AS Series Programming Manual Symbol D ： First device for the shift n ： Data length Explanation _6 1. This instruction shifts the states of the n bit devices starting from D by one bit to the left. The instruction clears the state of D to 0, and transmits the state of D + n -1 to the carry flag SM602. 2. In general, the BSFLP pulse instruction is used. 3. The operand n must be between 1–1024. Example When X0.0 is ON, the instruction shifts the states of M0–M5 by one bit to the left, clears the state of M0 to 0, and transmits the state of M5 to the carry flag SM602.
