Description
DECS 2.0
DECS 2.0 |
The Danfoss Energy Control System (DECS) is a |
|
web-based SCADA software solution (Supervisory |
|
Control And Data Acquisition) for district heating |
|
systems. |
|
This SCADA solution is typically installed locally |
|
at the heating utility and will automatically |
|
configure its user interface and functionality to |
|
support the application in the controller (for |
|
example Danfoss ECL Comfort 310). |
The user of the DECS 2.0 system is able to remote control and monitor the parameters settings in the controllers and also monitor actual, reference and historical values of sensors and meters connected to the controller.
Danfoss ECL Comfort 310, OPR0010 and OPR0020 controllers are supported by the autoconfiguration features of DECS 2.0, but the ECL Apex 20 controller can also be supported by manually adding graphics and programs into DECS 2.0.

User benefits |
The advantages of DECS 2.0 are among others: |
|
Easy installation |
|
Automatic configuration makes installation easy |
|
Advanced techniques are used for simplifying and |
|
automating the installation process. Once the |
|
controller is installed and connected to the |
|
network, the web-based user interface is |
|
generated on the DECS server with just a few |
|
mouse clicks. The DECS server software is installed |
|
at the heating plant and has no special |
|
requirements except for a reliable PC connected |
|
to the internet. |
|
Easy customization |
|
User interface and functionality suits project specific |
|
needs |
|
DECS is a visualisation platform based on the |
|
Atvise SCADA system. The user interface and |
|
functionality is easily customized by the system |
|
integrator to project specific requirements using |
|
the Engineering Tool. The scaleability of DECS |
|
ensures an optimized SCADA solution for small, |
|
large and growing district energy networks. |
System architecture |
The architecture of DECS 2.0 is shown below. |
|
The central building blocks of the DECS 2.0 system |
|
are the HMI (Human Machine Interface) using the |
|
Atvise SCADA Client software from Certec, the |
|
database for storing all logged data from the |
|
controllers and the OPC UA Server software |
|
handling the data communication with the |
|
controllers. |
Easy access
Access to control and monitor locally and remotely
Data is constantly exchanged between the controllers and the DECS Server. The server provides an intuitive user interface, which is accessible from any standard browser on a PC, laptop or smartphone connected to the internet. You can control and monitor your heating station and substation installations from everywhere.
Standard
System is built on standardized software and interfaces
Standardized DECS Server software increases reliability, lowers hardware complexity and allows integration of other building automation systems into the heating system. The communication interfaces are based on the well-known ModbusRTU or Modbus-TCP protocols, which provide a reliable, low complexity network.
DECS 2.0 supports data communication between the server and controllers using Modbus-TCP (Ethernet), LON bus and Modbus-RS485.

DECS 2.0 Danfoss Energy Control System |
Application |
DECS 2.0 software automatically adapts its user |
|
interface to fit the application in the controller. |
|
The following controller applications are |
|
supported: |
|
• ECL Comfort 310 controller |
|
* Please see ‘List of application keys |
|
supported by DECS 2.0’ |
|
Go to http://heating.danfoss.com. In the |
|
‘Documentation’ menu select ‘Electronic |
|
Controllers & PI Controllers > SCADA |
|
Solutions > Data sheet’. |
|
• OPR0020 Controller |
|
* Firmware R4 and newer |
As an option the ECL Apex 20 controller can be integrated into DECS 2.0 to remote control and monitor the district heating utility or boiler house.
This requires a system integrator to develop a customized application for the ECL Apex 20 controller as well as a customized HMI for the DECS 2.0 system using the OPC server software for ECL Apex 20.
•OPR0010 Controller
*Firmware v3.
Below is an application example of DECS 2.0 in a biomass district heating network using Modbus-RS485 for data communication. The server, which has DECS 2.0 installed, is located in the district heating utility and a central laptop is used for operating the DECS 2.0 system.
An external service provider also has access to the DECS 2.0 system using his laptop connected to the internet. The server and the ECL Comfort 310 controllers are communicating via an RS485 serial link using the Modbus protocol.

DECS 2.0 Danfoss Energy Control System |
Application |
Below is an application example of DECS 2.0 in |
|
biomass district heating network using Modbus- |
|
TCP (ethernet) for data communication. It is similar |
|
to the previous example except that the ECL |
|
Comfort 310 controllers are communicating with |
|
the server via standard internet connections using |
|
the Modbus protocol. |
These internet connections may be used also by laptops in the houses for browsing the internet and also to access the DECS 2.0 system.
