3. Devices
 X0 = On: Set the output mode of the signals at CH5 as mode 0.
 X1 = On: Set Offset value of CH5 as 2V (6,400) and Gain value as 6V (19,200).
 M0 = On: Disable CH5 set value changing.
4. Program explanation
 When X0 = On, set CR#6 as K0 (H’0000) and the signal output mode at CH5 as mode 0 (voltage output
mode).
 When X1 = On, write K6400 (Offset value of CH5) into CR#32 and K19,200 (Gain value of CH5) into
CR#38.
 When X1 goes from On to Off, set M0 = On to disable the adjustment on D/A conversion curve. Write
K16 (H’10) into CR#40 b4=1 to disable
CH5set value changing.

3.7.7 Adjusting D/A Conversion Curve in Current Output Mode 1 and Mode 2
1.
Description
 Take 06XA CH6 for example. When CR#7 is set as 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#7 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 CH6 as 6mA
(6mA/0.625A=9,600) and Gain as 13mA (13mA/0.625A=20,800).
