Notes on operand usage:
The operand D occupies three consecutive points
Please refer to the function specifications table for each device in
series for the scope of device usage

S
1
: Lower limit of binary floating point number in range comparison.
S
2
: Upper
limit of binary floating point number in range comparison.
S
: Comparison of
binary floating point numerical values.
D
: Results of comparison, occupies 3
consecutive points.
 Comparison of binary floating point numerical value
S
with binary floating point
number lower limit value
S
1
and binary floating point number upper limit value
S
2
;
the results of comparison are expressed in
D
.

If the source operand S
1
or
S
2
designates a constant K or H, the command will
transform the constant to a binary floating-point number for the purpose of
comparison.

When the lower limit binary floating point number
S
1
is greater than the upper
limit binary floating point number
S
2
, a command will be issued to perform
comparison with the upper and lower limits using the binary floating point number
lower limit value
S
1
.
 When the designated device is M0, it will automatically occupy M0- M2.
 When X0=On, the DEZCP command will be executed, and one of M0-M2 will be
On. When X0=Off, the EZCP command will not execute, and M0-M2 will continue
in the X0=Off state.
 Please use the RST or ZRST command to clear the result.
