FNC258 – ZONE / Zone Control
Outline
Depending on how the input value compares to positive or negative, the output value is controlled by the bias
value specified.
1. Instruction format
2. Set data
3. Applicable devices
Explanation of function and operation
1. 16-bit operation (ZONE and ZONEP)
The bias value specified by
or
is added to the input value specified by
, and output to the
device specified by
.
The bias value is added as shown below:
Operand Type
Description
Data Type
Negative bias value to be added to the input value
16- or 32-bit binary
Positive bias value to be added to the input value
Input value controlled by the zone
