Chapter 6 Applied Instructions Symbol S ： Matrix source n ： Length of the array D ： Pointer Explanation 6_ 1. This instruction checks the state of SM613. If SM613 is ON, the instruction clears the value of the pointer D to zero. The instruction reads the value of the bit specified by the value of the pointer D into SM614, and then checks the state of SM612. If SM612 is ON, the instruction increments the value of the pointer D by adding one. 2. When the instruction reads the value of the last bit, SM608 is ON, and the instruction stores the bit number in the pointer D . 3. The operand n must be between 1–256. 4. You specify the value of the pointer.
The values are between 0–16 n − 1, and correspond to the range between b0–b16 n − 1. If the value of the pointer exceeds the range, SM611 is set to one, and the instruction is not executed. 6-371 API Instruction code Operand Function 1212 MBRD P S, n, D Reading a matrix bit Device X Y M S T C HC D FR SM SR E K 16# “$” F S n D BOOL WORD DWORD LWORD UINT INT DINT LINT REAL LREAL TMR CNT STRING Data type S n D Pulse instruction 16-bit instruction 32-bit instruction ES3 ES3 -
