DVP06XA-S

Analog Input/Output Mixed Module

Instruction Sheet

Please carefully read this instruction thoroughly prior to use the DVP06XA-S.

In order to prevent electric shock, do not touch the terminals or conduct any maintenance while

PLC is power on. to conduct the internal electrical work on PLC.

This is an OPEN-TYPE device and already certified to meet the IEC 61131-2 (UL 508) safety

requirements when installed in an enclosure.

DVP06XA-S must be placed in an environment away from high temperatures, high humidity,

exceessive vibration, corrosive gases, liquids, airborne dust, and metallic particles.

Do not apply AC power to any of the input/output terminals, or it may cause permanent damage to

the DVP06XA-S.

Do not touch the internal circuit for at least 1 minute after the power supply is Off.

Make sure that DVP06XA-S is properly grounded , to avoid any electromagnetic noise.

2.1 Model Explanation and Peripherals

 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.

 Software version of DVP06XA-S analog input/output mixed module can be updated via RS-485.

Power supply and main processing units are sold separately.

 Users can select input from voltage or current via wiring. Voltage input range is ±10V DC

(resolution is 5 mV) and current is ±20mA (resolution is 20 µA).

 Users can select output from voltage or current via wiring. Voltage output range is 0V ~ +10V DC

(resolution is 2.5 mV) and current is 0mA ~ 20mA (resolution is 5 µA).

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 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:

LSB

 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.
