[Description]
The data is written into the parameter area of the CNC.
The parameters of the CNC are classified into four types according to the
smallest unit that has a meaning. Bit parameter: Each bit has a meaning.
Byte parameter: Each byte has a meaning. Word parameter: Each set of
two bytes has a meaning. Double word parameter: Each set of four bytes
has a meaning.
Each bit of a bit parameter cannot be written individually. The eight bits
(one byte) of the parameter must be written at a time. To change a bit of
a bit parameter, read the entire parameter, change the desired bit, then
write the entire parameter.

(Note 1) Format of parameter data
If the data is one byte long, it is set in the DATA+0 area.
NOTE
For the PMC–NB6, real–type parameters cannot be written,
causing a CTL ERROR to occur.
