Bringing Together Different Protocols and Systems 

The OPC standards have been a key part of data integration in the Industrial Automation space since 1995 but when you say "my software uses OPC" there's more to it than that because of the many problems OPC solves. Add IoT solutions involving MQTT, Azure, Amazon, Google, JSON data, SparkplugB, and others, and your business' thirst for answers from your data.

The DataHub OPC Gateway and IoT Gateway Packs make it easy to integrate different OPC and IoT Standards 

Smart MQTT Sparkplug Integration with OPC Sources/Destinations & More

DataHub provides smart MQTT client &  broker functionality with Sparkplug support that is tightly and automatically integrated with OPC interfaces so that once you bring data into DataHub, from any source, it can be used with MQTT.

The smart capabilities overcome the many important details involved in using MQTT in industrial control and SCADA applications, especially in larger systems with multiple SCADA nodes, device types and more.  Sparkplug support automatically creates DataHub tags from Sparkplug topics and the data they provide, without any complicated parsing required. 

With V11, Sparkplug, SparkplugB, and Sparkplug 3 are supported, along with adding MQTT V5 support!

Using Streaming Event Data DataHub

DataHub Event stream services support real-time ingestion, distribution, and processing of events or messages from various sources to multiple consumers, facilitating data integration, event-driven architecture, and real-time analytics. Starting with DataHub V11 and higher, Event Streams from Apache Kafka and Azure Event Hubs are available as a data sources.

DataHub External Historian connectors support streaming event data to Apache Kafka and Azure Event Hubs.

Integrating OPC natively with other standards

Where some solutions require you to buy multiple standalone products and connect them together yourself, or do extra steps to make data available to other standards like MQTT, once you connect DataHub to an OPC data source, the data is just that, data, and it's automatically available to the full DataHub feature set. 

• OPC UA Standards
  • Data Access Client & Server
  • Alarm & Conditions Client & Server
  • Historical 
  • OPC UA connection wizard 
  • OPC UA Certificate Manager
  • OPC UA Discovery Server included
• OPC Classic Standards
  • Data Access (DA) Client & Server
  • Alarm & Events (A&E) Client & Server
  • Historical Data Access (HDA) Client in External Historian options (New in V11!)
  • Convert OPC HDA Classic to OPC UA HDA

Bringing Data Together Your Way

DataHub helps you gather data from multiple sources and present it to client programs as a single, unified data set, in a structure that you define as you build your connections.  A single connection to the DataHub gives you access to data from all connected OPC, MQTT, Excel, Modbus, DDE and TCP sources, but also data from Historians and ODBC databases and data entered through web interfaces

Aggregating data brings several benefits

• Reduce load on data sources when multiple clients need the same data 
• Protect control networks and data sources by controlling data collection rates in the DataHub vs from the clients (Case study)
• Some client applications require licenses for each data source you connect to - make DataHub that one data source and reduce your licensing costs for other applications. 
• Combine data from different sources into namespaces/folders that group data by system, site, etc vs source

Assuring Data Availability at Multiple Levels

• Data Source Redundancy for OPC UA, DA, A&E, UA A&C, MQTT and More
• Native OPC UA data source redundancy that preserves hierarchy and namespace, a DataHub exclusive!
• Variety of architectures supported from simple to complex, including proxy and DMZ friendly secure data tunneling redundancy 
• Redundant Data Hub Instances in a high-availability pair supported
• Multi-client redundant architectures supported 
• Flexible trigger conditions

Example Architecture below for redundant OPC Data Sources. Many other architectures possible, more than we can show, so contact us to discuss your needs. 

Get Data Where You Need It, Securely

DataHub tunneling moves any data that you can get into the product, between sites, locations, even without opening firewall ports on control and business networks, working with proxies and DMZs. 

• Connect OPC clients & servers over networks, without DCOM
• Move any data over the tunnel, not just OPC 
• Control whether tunnel endpoints are read-only or read-write
• Define level of security required for each tunnel connection
• Data Diode Mode (New in V11!) enhances security and supports working with hardware data diodes supporting TCP emulation
• Tunnel just the data, not OPC commands, for high performance and resilience
• Automatically resume connectivity when networks come back, unlike DCOM! 
• Know the network is down through data quality indicators 
• Single user configurable TCP port connections, encrypted and password protected 
• Tunnel OPC, MQTT, Modbus, Excel, Database data and more

Data Bridging - Connecting Different Systems, Standards, Technologies

Because all data becomes "just data" once in DataHub, in the namespaces/hierarchy that you setup, you can then use DataHub's Bridging feature to move data between any systems. 

• Create connections between any DataHub points, not just OPC between OPC servers
• Integrate data between different PLC/control hardware 
• Bridge and tunnel using the DataHub tunneling feature, to connect systems across networks, without using DCOM
• Bridge between multiple data sources
• Point-and-click user interface
• Linear & Scriptable transformations
• Multi-threaded, so any one external system that goes offline doesn't necessarily slow down bridges between active systems
• By adding the Modbus TCP option to your DataHub license, you can directly connect to Modbus Ethernet (TCP) data sources and bridge them to OPC UA and other destinations. 

Integrate with Databases and Historians

Just like OPC data, data from databases and historians is data that can be used in the DataHub. Tunneled, scripted, bridged, and more. Store & forward capabilities built-in. DataHub can also write to a wide variety of Historians both premise and cloud hosted as shown below. 

Databases

Cogent DataHub Service for Azure

Securely integrating production data with Azure has never been easier than with the Cogent DataHub Service for Azure. Although you've always been able to license a DataHub instance and run it in an Azure Virtual Server instance, it's likely that is not very cost effective.  The Microsoft Azure Managed Service complements and works with your premise hosted DataHub instances and in a pricing model that is consistent with other Azure applications. An optimized version of DataHub can be used as a service in your Azure account to receive data from local/premise hosted DataHub instances for IT/OT integration, centralized historians, cloud historian and SCADA integration, analytics, AI and more.  Integrate with the over 3,000 Azure partner apps.

Secure Data Relay in the Cloud 

The Cogent DataHub Service for Azure provides a secure cloud relay or proxy for streaming your data that doesn't require any open inbound firewall ports on either side of the connection for Secure IT to OT or Plant or Interplant Networking or Remote Monitoring

Connecting Modbus TCP Devices

Modbus, the well known, pervasive communications protocol found in thousands of control devices, can be directly integrated into DataHub.

The DataHub Modbus TCP feature is available with an OPC DA or UA server interface, or can be added on to any other DataHub product pack.

Other applications include Modbus to MQTT conversion, Modbus datalogging, Secure encrypted Modbus data tunneling, Modbus to Excel integration and more. 

Securely Move Excel Data Anywhere

Microsoft Excel is known by everyone as a tool for data analysis, and nearly everyone has it on their work computer. 

But getting data from your control system into Excel in something other than a CSV export file isn't fun. Sure you can use DDE, and DataHub can use DDE to connect any data to Excel.  DDE is a legacy technology which is why we came up with a better way.

The DataHub Vine Plug-In is a native Excel add-in that brings real-time and bi-directional data sharing to your spreadsheets. 

• Connect any worksheet to DataHub and see live updates
• Data refreshed when spreadsheet opened next
• Share Excel analysis results back to DataHub and on to your control systems
• Integrate Excel with OPC & Modbus 
• Send Email notifications from DataHub based on changes in the Excel worksheet

Free Configuration & Monitoring Tools & Extensive Security

DataHub configuration tools are included free with every DataHub Solutions Pack and are built into the application.

• Local configuration
• Secure Remote Configuration 
• Configuration Import
• Data Monitoring
• Event Monitoring/Logging
• Connection Viewer & Diagnostics 

Security is built into all DataHub systems and provides the means to control who connects to interfaces, who can configure the DataHub, and more. 

DataHub's secure data tunneling capability that is firewall, DMZ, & proxy friendly and supports configurations that can even move any data you can get into DataHub without open firewall ports is a key differentiating strength. 

With V11 and higher, you can integrate with ActiveDirectory via LDAP to delegate authentication to your domain.  MFA is added for user login for configuration or Webview. Filtering of data sources by IP, IP range, and protocol are also added and last but not least, V11 also adds Data Diode mode in the DataHub secure tunneling capability.
