UR_UINT16 FLEXCURVE DATA (120 points)
A FlexCurve is an array of 120 consecutive data points (x, y) which
are interpolated to generate a smooth curve. The y-axis is the user
defined trip or operation time setting; the x-axis is the pickup ratio
and is pre-defined. Refer to format F119 for a listing of the pickup
ratios; the enumeration value for the pickup ratio indicates the off-
set into the FlexCurve base address where the corresponding time
value is stored.
F012
DISPLAY_SCALE DISPLAY SCALING
(unsigned 16-bit integer)
MSB indicates the SI units as a power of ten. LSB indicates the
number of decimal points to display.
Example: Current values are stored as 32 bit numbers with three
decimal places and base units in Amps. If the retrieved value is
12345.678 A and the display scale equals 0x0302 then the dis-
played value on the unit is 12.35 kA.
