7 APPLICATION INSTRUCTION
7.10 Data control instruction
Dead band control of 16-bit binary data
BAND(P)(_U)
These instructions control the output value to be stored in the device specified by (d) by checking the input value (16-bit binary
data) in the device specified by (s3) with the upper and lower limit values of the dead band specified by (s1) and (s2).

Processing details
• These instructions control the output value to be stored in the device specified by (d) by checking the input value (16-bit
binary data) in the device specified by (s3) with the upper and lower limit values of the dead band specified by (s1) and (s2).
The output 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.
