CR# Attrib. Register name Explanation
#20 X R/W Set value of CH1 upper bound
Set value of CH1~CH4 upper bound.
Default = K32767. #21 X R/W
Set value of CH2 upper bound
#22 X R/W
Set value of CH3 upper bound
#23 X R/W Set value of CH4 upper bound
#24 X R/W Set value of CH1 lower bound
Set value of CH1~CH4 lower bound.
Default = K-32768. #25 X R/W
Set value of CH2 lower bound
#26 X R/W
Set value of CH3 lower bound
#27 X R/W Set value of CH4 lower bound
#28 X R/W Adjusted Offset value of CH1 Set the adjusted Offset value of CH1 ~ CH4.
Default = K0
Definition of Offset in DVP04AD-SL:
The corresponding voltage (current) input
value when the digital input value = 0.
#29 X R/W Adjusted Offset value of CH2
#30 X R/W Adjusted Offset value of CH3
#31 X R/W Adjusted Offset value of CH4
#34 X R/W Adjusted Gain value of CH1 Set the adjusted Gain value in CH1 ~ CH4.
Default = K16,000
Definition of Gain in DVP04AD-SL:
The corresponding voltage (current) input
value when the digital input value = 16,000.
#35 X R/W Adjusted Gain value of CH2
#36 X R/W Adjusted Gain value of CH3
#37 X R/W Adjusted Gain value of CH4
#42 X R/W
Function: Return to default
setting
b0 ~ b3: reset CH1 ~ CH4
b4 ~ b15: reserved
Default = H’0000. Give CH1 setting for
example: When b0 is set to 1, all settings are
reset to default setting.
#43 X R Error status
Register for storing all error status. Refer to
table of error status for more information.
Default = H’0000.
Symbols: O means latched. X means not latched.
R means can read data by using FROM instruction.
W means can write data by using TO instruction.

 Note: Each error status is determined by the corresponding bit and there may be more than 2
errors occurring at the same time. 0 = normal; 1 = error.
