Operands:
S
1
: Lower bound of zone comparison S
2
: 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
1
~ S
2
and the result (＞, ＝, ＜) is indicated by
three bit devices in D.
2. If the source operand S
1
or S
2
is specified as constant K or H, the integer value will
automatically be converted to binary floating point for comparison.
3. 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.
