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
the results of comparison are expressed in D.
If the source operand S
transform the constant to a binary floating-point number for the purpose of
comparison.
When the lower limit binary floating point number S
limit binary floating point number S
comparison with the upper and lower limits using the binary floating point number
lower limit value S .

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.
