DataHub® Features and Options
The Cogent DataHub has many different features that let you connect to many different sources of information, integrate the data, and use it as you need to. This section of the web site explains each feature. You can choose from the Product Packs that bundle different features together or Contact us to create a custom pack.
OPC DA Support
Cogent is a long-time member of the OPC Foundation and has delivered products that support this industry standard interface for many years. See OPC DA for more details. Cogent DataHub will connect to OPC DA 3.0 servers (and 2.05a servers that support browsing) and will also accept connections from OPC DA 3.0 or 2.05a clients. OPC Aggregation is performed as a natural behavior within the DataHub. Connect to multiple OPC DA servers and you can store the data in a common data set within the DataHub, while maintaining an internal separation to effectively partition the incoming data.
OPC Alarm and Events
The OPC A&E support within the Cogent DataHub allows it to act as an aggregator and tunneller for alarms and events. See OPC A&E for more details. The DataHub doesn't generate the alarms and events itself; it reads them from installed OPC A&E servers. The DataHub acts as an A&E client program to bring data into the DataHub, where it can be used by any other DataHub client program. The DataHub can also act as an A&E server to offer the aggregated data to an A&E client program. The DataHub can tunnel the A&E data and make it available to A&E clients on remote network computers.
Cogent software has supported the Microsoft DDE interface since the beginning. As the standard for communication between Microsoft Office products, it makes perfect sense for the DataHub to support this protocol. See DDE/Excel Support for more details.
Network System Monitor
DataHub System Monitor is a smart idea well executed. Each DataHub on your network has the ability to query the operating system it is running on for system status and resource capacity. This data can be sent back to a central location, where system wide monitoring of critical network resources can help identify problems before they start, or alert support staff when things do go wrong. See System Monitor for more details.
For customers with highly customized systems, or where standard data interfaces are not available, the DataHub offers .NET, JAVA and C++ application programming interfaces (APIs). See DataHub API for more details.
Unique to the middleware market is the DataHub's ability to mirror data between Microsoft Windows systems and many types of QNX and Linux platforms. Many customers have used the multi-platform support to build systems that fully integrate cross-platform real-time data mirroring. See Non-Windows OS for more details.
Embedded Data Access
The DataHub offers a tremendous opportunity to developers of embedded systems. A zero unit cost solution allows the developer to offer a complete range of integration solutions which use embedded data as the driving force behind web visualization, database interaction or email notification. See Non-Windows OS for more details.
A common problem that many customers face is the need to associate data points in one system with corresponding data points in another system. The Cogent DataHub makes this easy by providing an intuitive data bridging interface that allows you to define this point to point mapping, along with linear transformations that can be applied to the data as it passes from one system to another. Think of the situation where you have a temperature in °F on one system and you want to map it to a system that is using °C. Bridging makes this easy. See Data Bridging for more details.
More than just tunnelling to overcome DCOM problems, the Tunnel/Mirror feature enables full data mirroring over a network, so that client-side applications can continue to work with the most recent data should the connection to the server become unavailable. Unique among the OPC Tunnelling products on the market, this feature is at the core of many of our real-time data integration solutions. See Tunnelling for more details.
The Security serves two primary purposes: authentication and authorization. Authentication limits access to recognized users, based on a username/password combination. Authorization provides a set of permissions for each user, allowing access to certain functions while denying access to others. See Security for more details.
One of the most acclaimed features of the DataHub products has always been its powerful built-in scripting language. Capable of doing everything from writing data to CSV files, to running full control strategies on a process-wide basis. The DataHub scripting language is what allows the customer to fully meet their system requirements when off-the-shelf programs leave them stuck trying to finish the project. See DataHub Scripting for more details.
Data Source Redundancy
After careful examination of the needs of our customers, we set about building the best data redundancy mechanism on the market today. The results are proven in the instantaneous fail-over response of the new Data Redundancy feature within the DataHub. See Data Redundancy for more details.
The Cogent DataHub makes it easy to aggregate data from multiple different data sources, using different protocols. This has many advantages, from reducing client applicaton licensing fees to producing plant wide common data sets to enable effective control. See Data Aggregation for more details.
MES and ERP Connectivity
Integrating factory and management execution systems (MES) has been a long standing feature of the DataHub. With its ability to read and write data to ODBC databases, its OPC and DDE direct connections and the ability to use APIs to customize an interface, the DataHub is able to not only make the necessary data connection, but can also do so securely, so that critical data on both sides is not exposed to corruption. See MES Connectivity for more details
The DataHub WebView feature is the flagship new addition to Cogent DataHub v7. Cogent has been offering real-time web display capability for many years, but nothing as powerful and easy to use as this new Silverlight based development and display environment. Collaborative screen development and full permissions-based access means a new way of working with real-time data on the web without knowing anything about web development. See DataHub WebView for more details.
DataHub QuickTrend -Real-time Trend
When Cogent started working on the new DataHub QuickTrend feature we soon realized this was too good to keep to ourselves. So we decided to offer this real-time trending feature as a standalone free download available here. Easily connect to data from both OPC and DDE servers to produce powerful real-time trend displays that can be scrolled and zoomed to fully analyze the inner workings of your factory, embedded system or financial strategy. See DataHub QuickTrend for more details.
Cogent DataHub's Data Logging feature is one of the most popular with our current customers. It enables both reading and writing of data with any ODBC compliant database (nearly all Windows and Linux based databases are ODBC compliant). Combining both a powerful, yet easy to use configuration interface, with the ability to use DataHub scripting to completely customize the read/write procedure, the Data Logging feature makes it easy to fully integrate real-time process data into management and archival systems. See Data Logging for more details.
One of the new features in Cogent DataHub v7 is the Data Historian. This is a high speed, high volume historian specially designed to provide historical data for both QuickTrend and WebView trend displays. See Data Historian for more details.
DataHub products have a reputation for ease of use and this is true of the Email notification feature. A clean, smart interface makes it easy for you to configure multiple email and SMS actions based on simple triggers or complex alarm strategies. See Email/SMS Notification for more details.
Networking Excel data
Microsoft application data can be shared across a network using the Cogent DataHub. See DDE/Excel for more information
Serve data to the Web using the DataHub WebServer. The WebServer supports ASP, AJAX and Java Applets. See WebServer for more information. Using the WebServer does require some knowledge of html or Java applets. If you are looking to serve data to the Web without any programming you should use the DataHub WebView.
