Xn (X value), Yn (Y value)
Enter values for the X and Y coordinates. Three different data ranges are available depending on the system program
version and the data type.
Valid Data Types
CVXTY (Convert X to Y)
Applicable CPU Modules
Valid Operands
For the valid operand number range, see pages 6-1 and 6-2.
▲ Internal relays M0 through M1277 can be designated as D1. Special internal relays cannot be designated as D1.
When T (timer) or C (counter) is used as S2, the timer/counter current value is read out. When T (timer) or C (counter) is
used as D1, the data is written in as a preset value which can be 0 through 65535.

When a bit operand such as I (input), Q (output), M (internal relay), or R (shift register) is
designated as Xn or Yn, 16 points are used.
When a word operand such as T (timer), C (counter), or D (data register) is designated as Xn
or Yn, 1 point is used.
When input is on, the X value designated by operand S2 is conver ted
into corresponding Y value according to the linear relationship defined in
the XYFS instruction. Operand S1 selects a format from a maximum of
six XY conversion formats. The conversion result is set to the operand
designated by D1.
