The Danfoss ECL OPC Server is an OPC serves data to OPC clients. The OPC server was implemented using advanced programming concepts of the current version of the OPC generation industrial software applications.

The OPC Server communicates with OPC clients and real time Danfoss ECL devices. This OPC server is also based on the popular Modbus protocol and can be connected to real world Modbus compatible I/O hardware.

Key features of the OPC Server include:

•

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

Configuration module:

The that holds configurati name, the ranging, and the alarm settings.

The actual values of the tags configured. Structures of both databases are indicated in the following secti

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

OLE™ for Process Control (OPC) is a standards-based approach for connecting data sources (e.g., PLCs, controllers, I/O devices, databases, etc.) with HMI client applications (graphics, trending, alarming, etc.).

It enhances the interface between client and server applications by providing a universally documented mechanism to communicate data from a data source to any client application.

Included are not only a detailed guide on how to pass the data, but also specific information on other attributes to supplement those data, such as range information, data type, quality flags, and date and time information.

Figure 1.1 shows the OPC Architecture, which was introduced by the OPC Foundation. By following the OPC Architecture, a device needs only one standard driver, which is an OPC compl then be connected to that device, either locally or over a network. Furthermore, connections can be made to more than one OPC server at the same time.
