Chapter 6 Applied Instructions D100 D101 Parity bits 6_ Additional remarks 1. Suppose SM606 is ON. If S + n -1 exceeds the device range, the instruction is not executed, SM0 is ON, and the error code in SR0 is 16#2003. 2. Suppose SM606 is OFF. If S + n /2-1 exceeds the device range, the instruction is not executed, SM0 is ON, and the error code in SR0 is 16#2003. 3. If n is not between 1–256, the instruction is not executed, SM0 is ON, and the error code in SR0 is 16#200B. 4. If you declare the operand D in ISPSoft, the data type is ARRAY [2] of WORD/INT.
