DVP04TC-S

1 WARNING

Always read this instruction thoroughly before using the DVP04TC-S.

Make sure that power is OFF before wiring.

This is an OPEN TYPE PLC. The PLC should be kept in an enclosure away from airborne dust,

humidity, electric shock risk and vibration. Also, it is equipped with protective methods such as

some special tools or keys to open the enclosure, in order to prevent hazard to users or damage

the PLC.

Do NOT connect the AC main circuit power supply to any of the input/output terminals, or it may

damage the PLC. Check all the wiring prior to power up.

Do NOT touch internal circuit within 1 minute after power is OFF.

Make sure that the DVP04TC-S is properly grounded , to avoid any electromagnetic noise.

2 INTRODUCTION

2.1 Model 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). The DVP04TC-S series can read/write the data by using

instructions FROM / TO via DVP-PLC SS/SA/SX/SC MPU program. There are 49 CR (Control

 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.

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 can be set individually. For example, If you want to set

CH1~CH4 as following: 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 times of input readings 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 from

multiple temperature readings. Example: If CR#2 is 10, the temperature in CR#6 will be the

average of the last 10 readings in CH1.

5. CR#10 ~ CR#13: The average temperature (°F). The average temperature is calculated from

multiple temperature readings. Example: If CR#2 is 10, the temperature in CR#12 will be the

average of the last 10 readings in 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 DVP04TC-S – OFFSET value.
