3.3.2 Inch/Metric Switching
For parameters dependent on inch/metric switching such as those for
length and feedrate, whether data is inch data or metric data is
specified by the input mode in the case of input from the MDI panel,
or by the keyword I or M prefixed to the data in the case of input from
an external I/O device. The keyword I or M is added also when data
is output from an external I/O device.
If the input mode or keyword differs from the actually used mode as
in a case where data input in the inch mode is used in the metric mode,
the CNC performs automatic data conversion. So, data need not be
converted according to a mode change. Moreover, when parameter
data is displayed, the data is converted according to the display mode.
However, when data is output from an external I/O device, the original
data is output according to the original keyword.
3.3.3 Bit Format
N ***** Q1 P ******** ;
A numeric value after N represents a parameter number.
Q1 indicates that the data is parameter data.
An 8-digit binary number after P represents the bit values (0/1) of a
parameter, with the first digit corresponding to bit 0 and the eighth
digit corresponding to bit 7.
Leading zeros may not be omitted.
A semicolon (;) marks the end of a block. (LF is used for the ISO
code, and CR is used for the EIA code.)
Example
N00010Q1P00000001;
Parameter No. 10
Parameter value
Bit 0 is set to 1, and the other bits are set to 0.
