Please carefully read this instruction thoroughly prior to use the DVP04AD-H.
The DC input power must be OFF before any maintenance.
This is an OPEN-TYPE built-in DVP04AD-H, and the DVP04AD-H 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, in order to prevent the hazard to users and the damage to the DVP04AD-H.
Do not connect the AC power to any of the input/output terminals, or it may damage the
DVP04AD-H. 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 OFF.
Make sure that the DVP04AD-H is properly grounded
, to prevent any electromagnetic noise.

INTRODUCTION
Model Explanation and Peripherals
Thank you for choosing DELTA’s PLC DVP Series. The analog input module receives external
4-point analog signal input (voltage or current) and converts it into 14 bits digital signal. The
analog input module of DVP04AD-H series can read/write the data of analog input module by
using instructions FROM / TO via DVP-PLC EH Series MPU program. There are 49 CR (Control
Register, each register has 16-bit) in each module.
Software version of DVP04AD-H analog input module can be updated via RS-485 communication.
Users can select input from voltage or current via wiring. Voltage input range is
±10V
DC
(resolution is 1.25 mV). Current input range is
±20
mA (resolution is 5 µA).

Explanation:
1. CR#0: The content of CR#0 is model type, user can read the data from program to know if there
is extension module.
2. CR#1: CR#1 is used to set 4 internal channels working mode of analog input module. Every
channel has four modes to set and 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). It needs to set CR#1 to H0688 and the upper bit (b12~b15) will reserved. The
factory setting of CR#1 is H0000.
3. CR#2 ~ CR#5: it is used to set average times of CH1~CH4. Setting range is K1~K4096 and
factory setting is K10.
4. CR#6 to CR#9 are the average value that calculates according to the value that is set in
CR#2~CR#5 (average time of CH1~CH4 input signal). For example, if CR#2 (the average times
of CH1) is 10, it will calculate the average of CH1 input signal every 10 times.
5. CR#10, CR#11, CR#16, CR#17, CR#22, CR#23, CR#28, CR#29 reserved.
6. CR#12 ~ CR#15: display present value of CH1~CH4 input signal.
7. CR #18~ CR #21: the content is the value of adjusting OFFSET value of CH1~CH4 if analog
input voltage or current is 0 after it transfers from analog to digital. Voltage setting range:
-5V~+5V(-4000
LSB
~+4000
LSB
). Current setting range: -20mA~+20mA (-4000
LSB
~+4000

).
8. CR #24~ CR #27: means analog input voltage or current when conversion value from analog
signal to digital is 4000. Voltage setting range: -4V~+20V(-3200
LSB
~+16000

Normal run: POWER LED should be lit and ERROR LED should turn off. When power
supply is lower than 19.5V, ERROR LED will blink continuously till the power supply goes
higher than 19.5V.
3. When it connects 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 instruction during controlling by RS-485, A/D LED or D/A
LED should blink.
5. After converting, ERROR LED should blink if input or output exceeds upper bound or lower
than lower bound.

Refer to following for detail.
ES series model doesn’t support pulse
execution instruction (FROMP, DFROMP).
Command
Explanation
In ES series models, flag M1083 is not provided. When FROM/TO instruction is
executed, all interrupts (including external or internal interrupt subroutines) will be
disabled. All interrupts will be executed after completing FROM/TO instruction.
Besides, FROM/TO instruction also can be executed in the interrupt subroutine.
The function of the flag M1083 (FROM/TO mode exchange) provided in EP/EH
series models:
a.
When M1083=Off, all interrupts (including external or internal interrupt
subroutines) will be disabled when FROM/TO instruction is executed. The
Interrupts will resumed after FROM/TO instruction complete. Please be
advised FROM/TO instruction can be executed in the interrupt subroutine.
When M1083=On, if an interrupt enable occurs while FROM/TO
instruction are executing, the interrupt FROM/TO instruction will be
blocked till the requested interrupt finish. Unlike M1080 off situation,
FROM/TO instruction cannot be executed in the interrupt subroutine.

32-bit command when n=3

LSB
) and GAIN value of CH2 to 18 mA

)
: the number for special module.
: the number of CR (Control Register) of
special module that will be read.
: the location to save reading data.
: the
data number of reading one time.
DVP-series PLC uses this instruction to read CR data of special module.
: When assigning bit operand, K1~K4 are used for 16-bit and K5~K8 are used
for 32-bit.
Please refer the footnote below for the calculation of special module number.
To read the content of CR#24 of special module#0 to D0 of PLC and to read the
content of CR#25 of special module#0 to D1 of PLC. It can read 2 data in one time
(n=2).
