29.3 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
Head device number storing the output value controlled by the zone
