binary value of 0000 to 0FA0 for an Analog Output Unit. When CIO 000000
turns ON in the following example, the contents of D00000 is scaled using the
linear function defined by X (0200), Y (0FA0), and the offset (0). These val-
ues are contained in D00100 to D00102. The sign of the BCD value in
D00000 is indicated by the Carry Flag. The result is output to CIO 2011.

N: Number of Cycles
The number of cycles must be between 0001 and 0040 hexadecimal (0 to 64
cycles).
R: Result Word and R+1: First Work Area Word
R will contain the average value after the specified number of cycles. R+1 pro-
vides information on the averaging process and R+2 to R+N+1 contain the
previous values of S as shown in the following diagram.
