Operands:

2
: Binary floating point comparison value 2 D: Comparison
result
Explanations:
1. D occupies 3 consecutive devices.
2. See the specifications of each model for their range of use.
3. The binary floating point values S
1
and S
2
are compared with each other. The comparison result (>, =, <) is
stored in D.
4. If S
1
or S
2
is an designated constant K or H, the instruction will convert the constant into a binary floating point
value before the comparison.
Program Example:
1. Designated device M10 and M10 ~ M12 are automatically occupied.
2. When X0 = On. DECMP instruction will be executed and one of M10 ~ M12 will be On. When X0 = Off, DECMP
instruction will not be executed and M10 ~ M12 will remain their status before X0 = Off.
3. To obtain results , , ≠≧≦ , serial-parallel M10 ~ M12.
4. Use RST or ZRST instruction to clear the result.
