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
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 will be On. When
X0=Off, the ZCP command will not execute, and the state of M0, M1 or M2 will
remain in the state prior to X0=Off.
 If ≥, ≤, or ≠ results are needed, they can be obtained via series/parallel
connections of M0-M2.
To clear results of comparison, use the RST or ZRST command.
