Notes on operand usage:
The content value of operand S1 is less than the content value of
S2 operand.
The operand D occupies three consecutive points.
 S1: Lower limit of range comparison. S2: Upper limit of range comparison. S:
Comparative value. D: Results of comparison.
 Compares value S with the lower limit S1 and upper limit S2, and stores the
results of comparison in D.
 When lower limit S1 > upper limit S2, the command uses the lower limit S1 as
the upper and lower limit.
 Size comparison is performed algebraically. All data is compared in the form of
numerical binary values. Because this is a 16-bit command, when b15 is 1, this
indicates a negative number.
 When the designated device is M0, it automatically occupies M0, M1 and M2.
 When X0 = ON, the ZCP command executes, and M0, M1 or M2 is ON. When
X0 = OFF, the ZCP command does not execute, and the state of M0, M1 or M2
remains in the state prior to X0 = OFF.
 For ≥, ≤, or ≠ comparison results, use series and parallel connections for M0–
M2.
 To clear results of comparison, use the RST or ZRST command.
