How does it work?
DataNet OPC provides an easy and inexpensive way to display real-time industrial data on a live Web page with absolutely no HTML programming required of its user. To allow flexibility and to fit within the existing infrastructure, DataNet OPC can be installed as a standalone Web server or as an Internet Information Services (IIS) add-on.
DataNet OPC Web Page
The DataNet OPC software package makes industrial data more accessible and more useful to those who need it to make important decisions. It allows the user to monitor operational facilities by displaying real-time data. It also keeps a log of stored data files, which are available as downloads for historical purposes. The DataNet OPC Web page is capable of displaying and logging an unlimited amount of data from an unlimited number of devices.
Sample screen: DataNet OPC displays industrial data conveniently on a Web page like this one. Dynamic
colors allow the user to quickly determine whether or not plant operations are running normally.
To enable convenient and easy remote configuration, a configuration facility is provided within the DataNet OPC Web page. This enables the user to configure the page's display and data-logging options from anywhere the Web is accessible.
Sample screen: The DataNet OPC configuration page can be accessed
with the click of a button, from the main data-presentation page.
Configuring the DataNet OPC Web page is quick and easy. No HTML programming knowledge is required of the user. A security feature is included, which prevents any unauthorized changes to the configuration by forcing the user to supply a password in order to access the configuration facility.
Sample screen: The DataNet OPC main configuration page allows the user to control the
Web page's display and data-logging options from anywhere the Web page is accessible. A title
can be added to the DataNet OPC Web page, as well as to each individual row of data.
DataNet OPC displays data in an easy-to-read table format. By editing the column configurations, the user can change the table's appearance by creating a label, or by specifying the width, number of decimals and alignment of the chosen column.
Sample screen: The DataNet OPC column configuration page allows the user to control the Web page's appearance.
By editing the page's row configurations, the DataNet OPC user can change the source of the data that is to be displayed by editing the OPC server and tags. Functional features, such as dynamic color display and a math tool, also are accessible through the row configuration facility.
Sample screen: The DataNet OPC row configuration page allows the user to control the data which is being displayed.
DataNet OPC Server
The DataNet OPC software package includes a Server application that runs as a Microsoft Windows service. The Server communicates with an OPC server to collect raw industrial data. DataNet OPC then translates the data into useable information, displaying it conveniently on a Web page. The DataNet OPC service runs on its own whether or not anyone is logged-in on the Server PC. The user does not need to be present to manually start the program each time the computer is restarted.
Sample screen: DataNet OPC is equipped with an easy-to-use graphical interface, which can be
used to start, stop or pause its services. It also provides a very simple way to install and uninstall the
service. This DataNet OPC Server screen shows the status of the service.
