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.

If the X value becomes nega-
tive, a user program execution
error will result, turning on spe-
cial internal relay M8004 and
the ERR LED.
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 converted
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.
