AH500 Programming Manual API 1115 Symbol: D ： Initial device involve in the shift Word n ： Data length Word Explanation: 1. The data in the n registers starting from D is shifted to the left, and the data in D is cleared to 0. 2. Generally, the pulse instruction NSFLP is used. 3. The operand n should be within the range between 1 and 512. Example: When X0.0 is ON, the data in D0~D5 is shifted to the left, and the data in D0 is cleared to 0. D6 D0 D1 D2 D3 D4 D5 After the shift D6 D0 D1 D2 D3 D4 D5 Being cleared to 0 Additional remark: 1. If D + n -1 exceeds the device range, the instruction is not executed, SM0 is ON, and the error code in SR0 is 16#2003. 2.
If n is less than 1, or if n is larger than 512, the instruction is not executed, SM0 is ON, and the error code in SR0 is 16#200B. 6-260 Instruction code Operand Function NSFL P D, n Shifting n registers 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 - 30 2235 9578 754 28 423 11 2235 9578 754 28 423 11 0
