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.

Firewall Ports: There's More to It and Why Your IT Team Has Concerns

In follow up to my teammate Marc’s post last week around OPC UA and network traffic, this week I’m going to explore firewall ports in more detail. My goal is to help you understand where IT is coming from when they get concerned about any open inbound ports on firewalls. There is more to it than the obvious which is why they ask a lot of questions. This is especially true when one is talking about a connection that is coming from outside the plant firewall, but also even when it’s a port between a business and a production network.

Through understanding more, you’ll be able to have collaborative discussions with your IT team, where you can weigh the risks with IT as your partner, look for options that address the risks, and accomplish the movement of data required to run your business in ways that address your application-specific security concerns.

Tech Support Corner: When Your IT Team Asks about OPC UA and It's Potential Network Impact

3 min read

By Marc Holbach on Oct 1, 2020 2:00:00 PM


The adoption of OPC UA technology continues to grow more with each passing year.  And for good reason.  OPC UA provides a means to encrypt data as it is transferred between client and server that other client interface options simply do not. But when it comes time to have that discussion with your IT department around whether they are going to let you run OPC UA inside the firewall on a network, they likely will have concerns centered around common IT concerns in networks. 

Continuing our Tech Support Corner blog series, this post covers some common concerns that our support engineers have encountered from process engineers collaborating with their IT department about OPC UA client's and servers running on their network and the factors to consider in those discussions.

How to Convert MQTT Client Data to OPC

2 min read

By Win Worrall on Sep 24, 2020 2:00:00 PM


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.

Integrating RESTful Web Services with OPC and SQL

2 min read

By Marc Holbach on Sep 17, 2020 2:00:00 PM

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.

Using MQTT to Stream OPC data to Digital Twins in Azure IoT Hub

3 min read

By Win Worrall on Sep 3, 2020 2:00:00 PM


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.

Video Tutorial: Connecting TOP Server with other OPC UA Servers

2 min read

By Kevin Rutherford on Aug 27, 2020 2:00:00 PM


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 you're not quite ready to move to OPC UA for all of your client applications, this provides the flexibility you need.

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.
