An often important task when logging important process data to a database or even to the cloud is verification that the data has been logged. This ensures that data has been successfully logged and will not be lost when overwritten in the downstream process.

In this video blog, we'll step through the configuration required in the OPC Data Logger for logging important process data to a database on condition related to a monitored item and how to perform a writeback to the OPC data source confirming the data has been successfully logged.

With the advent of cloud-based solutions in every industry, it's only natural that you might need to migrate from a traditional locally-hosted SQL database for logging your process data to Azure. Fortunately, logging both to traditional SQL and Azure SQL are similar in many ways and OPC Data Logger makes it possible to log to both for OPC UA and DA data sources.

In this video blog, we'll review the basic setup and architecture for OPC Data Logger and then step through the configuration required for logging to SQL and Azure SQL from an OPC server.

TOP Server for AVEVA™, formerly Wonderware provides connectivity to hundreds of device types and protocols, but that's not all.  With the TOP Server OPC Client Suite, it's also possible to use your existing classic OPC DA and OPC XML-DA servers with OPC UA clients.

In this video blog, I'll show you how to make a secure OPC UA connection from OPC UA clients supporting the Data Access profile to TOP Server for integrating process data from OPC DA Classic servers using the TOP Server OPC DA Client driver.  I cover the basics of connecting to your OPC DA server and making an OPC UA connection using an OPC UA test client.

As you may already be aware, the Cogent DataHub has a wide range of flexible connectivity options between different data sources such as MQTT, OPC UA, OPC DA, ODBC, DDE and so much more.  MQTT client and broker functionality in particular allow DataHub to integrate MQTT data sources with HMI, SCADA, MES, historian and other systems that don't natively support MQTT.

In this next installment of our Cogent DataHub Virtual Training series, we will cover step-by-step how to easily connect 3rd party MQTT clients to the DataHub MQTT broker and convert their data for access by your own systems with OPC UA or OPC DA client capabilities.

Access to various industrial data via RESTful web services is increasingly becoming necessary in this era of inter-connectivity and big data. From sources such as devices with self-hosted web services to relevant market data such as weather information and pricing for commodities and energy, there is a host of relevant data to be integrated from such RESTful web services.

In this video training blog post, we will cover step-by-step how to easily connect to and consume data from RESTful web services and then push that data to OPC and SQL systems with the OPC Router.

Cogent DataHub is always expanding its wide range of flexible connectivity options between different data sources such as MQTT, OPC UA, OPC DA, ODBC, DDE and so much more.  With the advent of IIoT and its increasing adoption across industries, connectivity to various traditionally non-IIOT data sources via MQTT is key.

If you're not familiar with the concept of a virtual or digital twin, it's the idea of virtual modeling a physical asset or system.  Ultimately, the key motivators for creating digital twins is having the ability to accurately model and predict what will happen with the real-world physical equivalent of that digital twin.  Digital twins are extremely beneficial towards predictive analytics used for pro-active maintenance and process optimization across industries.

In this next installment of our Cogent DataHub Virtual Training series, we will cover step-by-step how to easily connect and push data from OPC data sources to digital twins in the Azure IoT Hub including how to optionally do so through a network DMZ (DeMilitarized Zone) using an additional DataHub as a proxy server for even greater security.

While TOP Server for AVEVA™, formerly Wonderware provides connectivity to hundreds of device types and protocols, that is only part of how TOP Server helps with integrating industrial process data with external software such as AVEVA™ System Platform, formerly Wonderware and other client applications.

You're likely aware that TOP Server is an OPC UA server.  But TOP Server can also act as an OPC UA client for integrating with other OPC UA servers, as well.  For situations where you have a UA server to integrate but your client does not support OPC UA, but does support one of TOP Server's other client interfaces, TOP Server can be the gateway solution. This is especially valuable for AVEVA users who wish to keep using AVEVA Suitelink, OPC DA, or have not migrated to a version of AVEVA applications that support OPC UA Client functionality. 

In this video blog, I'll show you how to make a secure OPC UA connection from TOP Server to other OPC UA servers supporting the Data Access profile.  We cover the basics of configuring the OPC UA Client driver in TOP Server and making an OPC UA connection to another OPC UA server.

Cogent DataHub enables a wide range of flexible connectivity options between interfaces for different data sources such as OPC UA, MQTT, OPC DA, ODBC, DDE and so much more.  This is why we commonly refer to DataHub as a "gateway", as it is frequently utilized for data integration by external software such as HMI, SCADA, MES, historians and other client applications, including for IIoT integration.

In Part 1 of our Cogent DataHub Virtual Training series, we will cover step-by-step how to easily connect OPC UA (Data Access Profile) client applications to your OPC DA Classic server data sources.
