1. Continuous execution and pulse execution function instructions have two types of continuous execution and pulse execution. As shown in Figure 1, the instruction mnemonic MOV is followed by a "P" indicating pulse execution, that is, the instruction is executed only when X1 is turned on (from OFF to ON) (send the data in D10 to D12) once; If there is no "P", it means continuous execution, that is, every scan cycle instruction of X1 ON is executed. 
Figure 1 shows the execution of the function instructions and the representation of the data length. The data length function instruction can process 16-bit data or 32-bit data. The instruction to process 32-bit data is preceded by a "D" flag in the mnemonic. Without this flag, it is an instruction to process 16-bit data. Note that a 32-bit counter (C200 to C255) has a 32-bit device and cannot be used as an operand for processing a 16-bit data instruction. As shown in Figure 3-27, if the MOV instruction is preceded by a "D", when X1 is turned on, D11D10 → D13D12 (32 bits) is executed. When using 32-bit data, it is recommended to use an operand whose first number is even, which is not easy to make mistakes.
