Temperature Controllers (DTC)

DVP04TC-S/DVP04PT-S & DTE Channel setup

For DVP04TC-s/ DVP04PT-s and DTE its is possible to configure the input channels for different sensor types and also disable the unused channels. This will prevent flashing error LED when no other errors are present.

  • For DVP04TC-s and DVP04PT-S we use Control Register 1 (CR#1):

Example 1: For DVP04TC-S set CH1 for J-type sensor, CH2 K-type sensor, CH3 T-type sensor and disable CH4.

CH1 = (b2-b0) = (0, 0, 0) for J-type

CH2 = (b5-b3) = (0, 0, 1) for K-type

CH3 = (b6-b8) = (1, 0, 0) for T-type

CH4 = (b11-b9) = (1, 1, 1) to disable channel

Example 2: For DVP04PT-S set CH1 for PT100 sensor, CH2 NI100 sensor and disable CH3-4.

CH1 = (b3-b0) = (0, 0, 0, 0) for PT100

CH2 = (b7-b4) = (0, 0, 0, 1) for NI100

CH3 = (b11-b8) = (1, 1, 1, 1) to disable channel

CH4 = (b15-b12) = (1, 1, 1, 1) to disable channel

  • For DTE we use Function Address 10F6H :

Example 3: For DTE set CH1 – CH4 Enable, CH5 -CH7 Disable & CH8 Enable:

CH1(b0) = (0) Enable

CH2(b1) = (0) Enable

CH3(b2) = (0) Enable

CH4(b3) = (0) Enable

CH5(b4) = (1) Disable

CH6(b5) = (1) Disable

CH7(b6) = (1) Disable

CH8(b7) = (0) Enable

Write data 01110000 0r 70H to Function Address 10F6H

Temperature controllers: How to Return to Default settings

The ones of you who deal with Delta temperature controllers, sooner or later found on the situation to reset the Temperature controller to default values.

How to do that without using DTCOM?
Please follow the below instructions if you have a DTA or DTB
untitled
In case you have DTD4848 just change the keys [V] & [SET], for [] & [SET].

But what happen with DTC? This device have no buttons.
So If you change the Modus Address, and you do not remember what address you use… you´re in a trouble.

In this case, you have 2 options:
Or you use the LED code of the manual to guess the protocol and address
qqqqqqq

Or just follow the below instructions to take the DTC back to factory defaults:
1. Switch to “RUN, and Power on the device.
untitled1

2. After 5 seconds, the device should show as below picture.
untitled2

3. Switch to Stop and wait until the RUN LED is off
untitled3

4. Switch to RUN and wait for the RUN LED is on again.

5. Repeat the steps (3) and (4) three times within 60 seconds, and If everything is OK, all led should switch to ON as below picture.

This feature is available starting from Firmware v1.5

In case you’re a communication guy, download the attached manual to reset to factory default all Temperature controllers using out software DTCOM.

Default reset by Communication.

PLC Link (PLC to Temperature Controllers)

Happy new year 2013 for you all.
We decide to start this new ear with a new chapter of the PLC-Link series, I hope you like it!

As we see on the other chapters PLC to PLC and PLC to VFD, PLC Link is a method to easily communicate with Delta devices based on RS485 Modbus.
Because we already did it PLC and VFD, today we´ll do it with Temperature controllers.

1. Netwrok Structure:
Communication is RS485, so follow the twisted pairs recommendations when possible.
untitled

2. DTC Configuration:
First you have to setup the communication protocol as the PLC (9600,7,E,1 ASCII)
Second, remeber to change to 1 the parameter “Communication write-in selection”

untitled

3. PLC Software:
Step 1 -> Set up communication protocol
Step 2 -> Set the number of register to be read/write (Check manual to understand the D1436 and D1452 special register meaning).
Step 4 -> Select the registers to be read/write (H4700 = Present Value; H4701 = Set Value)
Check the following Table for DTA and DTB
untitled
For DTC or DTD jus follow the DTC manual table
Step 5 -> Enable PLC-Link

Do not hesitate to download the below examples
PLC LINK COM2 (PLC – DTC) and PLC LINK COM2 (PLC – DTA).dvp (Tested by DDC Automation)

Special Thanks to DDC Automation from UK for this example

Delta FTP reorganization

Due recently we have been presenting many new models.
And because or FTP has been not organized since 5 years ago.
We decide to update the FTP to make it more user friendly and adding all the new products, with one-link for software packs and many new product images.

Don´t hesitate to take a look!

And for the ones who couldn´t assist, we invite you on the next SPS/IPC/Drive Messe in Nürnberg from 27-29 of November 2012.

Announcement: CTA-D (24Vdc Counter/Tachometer/Timer)

Delta R&D team has launched the new cost-effective and user-friendly industrial automation product, the 3-in-1 timer/counter/tachometer. But this time with 24Vdc power supply.

You can check all the features of this device in the following announcement

Furthermore, If you want more information regarding this device, don´t hesitate to take a look on the CTA website

HMI – DTC

Trying to complete our communication library, today we will show you how to communicate some HMI with our Temperature controllers.

Delta Temperature Controllers

Delta Automation have several models of Temperature controllers, in this case we need the ones with communication feature (almost all of them).
Please refer to the next link for further information.
DTC Delta temperature Controllers

Like all the communication examples, we start fixing the protocol we are going to use. In this case:
RS485 Modbus ASCII
38400 bps
7 Data Bits
Parity Even
1 Stop Bits

So once we have decided the protocol, we have to implement it on both devices.
To implement to the HMI please refer to the HMI- 3 PLC communication example post.

To implement to the DTC please download the next video, where is explained step by step how to configurate some DTC trough Computer.
HMI – DTC control

In case that you already have some DTB or DTA, you can do it following the instruction manual.
DTA Instruction Manual
DTB Instruction Manual

And finally here attached some DOP-B program example for control by communication some DTC (Delta Temperature Controller).
HMI – DTC control Example

And if you need to add some internal register of the DTC, and you can found it on the example, just take a look to the DTC manual, and you will found the Modbus table.
