 When X1 goes from On to Off, set M0 = On to disable the adjustment on D/A conversion curve. Write K1
(H’1) into CR#40 b0=1 to disable
CH1 set value changing.

2.7.4 Adjusting D/A Conversion Curve in Current Output Mode 1 and Mode 2
1.
Description
 Tak e 0 4D A C H1 fo r e xa mple , w h en CR #2 is se t a s current output mode (mode 1), the Offset value will be
set as 0mA (0) and Gain value as 10mA (10mA/0.625A=16,000), i.e. output current 0mA ~ +20mA will
correspond to values 0 ~ +32,000.
 When CR#2 is set as current output mode (mode 2), the Offset value will be set as 4mA
(4mA/0.625A=6,400) and Gain value as 12mA (12mA/0.625A=19,200), i.e. input current 4mA ~
+20mA will correspond to values 0 ~ +32,000.
 If you cannot use the default current output mode (mode 1 and mode 2), you can make adjustments on
the D/A conversion curve according to your actual needs. For example, set the Offset of CH1 as 6mA
(6mA/0.625A=9,600) and Gain as 13mA (13mA/0.625A=20,800).

 You only need to set up the D/A conversion curve for once. Set up CR#40 (Set value changing prohibited)
to prevent incorrect operations.

3. Devices
 X0 = On: Set the output mode of the signals at CH1 as mode 1.
 X1 = On: Set Offset value of CH1 as 6mA (9,600) and Gain value as 13mA (20,800).
 M0 = On: Disable CH1 set value changing.
4. Program explanation
 When X0 = On, set CR#2 as K1 (H’0001) and the signal output mode at CH1 as mode 1 (current output
mode).
 When X1 = On, write K9,600 (Offset value of CH1) into CR#28 and K20,800 (Gain value of CH1) into
CR#34.
 When X1 goes from On to Off, set M0 = On to disable the adjustment on D/A conversion curve. Write K1
(H’1) into CR#40 b0=1 to disable
CH1 set value changing.
