13345 R010 is OFF
Constant 1000
If t he data of D0100 is 32700, t he r esult exceeds the limit value, therefore 32767 is stored in
D0110, and R010 is turned O N.
D0100 32700 Overflow
