AH500 Programming Manual API 0815~ 0817 Symbol: S 1 ： Data source 1 Word/Double word Taking OR& and DOR& for example S 2 ： Data source 2 Word/Double word Explanation: 1. The instruction is used to compare the data in S 1 with that in S 2 . When the comparison result is not 0, the condition of the instruction is met. When the comparison result is 0, the condition of the instruction is not met. 2. Only the instruction DOR ＃ can use the 32-bit counter. 3. The instruction OR ＃ and the contact are connected in parallel. 4. &: Logical AND operation 5. |: Logical OR operation 6. ^: Logical exclusive OR operation Example: 1. When X0.1 is ON, Y0.0 is ON.
Besides, when the logical operator AND performs the logical AND operation on each pair of corresponding bits in C0 and C10 and the operation result is not 0, Y0.0 is ON. 2. When X0.2 and X0.3 are ON, Y0.1 is ON. When the logical operator OR performs the logical OR operation on each pair of corresponding bits in the 32-bit register (D10, D11) and the 32-bit register (D20, D21) and the operation result is not 0, Y0.1 is ON. Besides, when the logical operator XOR performs the logical exclusive OR operation on each pair of corresponding bits in the 32-bit counter HC0 and the 32-bit register (D200, D201) and the operation result is not 0, Y0.1 is ON.
