OPC Server The Danfoss ECL Comfort OPC Server is an OPC-

compliant server that serves data to OPC clients. The OPC server is implemented using advanced programming concepts of the current version of the OPC speciﬁcation for use in developing modern industrial software applications.

The OPC Server communicates with OPC clients and Danfoss ECL Comfort controllers. This OPC server is also based on the popular Modbus protocol and can be connected to real world Modbus compatible I/O hardware using Modbus via an RS485 serial line or Modbus via a TCP/IP Ethernet/internet connection.

Key features

• Advanced OPC data quality and data conversion to client’s request.

• Supports multiple multi-drop I/O devices.

• User interface for viewing tags, groups, and real-time signals.

• OPC data spy is included for viewing real-time signals in OPC Client and OPC Server Conﬁguration module.

• No limits to number of connections, subscriptions or tags.

• OPC tags for server status: checking, detection of connection problems and server failures, performance etc.

• Multiple independent OPC server connections.

• Performance data throughput on serial connection @ 38400 baud: 15 packages/sec.

• Compressed read of device parameters.

• Read heat meters basic data using M-bus network in ECL Comfort 310.

• M-bus gateway function.

• Read data log ﬁle from ECL Comfort 310 memory.

• ECL Alarms in OPC tags.

• Customer basic data as OPC tags.

Data sheet ECL Comfort OPC Server

The OPC Server software contains two parts: a user interface conﬁguration module and the actual OPC server, the runtime module.

Conﬁguration module The conﬁguration module allows you to create a

database that holds conﬁguration data of the tags such as the tag name, the data type and the alarm settings.

Runtime module The runtime module uses a runtime database to

access the actual values of the tags conﬁgured. Structures of both databases are indicated in the following sections.

User beneﬁts The advantages of the OPC Server software are among others:

Easy installation Easy modiﬁcations

The wizard makes installation easy

The installation of the OPC Server software is made easy with the installation wizard. It installs both the Conﬁguration module as well as the Runtime module. After installation you are immediately able to integrate the ECL Comfort controller into the SCADA system. The OPC Server can even be combined with other OPC Servers.

The special features are: Intelligent OPC Group parameter optimization. Automatically adds, removes and maintains OPC groups and items from ECL 210 / 310 controllers. Simulation of OPC tags. Set up alarm conditions for OPC tags. Conversion of OPC server database based on ECL Comfort 300 / ECA71 interface.

Changes made to the conﬁguration are accepted only after a restart of the OPC server. However, changes made to the runtime database are accepted online.

The SCADA system can easily be extended or modiﬁed

New ECL Comfort controllers can easily be added to the SCADA system at any time by using the Conﬁguration module. From here you can create new areas and groups and assign ECL Comfort controllers to these groups with just a few mouse clicks. Switching to new application keys is also made easy by using the Conﬁguration module as all parameters (PNUs) for the available application keys are predeﬁned.

Easy conﬁguration Optimized performance

Use the Conﬁguration module to save time

The Conﬁguration module is a part of the OPC Server software package. It is a valuable tool to ease the integration of an electronic device, like the ECL Comfort controller, into the SCADA system. With the Conﬁguration module you can let the SCADA system use all the predeﬁned parameters (PNUs) for a speciﬁc application key with just a few mouse clicks. The engineering units, signal ranges and data types for the parameters can be modiﬁed if needed.

The OPC Server ensures optimal reading of parameters

The OPC Server has implemented special methods to optimize the performance of reading parameter values in the ECL Comfort controller. This ensures high performance of the SCADA system even when many parameters need to be read from many ECL Comfort controllers.
