Example:
1. When X0.0 is ON, the values in D10~D19 are compared with the value in D0, and the
comparison results are stored in D50~D54. When the equal value does not exist, the values in
D50~D52 are 0.
2. The data number of the minimum value is stored in D53, and the data number of the maximum
value is stored in D54. If there is more than one minimum value or maximum value, the data
number which is bigger is stored.

Additional remark:
1. If S +n-1 or D+4 exceeds the device range, the instruction is not executed, SM0 is ON, and the
1
error code in SR0 is 16#2003.
2. If the operand n used in the 16-bit instruction is less than 1 or larger than 256, the instruction is
not executed, SM0 is ON, and the error code in SR0 is 16#200B.
3. If the operand n used in the 32-bit instruction is less than 1 or larger than 128, the instruction is
not executed, SM0 is ON, and the error code in SR0 is 16#200B.
4. If the operand D used during the execution of the 16-bit instruction is declared in ISPSoft, the
data type will be ARRAY [5] of WORD/INT.
5. If the operand D used during the execution of the 32-bit instruction is declared in ISPSoft, the
data type will be ARRAY [5] of DWORD/DINT.
