6 Application Instructions API 00-49 API 26 Operands: S 1 : Source data device 1 S 2 : Source data device 2 D : Operation result Explanations: 1. If S 1 , S 2 and D are used in device F, only 16-bit instruction is applicable. 2. See the specifications of each model for their range of use. 3. This instruction conducts logical AND operation of S 1 and S 2 and stores the result in D . 4. Operation rule: The corresponding bit of the operation result in D will be “0” if any of the bits in S 1 or S 2 is “0”. Program Example 1: When X0 = On, the 16-bit D0 and D2 will perform WAND, logical AND operation, and the result will be stored in D4.
