Explanation:
1. CR#0: The PLC model type.
2. CR#1: b11~b0 are used to set 4 internal channels working mode of analog input module (AD).
b12~b15 are used to set 2 channels working mode of analog output module (DA). Every channel
has four modes that can be set individually. For example: if setting CH1 to mode 0 (b2~b0=000),
CH2 to mode 1(b5~b3=001), CH3: mode2 (b8~b6=010), CH4: mode 3(b11~b9=011), b0~b11
need be set to H688. If setting CH5: mode 2 (b13~b12=10), CH6: mode 1 (b15~b14=01),
b12~b15 need be set to H5. The factory setting is H0000.
3. CR#2 ~ CR#5: Used to set the number of piece of input readings for the average temperature
calculation. The available range is K1~K4096 and factory setting is K10.
4. CR#6 to CR#9: The average value of temperature in ℃. Temperature is calculated by averaging
multiple temperature readings. Example: If CR#2 is 10, the temperature in CR#6 will be the
average of the last 10 readings on CH1.
5. CR#10 ~ CR#11 are used to set the output value of CH5 and CH6. The setting range is
K0~K4000. The factory setting is K0 and unit is LSB.
6. CR#12 ~ CR#15: used to save the present value of input signal of CH1~CH4.
7. CR#16, CR#17, CR#28, CR#29 are reserved.
8. CR #18~ CR #21: used to adjust the OFFSET value of CH1~CH4 if analog input either in voltage
or in current is 0 after it converts from analog to digital. Voltage setting range:
-5V~+5V(-1000
LSB
~+1000
LSB
). Current setting range: -20mA~+20mA (-1000
LSB
~+1000
LSB
).
9. CR #22~ CR #23: used to adjust the OFFSET value of CH5~CH6 if analog input either in voltage
or in current is 0 after it converts to digital. Factory setting is K0, and the unit is
LSB
. The setting
range is -2000~+2000. Voltage setting range: -5V~+5V(-2000
LSB
~+2000
LSB
). Current setting
range: -10mA~+10mA (-2000
LSB
~+2000
LSB
).
10. CR #24~ CR #27: used to adjust the GAIN value of CH1~CH4. The value of analog input either
in voltage or in current after it was converted to digital based upon full scale of 4000. Voltage
setting range: -4V~+20V(-800
LSB
~+4000
LSB
). Current setting range: -16mA~+52mA (-800
LSB
~+2600
LSB
). But it needs to notice that GAIN VALUE - OFFSET VALUE = +200
LSB
~+3000
LSB
(voltage) or +200
LSB
~+1600
LSB
(current). If the value difference comes up small (within range),
the output signal resolution is then slim and the variation is definitely larger. On the contrast, if
the value difference exceeds the range, the output signal resolution becomes larger and the
variation is definitely smaller.
11. CR #28~ CR #29: used to adjust the GAIN value of CH5~CH6. The value of analog input either
in voltage or in current after it converts to digital based upon full scale of 2000. Voltage setting
range: -4V~+20V(-1600
LSB
~+8000
LSB
). Current setting range: -8mA ~+40mA (-1600
LSB
~+8000
LSB
).
Please be noticed that GAIN VALUE – OFFSET VALUE = +400
LSB
~+6000
LSB
(voltage or current).
If the value difference comes up small (within range), the output signal resolution is then slim
and the variation is definitely larger. On the contrast, if the value difference exceeds the range,
the output signal resolution becomes larger and the variation is definitely smaller.

6 Initial PLC Start-up
Lamp display:
1. Upon power-up, the ERROR LED will light for 0.5 seconds the POWER LED will light
continuously.
2. No errors= POWER LED on and ERROR LED off.
Low Voltage error (lower than 19.5V), ERROR LED will blink continuously till the power
supply rises above 19.5V.
3. DVP06XA-S connected to PLC MPU in series = RUN LED on MPU will be lit and A/D LED
or D/A LED should blink.
4. After receiving the first RS-485 command the A/D LED or D/A LED will blink.
5. If the input or output exceeds the upper or lower bounds, then the ERROR LED will blink.
6. When main CPU and expansion unit communicate time-out or abnormal interrupt, LED
ERROR of expansion unit will keep lighting.

Explanation:
Reading the model type of expansion module K0 (should be HCC for DVP06XA-S model type).
If the model type is DVP06XA-S, set the input mode is (CH1, CH3, CH4)= mode 0, (CH2)= mode 2,
and set the output mode is (CH5)=mode 0, (CH6)=mode 2.
Setting the average number of CH1 and CH2 are K32.
Reading the input signal average value of CH1~CH4 (4 data) from CR#6~CR#9 and save in
D20~D23.
In each second, D100 will increase K1 and D101 will increase K5. When the value of D100 and
D101 are K4000, it will clear to 0.
Writing the output setting value of D100 and D101 into CR#10 and CR#11. The analog output value
of CH5~CH6 will change with the value of D100 and D101.
