Operands:

: Lower bound of zone comparison S

: 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 S

~ S

and the result (＞, ＝, ＜) is indicated

by three bit devices in D.

2. If the source operand S

or S

is specified as constant K or H, the integer value will

automatically be converted to binary floating point for comparison.

3. Operand S

should be smaller than operand S

When S

> S

, the instruction takes S

as the

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.
