Chapter 6 Applied Instructions Symbol: S ： Initial device Word D ： Data which is inserted Word n ： Device into which the data is inserted Word Explanation: 1. The value in the device specified by S indicates the length of the data, and the data is in the devices specified by S +1~ S +(The value in S ). When the instruction is executed, the data in D is inserted into S + n , the original data in the devices specified by S + n ~ S +(The value in S ) is shifted to the left, and the value in the device specified by S increases by one.
When the value in the device specified by S is equal to 32767, the instruction does not process the writing of the data, the value in the device specified by S does not increase, and the carry flag SM602 is ON. 2. Generally, the pulse instruction SFINSP is used. 3. The operand n should be within the range between 1 and 32767. Example: Suppose the value in D0 is 8, and n is 4. When X0.0 is ON, the data in D200 is inserted into D4, the original data in D4~D8 is shifted to D5~D9, and the value in D0 increases by one. S D n=4 D200 D8 D7 D6 D5 D4 D3 D2 D1 D0 22 The data is inserted.
