Trying to complete our communication library, today we will show you how to communicate some HMI with our 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
7 Data Bits
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.

I would like to notify you that almost all your links are dead (page not exists) or not working (cannot connect to the target). Seems that they have been made long time ago and most of them are not actual.

how i can read the temprature and transmitt it to a delta hmi to show??
March 15, 2018 at 6:09 pm
I am planning to design a delta hmi with inbuilt plc for pasterizer bath,is it possible to achieve PID control without using delta temperature controllers and to set actual temperature and set temperature on the programme

plz tell me how i can communicate or programmed multiple DTC 1000 modules to one dop- b series hmi. I understood the programming of one DTC to HMI.
but it’s difficult to more DTC’ s.

Sir I want to communicate between yudian temperature controller model AI 526 and delta dop b07 hmi.
Pls provide me details for communication

i want to control a temperature of a furnace where modulating gas valve is installed.(2 control outputs required)
should i used DTC1000 or it can be controlled through PLC+PT100 Module?
if it can be controlled through PLC then can i have a little bit hint.

i need some information regarding Delta HMI to any RTU modbus device programming configuration.
i want to know what is a simplest procedure to display register values of Modbus based device on Delta HMI..
i don’t understand how to configure HMI to read values form other RTU Modbus device.
like Delta HMI and Brainchild 8AII module.

it should not be so complicated.
pls be more simple with your products setting.

How to see the present temperature value on HMI from DTC Delta temperature Controller, please help me

I have a problem with DTB4848RRE series controller.
I am trying to control a gas burner to heat a furnace by ON-OFF control.
After the controller is power on, the contacts of Out1 remain close till the temperature reach the SV.
The contacts close again when the temperature has gone below the SV, and will remain close for 2-3 minutes.
The controller after a while open the contacts of OUT1 and remain at that state till the power is ON. During this condition the value on PV is flashing.
Below you will find the parameters I used for ON-OFF control.
Initial Setting Mode
CnPt = Κ
tP-H = 999
tP-L = -99
CtrL = ON-OFF
S-HC = HEAT
ALA1 = 7
ALA2 = 0
SALA = ALA1
CoSH = on
tPoF = 0.0
HtS = 2.0
r-s = rUn
SP = 1
AL1L = 29
LoC = oFF
PV = …25…
SV = 33
Please, may you tell me what am I doing wrong?

How I conect a red lion counter via modbus with a dvp? If I want to send and read on hmi
October 13, 2011 at 2:41 pm
What kind of protocol this counter uses?
With DVP you are able to create your own protocol, but it’s a hard job…
If this counter accepts Modbus, then use the RS or MODWR instructions.
If it don’t accept Modbus, then look for some Delta CTA ;P
