2) 32-bit instruction
A dead zone range is set in [S1+1, S1] and [S2+1, S2] and applied to the input value in [S3+1, S3]. The
resulting value is output to the element [D+1, D].
[S3+1, S3] – [S1+1, S1] -> [D+1, D] when [S1+1, S1] > [S3+1, S3];
[S3+1, S3] – [S2+1, S2] -> [D+1, D] when [S2+1, S2] < [S3+1, S3];
0 -> [D+1, D] when [S1+1, S1]≤ [S3+1, S3] ≤ [S2+1, S2].
Data overow conforms to cyclical processing during instruction execution. That is, the minimum value is
reached when the maximum value is incremented by 1; the maximum value is reached when the minimum
value is decremented by 1.
An error is returned in the following condition. The error ag M8067 is set to ON to identify this error and
the error code is stored in D8067.
For the 16- and 32-bit instructions, error 6706 is returned when the lower limit is greater than the upper
limit.

Overview
The ZONE instruction controls an output value by using the designated deviation value based on whether
the input value is positive or negative.
