2. 32-bit operation (DBAND/DBANDP)
Depending on how the input value (32-bit binary value) specified by compares to the upper and lower
limit dead band range between the devices specified by and , the output value to be stored in the
device specified by is controlled.
The output value is controlled as shown below.
