WARNING
Always read this manual thoroughly before using the DVP04TC-S.
In order to avoid electric shock, do not touch the terminals or conduct any maintenance while power is
applied to the PLC. Never open the PLC. Only qualified Delta personell should conduct any internal
electrical work on the PLC.
This is an OPEN-TYPE device and must be placed in an environment away from high temperatures, high
humidity, exceessive vibration, corrosive gases, liquids, airborne dust, and metallic particles when installed
in an enclosure.
Do not apply AC power to any of the input/output terminals, this will cause permanent damage to the
DVP04TC-S. Do NOT touch terminals when power on.
Make sure that the DVP-04TC is properly grounded , to avoid any electromagnetic noise.

INTRODUCTION
2.1Model Explanation and Peripherals
Thank you for choosing DELTA’s DVP Series PLC. The DVP04TC-S allows the connection of four
thermocouple sensors (Type J.K.R.S.T). The DVP04TC-S series can read/write the data by using commands
FROM / TO via DVP-PLC SS/SA/SX/SC MPU program. There are 49 CR (Control Register) in each module
and 16 bits per register.
DVP04TC-S thermocouple sensor can update software version by RS-485. Power supply and main
processing units are sold separately.
The DVP04TC-S works with both Centigrade and Fahrenheit. The input resolution for Centigrade is 0.1
degrees and for Fahrenheit is 0.18 degrees.

Explanation:
1. CR#0: The PLC model type.
2. CR#1: Used to set the working mode of four channels (CH1~CH4). There are 2 modes (J-type and K-type)
for each channel and allow to set separately. For example, If you want to set CH1~CH4 as CH1: mode 0
(b2~b0=000), CH2: mode 1(b5~b3=001), CH3: mode 0(b8~b6=000) and CH4: mode 1(b11~b9=001), you
should set CR#1 to H0208. The higher bits (b12~b15) will be reserved and the factory setting is H0000.
3. CR#2 ~ CR#5: Used to set the number of input readings used for the average temperature calculation. The
available range is K1~K4096 and factory setting is K10. (Note: When PLC sets average times via TO/DTO
instructions, please use rising-edge/falling-edge detection instruction (such as LDP and LDF) to get correct
average times.)
4. CR#6 ~ CR#9: The average temperature (°C). The average temperature is calculated using 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#13: The average temperature (°C). The average temperature is calculated using multiple
temperature readings. Example: If CR#2 is 10, the temperature in CR#12 will be the average of the last
10 readings on CH1.
6. CR#14 ~ CR#17: display present temperature (°C) of CH1~CH4 input signal.
7. CR#18, CR#23, CR#28, CR#29 are reserved.
8. CR#19 ~ CR#22: display present temperature (°F) of CH1~CH4 input signal.
9. CR #24 ~ CR #27: display offset value of channels CH1~CH4. The range is -1000~+1000 and unit is 0.1
degrees C. The definition of OFFSET is Actual temperature = temperature measured by DVP-04TC –
OFFSET value.
10. CR#30 is a fault code register. Refer to the following chart.

Note: Each fault code will have corresponding bit (b0~b7). Two or more faults may happen at the same time. 0
means normal and 1 means fault occurs.
11. CR#31: RS-485 communication address. Setting range is 01~255 and factory setting is K1.
12. CR#32: RS-485 communication baud rate: 4800, 9600, 19200, 38400, 57600 and 115200. b0:4800bps,

even, 1 stop bit (8 E 1).
13. CR#33: Used to reset the settings of CR registers to factory defaults.
14. CR#34: software version.
15. CR#35~ CR#48: Reserved for internal system use.
16. The corresponding parameters address H 4096~H 40C7 of CR#0~CR#48 may provide users to read/write
data via RS-485 communication.
a) Communication baud rate: 4800, 9600, 19200, 38400, 57600, 115200 bps.

INITIAL PLC START-UP
LED 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. DVP04TC-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.
Example:
M1000
FROM K0
= H8B D0
TO K0
FROM K0
FROM K0
FROM K0
FROM K0
END

Explanation:
Reading the model type of expansion module K0 (should be H8B for DVP04TC-S model type).
The averaging number for CH1~CH4 will be D10~D13.
If the model type is DVP04TC-S. Reading the average temperature (°C) of CH1~CH4 (4 data) from

3. In PB models, flag M1083 is not provided. When the FROM/TO instruction is executed, all interrupts (including
external or internal interrupt subroutines) will be disabled. All interrupts will be executed after the FROM/TO
instruction is completed. The, FROM/TO instruction can also be executed in an interrupt subroutine.
4. The function of the flag M1083 (FROM/TO mode) provided in PC/PA/PH models:
a. When M1083=OFF, FROM/TO instruction is executed, all interrupts (including external or internal
interrupt subroutines) will be disabled. All interrupts will be executed after FROM/TO instruction is
completed.
b. When M1083=ON, if an interrupt occurs while the FROM/TO instruction has been programmed, The
FROM/TO instruction will be interrupted to execute the interrupt. The FROM/TO instruction cannot be
executed in the interrupt subroutine.
