Chapter 6 Applied Instructions API 0112 Symbol: S 1 ： Augend Word S 2 ： Addend Word n ： Data length Word D ： Sum Word 1. n pieces of data in devices starting from S 2 are added to those in devices starting from S 1 . The augends and the addends are binary numbers, and the sums are stored in D . 2. The operand n should be within the range between 1 and 256. 3. When the operation result is zero, SM600 is ON. 4. When the operation result is less than –32,768, SM601 is ON. 5. When the operation result is larger than 32,767, SM602 is ON. 6. When the operand S 2 is a device (not a constant or a hexadecimal value): Explanation: . . . . . S +n-1 1 2 } } . . . . .
