z Thank you for choosing DELTA DVP Series PLC. The DVP06XA-S allows the connection of four analog
inputs and 2 groups 12 bits digital outputs (voltage/current). The PLC converts the input into a 12-bit digital
signal and the output into a 2 points analog signal, which then are manipulated by using TO and FROM
commands in the ladder logic program. There are 49 Controlled Registers (CR, each register has 16-bit) in
each module. The DVP06XA-S series can read/write the data by using commands FROM / TO via DVP-PLC
SS/SA/SX MPU program.

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(-1000LSB~+1000LSB).
Current setting range: -20mA~+20mA (-1000LSB~+1000LSB).

12.

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(-2000LSB~+2000LSB). Current setting range: -10mA~+10mA
(-2000LSB~+2000LSB).
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(-800LSB~+4000LSB). Current setting range: -16mA~+52mA (-800LSB ~+2600LSB). But it needs to
notice that GAIN VALUE - OFFSET VALUE = +200LSB~+3000LSB (voltage) or +200LSB~+1600LSB (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.
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(-1600LSB~+8000LSB). Current setting range: -8mA ~+40mA (-1600LSB~+8000LSB). Please be
noticed that GAIN VALUE – OFFSET VALUE = +400LSB ~+6000LSB (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.

Explanation:
z

Reading the model type of extension module K0 (should be HCC for DVP06XA-S model type).

z

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.

15.

CR#33 is used to set the internal function priority. For example: characteristic register. Output latched
function will save output setting in the internal memory before power loss.

Use the chart above to adjust D/A conversion characteristic curve of voltage output mode and current output
mode. Users can adjust conversion characteristic curve by changing OFFSET values (CR#14~CR#15) and GAIN
values (CR#18~CR#19) depend on application.

16.

CR#34: software version.

LSB (Least Significant Bit): 1. voltage output: 1LSB=10V/4000=2.5mV.

CR#35~ CR#48: system used.
The corresponding parameters address H 40C8~H 40F9 of CR#0~CR#48 will allow user to read/write data
via RS-485.
a)
Baud rate can be 4800, 9600, 19200, 38400, 57600, 115200bps.

2. current output: 1LSB=20mA/4000=5μA.

Adjust A/D Conversion Characteristic Curve of CH1~CH4

Explanation:
1.

Example: setting OFFSET value of CH1 to 0V(=K0LSB) and GAIN value of CH1 to 2.5V(=K500LSB).

Program Example for Adjusting A/D Conversion Characteristics Curve

Setting the average number of CH1 and CH2 are K32.

z
z

Reading the input signal average value of CH1~CH4 (4 data) from CR#6~CR#9 and save in D20~D23.

z

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.

z

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.
