DVP02DA-S

DVP02DA-S Analog Output Module

Instruction Sheet

1 WARNING

Please carefully read this instruction thoroughly prior to use the DVP02DA-S.

The DC input power must be OFF before any maintenance.

This is an OPEN-TYPE built-in DVP02DA-S, and the DVP02DA-S is certified to meet the safety

requirements of IEC 61131-2 (UL 508) when installed in the enclosure to prevent high

temperature, high humidity, exceessive vibration, corrosive gases, liquids, airbome dust or

metallic particles. Also, it is equipped with protective methods such as some special tool or key

to open the enclosure, so as to avoid the hazard to users or any damage to the DVP02DA-S.

Do not connect the AC power to any of the input/output terminals, or it may the DVP02DA-S.

Make sure that all the wiring is well conducted prior to power On.

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

Make sure that DVP02DA-S is properly grounded , to avoid any electromagnetic noise.

2 INTRODUCTION

2.1 Model Explanation and Peripherals

 Thank you for choosing DELTA DVP PLC Series. The analog output module of DVP02DA-S series

can read/write the data of analog output module by using commands FROM / TO via DVP-PLC

SS/SA/SX Series MPU program. The analog output module receives 2 group 12-bit digital data

from PLC MPU and converts it into 2 points analog output signal (voltage or current). There are 49

CR (Control Register) in each module and there are 16 bits in each register.

 The software version of DVP02DA-S analog output module can be updated via RS-485

communication. Power unit and module are separate. Size is small and easy to install.

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

(resolution is 2.5 mV). Current output range is 0mA ~ 20mA (resolution is 5 µA).

LSB (Least Significant Bit): 1. Voltage output: 1LSB=10V/8000=2.5mV. 2. Current output: 1LSB=20mA/4000=5µA.

Explanation:

1. The content of CR#0 is model type, user can read the data from program to check if there is

expansion module.

2. CR#1 is used to set two internal channels working mode of analog output module. Every channel

has four modes to set that can set individually. For example: if set CH1 to mode 2 (b2~b0=010),

CH2 to mode 1(b5~b3=001). It needs to set CR#1 to H000A. The factory setting of CR#1 is H0000.

3. CR#2 ~ CR#9, CR#12 ~ CR#21, CR#24 ~ CR#27 Reserved.

4. CR #10 ~ CR#11 display CH1 and CH2 output signal. The setting range is K0~K4000. Factory

setting is K0 and unit is LSB.

5. R#22 ~ CR#23 means the value to adjust OFFSET value of CH1 and CH2. The factory setting is K0

and unit is LSB. If output value equal to 0 after calculating, the adjustable range of analog output

voltage or current is -2000~+2000.

Voltage adjustable range: -5V~+5V(-2000LSB~+2000LSB).

Current adjustable range: -10mA~+10mA (-2000LSB~+2000LSB).

6. R#28 ~ CR#29 means the value of adjust GAIN value of CH1 and CH2. The factory setting is K2000

and unit is LSB. If output value equal to 2000 after calculating, the adjustable range of analog output

voltage or current is -1600~+8000.

Voltage adjustable range: -4V~+20V(-1600LSB~+8000LSB).

Current adjustable range: -8mA ~+40mA (-1600LSB~+8000LSB).

Please be noticed that GAIN VALUE – OFFSET VALUE = +400LSB ~+6000LSB (voltage or

current). When this value within this range, the resolution of the output signal will be thin and the

value variation will be larger. When this value exceeds this range, the resolution of output signal

will be thick and the variation of value will be smaller.

Example

 Using the 32-bit command DTO. The program will write D11 and D10 into CR#3

and CR#2 of special module#0. DTO only allows one group of data to be written at

a time (n=1).

 Command is executed when X0=ON, command won’t be executed when X0=OFF,

and the stored data will have no change.

X0

DTO K0

Footnote

 The rules for adding multiple special modules to a Main Processing Unit:

 m1: The maximum number of special modules attached to an MPU is 8. The

order of module closest to the MPU is 0, and the module furthest from the

MPU is 7.

 m2: The number of Controlled Registers (CR) built in is 49. (#0~#48).

 FROM/TO command read/write 16-bit CR data in one command, while

DFROM/DTO command to read/write 32-bit CR data in one command.

Example below:

Upper 16-bit Lower 16-bit

 In ES series models, flag M1083 is not provided. When FROM/TO command is

executed, all interrupts (including external or internal interrupt subroutines) will be

disabled. All interrupts will be executed after FROM/TO command is completed.

Besides, FROM/TO command also can be executed in the interrupt subroutine.

 The function of the flag M1083 (FROM/TO mode exchange) provided in EP/EH

series models:

1. When M1083=Off, all interrupts (including external or internal interrupt

subroutines) will be disabled when FROM/TO command is executed. The

Interrupts will resumed after FROM/TO command complete. Please be

advised FROM/TO command can be executed in the interrupt subroutine.

2. When M1083=On, if an interrupt enable occurs while FROM/TO command are

executing, the interrupt FROM/TO command will be blocked till the requested

interrupt finish. Unlike M1080 off situation, FROM/TO command cannot be

executed in the interrupt subroutine.
