Chapter 6 Applied Instructions Symbol S ： First device D ： Device where the data is stored n ： Device where the data is deleted Explanation 6_ 1. For this instruction, the length of the data is the value in the device specified by S , and the data itself is in the devices specified by S +1– S +(the value in S ). This instruction stores the data in the device specified by S + n in D and deletes it, shifts the data in the devices specified by S + n + 1 – S +(The value in S ) to the right, clears the data in the device specified by S +(the value in S ) to 0, and decrements the value in the device specified by S by one.
When the value in the device specified by S is equal to 0, the instruction stops deleting the data, and sets the zero flag SM600 is ON. 2. In general, the SFDELP pulse instruction is used. 3. The operand n must be between 1–32767. 6-323 API Instruction code Operand Function 1107 SFDEL P S, D, n Deleting data from a data list Device X Y M S T C HC D FR SM SR E K 16# “$” F S D n BOOL WORD DWORD LWORD UINT INT DINT LINT REAL LREAL TMR CNT STRING Data type S D n Pulse instruction 16-bit instruction 32-bit instruction ES3 ES3 -
