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.
Condition
Lower limit value of the dead band (s1) > Input value (s3)
Upper limit value of the dead band (s2) < Input value (s3)
Lower limit value of the dead band (s1)  Input value (s3)  Upper limit value of the dead band (s2)

• 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.
Ex.
When (s1) is 10 and (s3) is -32768: Output value = -32768-10 = 8000H-000AH = 7FFFH = 32758
• When the output value to be stored in the device specified by (d) is a 16-bit unsigned binary value and the operation result
exceeds the range of 0 to 65535, the output value is calculated as follows.
Ex.
When (s1) is 100 and (s3) is 50: Output value = 50-100 = 0032H-0064H = FFCEH = 65486
Operation error
Error code Description
(SD0/SD8067)
3405H The lower limit value specified by (s1) is greater than the upper limit value specified by (s2).
(s3)
Output value
Input value (s3) - Lower limit value of the dead band (s1)
Input value (s3) - Upper limit value of the dead band (s2)
