Cvytx (Convert Y To X) - IDEC FC4A-C10R2 User Manual

S1 (Format number)
Select a format number 0 through 5 which have been set using the XYFS instruction. When an XYFS instruction with
the corresponding format number is not programmed, or when XYFS and CVXTY instructions of the same format
number have different data type designations, a user program execution error will result, turning on special internal
relay M8004 and the ERR LED.
S2 (X value)
Enter a value for the X coordinate to convert, within the range specified in the XYFS instruction. Any value out of the
range specified in the XYFS results in a user program execution error, turning on special internal relay M8004 and the
ERR LED. Three different data ranges are available depending on the system program version and the data type.
D1 (Destination to store results)
The conversion result of the Y value is stored to the destination. The data range depends on the available data type.

When a bit operand such as I (input), Q (output), M (internal relay), or R (shift register) is
designated as S2 or D1, 16 points are used.
When a word operand such as T (timer), C (counter), or D (data register) is designated as S2
or D1, 1 point is used.

When input is on, the Y value designated by operand S2 is converted
into corresponding X 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.
