Dead band control of 32-bit binary data
DBAND(P)(_U)
These instructions control the output value to be stored in the device specified by (d) by checking the input value (32-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 (32-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.
Condition
Lower limit value of the dead band ((s1), (s1)+1) > Input value ((s3), (s3)+1)
Upper limit value of the dead band ((s2), (s2)+1) < Input value ((s3), (s3)+1)
Lower limit value of the dead band ((s1), (s1)+1) Input value ((s3), (s3)+1) Upper limit value of
the dead band ((s2), (s2)+1)
Output value (d+1, d)
Lower limit value of the
dead band (s1+1, s1)
• When the output value to be stored in the device specified by (d) is a 32-bit signed binary value and the operation result
exceeds the range of -2147483648 to 2147483647, the output value is calculated as follows.
