Operands:

S1: Lower bound of zone comparison S2: Upper bound of zone comparison

S: Comparison

value D: Comparison result, 3 consecutive devices

Explanations:

1.The data of S is compared to the data range of S1 ~ 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.

3.Operand S1 should be smaller than operand S2. When S1 > S2, the instruction takes S1 as the 1st comparison value and performs normal comparison similar to ECMP instruction.

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, DEZCP instruction is not executed, M10~M12 will retain their previous state before X0 = OFF.

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

M11 = ON when (D1,D0) < (D21,D20) < (D11,D10)

M12

M12 = ON when (D21,D20)>(D11,D10)
