DEZCP, DEZCPP: 12 steps
Operands:
S
1
: Lower bound of zone comparison
S
2
: Upper bound of zone comparison
S
: Comparison value
D
: Comparison result
Explanations:
1. The data of
S
is compared to the data range of
S
1
~
S
2
and the result (
＞
,
＝
,
＜
) is indicated by three bit
devices in
D
2.
D
occupies 3 consecutive devices.
3. F refers to floating point input. Be sure to add a decimal point when using it.
4. Only 32-bit instructions DEZCP and DEZCPP are applicable.
5. If
S
1
or
S
2
is specified with floating point value F, the instruction will operate in binary floating point.
6. Operand
S
1
should be smaller than operand
S
2.
When
S
1
>
S
2
, the instruction takes
S
1
as the 1
st
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.
