7 APPLICATION INSTRUCTION
7.10 Data control instruction
Zone control of 16-bit binary data
ZONE(P)(_U)
These instructions add the bias value specified by (s1) or (s2) to the input value specified by (s3), and store the operation
result in the device specified by (d).
■Descriptions, ranges, and data types
■Applicable devices
• These instructions add the bias value specified by (s1) or (s2) to the input value (16-bit binary data) specified by (s3), and
store the operation result in the device specified by (d). The bias value is controlled as follows.
• When the output value to be stored in the device specified by (d) is a 16-bit signed binary value and the operation result
exceeds the range of -32768 to 32767, the output value is calculated as follows.
