Notes on operand usage:
The operand D occupies three consecutive points. Refer to the
function specifications table for each device in series for the scope
of device usage.
S : Binary floating point number 1. S

1
Results of comparison, occupies three consecutive points.
 Compares binary floating point number 1 with binary floating point number 2,
and stores the result of comparison (>, =, <) in D.
 If the source operand S
converts the constant to a binary floating point number for the purpose of
comparison.
 When the designated device is M10, it automatically occupies M10-M12.
 When X0 = ON, the DECMP command executes, and one of M10–M12 is ON.
When X0 = OFF, the DECMP command does not execute, and M10–M12
remains in the X0 = OFF state.
 For ≥, ≤, or ≠ comparison results, use series and parallel connections for M10–
M12.
 Use the RST or ZRST command to clear the result.
