AH500 Programming Manual Symbol: D ： Device involved in the shift Word n ： Number of bits Word Explanation: 1. The values of the bits in D are shifted by n bits to the left. The vacancies (b0~b n -1) resulting from the shift is filled by 0, and the value of b16- n is transmitted to SM602. 2. The operand n should be within the range between 1 and 16. 3. Generally, the pulse instruction SFLP is used. Example: When X0.0 is ON, the values of b0~b15 in D0 are shifted by 6 bits to the right, and the value of b10 is transmitted to SM602. The values of b0~b5 are cleared to 0 after the shift. The shift of the values of the bits to the left during a scan is illustrated as follows.
b15~b10 → Being carried (The value of b10 is transmitted to SM602. b9~b0 → b15~b6 0 → b5~b0 Carry flag b0 b15 ※ After the shift Carry flag b0 b15 1 Being filled by 0 Additional remark: If n is less than 0, or if n is larger than 16, the instruction is not executed, SM0 is ON, and the error code in SR0 is 16#200B. 6-256 API Instruction code Operand Function 1111 SFL P D, n Shifting the values of the bits in the 16-bit registers by n bits to the left Device X Y M S T C HC D L SM SR E PR K 16# “$” DF D n Pulse instruction 16-bit instruction (5 steps) 32-bit instruction AH500 AH500 - 0 0 0 0 1 1 1 1 0 0 0 0 1 1 1 1 1 1 0 0 0 0 1 1 1 1 0 0 0 0 0 0
