Operands:

S1: 1st comparison value

S2: 2nd comparison value D: Comparison result, 3 consecutive

devices

Explanations:

1.The data of S1 is compared to the data of S2 and the result (＞, ＝, ＜) is indicated by three bit devices in D.

2.If the source operand S1 or S2 is specified as constant K or H, the integer value will automatically be converted to binary floating point for comparison.

Program Example:

1.If the specified device is M10, M10~M12 will automatically be used.

2.When X0 = ON, one of M10~M12 will be ON. When X0 = OFF, DECMP is not executed, M10~M12 will retain their previous state before X0 = OFF.

3.Connect M10~M12 in series or parallel for achieving the results of ≧, ≦, ≠.

4.RST or ZRST instruction is required if users need to reset the comparison result.

M10

M10 = ON when (D1,D0)>(D101,D100)

M11

M11 = ON when (D1,D0)=(D101,D100)

M12

M12 = ON when (D1,D0)<(D101,D100)
