The ACTIVE_UNITS data item is used to identify the current
operating mode, in terms of measurement system, being used on the
control. The returned value is enumerated as follows:
Enumeration Result:
2118 Inch Mode
2119 Metric Mode
AXIS_RAD_DIA_MODE
Data Type
DINT (bit pattern)
Read/Write Read only
Array Index none
Control Type Lathe/Mill/Grinder 1
1 Grinder Control Type is not available for Release 1 of 9/PC.
The AXIS_RAD_DIA_MODE data item is used to identify which
axes on the system are currently in radius or diameter mode (refer to
your Lathe or Grinder Operation and Programming Manual for
details on radius/diameter mode). The data for this item is returned
as a bit pattern. A true value in any bit indicates that the axis is in
diameter mode. The first bit of this word represents axis 1.
For example if the returned integer is 8, which translates into 01000
indicating the fourth axis is in diameter mode.
On Mill controls all axes are always in radius mode (all bits of this
word remain zero). Only one axis can be in diameter mode on a
Lathe. Grinders can have multiple axes in diameter mode.
