Software Toolbox Technical Blog

If you've seen our other, more detailed posts (specifically our Exploring OPC UA post and the DataHub OPC UA video how-to) on getting Cogent DataHub working with OPC UA clients and servers, you are probably already familiar with configuring Cogent DataHub for secure access from an OPC UA client. However, we are commonly asked how to quickly get the DataHub OPC UA server interface ready for an OPC UA client to securely connect for accessing data from the variety of other interfaces that DataHub supports.

Continuing our Tech Support Corner blog series, this short post covers just the basics for setting up the Cogent DataHub OPC UA server interface to use the highest level of security and to require a client to specify a username and password for authentication.

Following on the recent OPC Data Client 2021.2 release a few months ago, the OPC Data Client toolkit has been updated again to further extend it's OPC UA client functionality. 

The new updates provide developers of custom OPC client applications with new operating system support, even more examples including Powershell examples, and a large number of improvements to all the supported OPC interfaces to increase flexibility, troubleshooting, and user experience, while further decreasing development time. 

OmniServer's connectivity and data parsing capabilities are its primary job; however, they are only part of how OmniServer helps with integrating non-standard devices with Inductive Automation's Ignition HMI/SCADA.  How does the device data actually make it into Ignition and what devices can you connect Ignition to using OmniServer?

In this video blog, I'll show you how to use OmniServer for TPI to integrate vibration data into Ignition via an OPC UA client connection from Ignition to OmniServer - all without the expense and headaches of having to write custom code.

Continuing our Exploring OPC UA blog series, we're still going into the specifics of OPC UA security configuration in key Software Toolbox solutions that are OPC UA capable.

In this ninth post of the series, we will focus on OPC Router, focusing on stepping through what the settings are in OPC Router and how to get connected both for your OPC UA clients and servers.

If you've been following our ongoing Exploring OPC UA blog series, we've been covering key Software Toolbox solutions and the specifics of configuring OPC UA security and connectivity.

In this eighth post of the series, we will focus on the OPC Data Client development toolkit, with the primary topic being how to exchange security certificates and establish a trust relationship between your custom OPC UA client and an OPC UA server.

IoT, IIoT, MQTT, Connectivity of Things, Big Data, The Cloud - by now, you've heard these terms in some way, shape or form.  Perhaps you're working on a project requiring you to push and/or pull important process or business data to/from a cloud solution. Big data analytics applications ranging from predictive maintenance to "smart" manufacturing, amongst many other use cases, are becoming more and more common.

And Google© is a household name both in the private and professional world. Chances are, you got here using Google – whether through a Google search, or by using Google Chrome (or both). But did you know that Google has their own cloud solution called Google Cloud IoT Core©? Amongst many other things, Google Cloud IoT Core acts as an MQTT broker for storing and sharing important data in a secure cloud along with artificial intelligence and analytics and many other IoT services.

But how do you go from your data sources to Google Cloud IoT Core? In this second post in a series about connecting DataHub to IoT solutions (if you missed our first post on connecting to Amazon AWS IOT Core©, click here), we'll step through how you can configure Google Cloud IoT Core and connect it to your process and business data sources using the Cogent DataHub IoT Gateway©.

Following on the recent OPC Data Client 2021.1 release a few months ago, the OPC Data Client toolkit has been updated again to further extend it's OPC UA client functionality. 

The new updates provide developers of custom OPC client applications new options to interact with even more OPC UA servers or more richly with existing OPC UA servers. This blog post teaches you how OPC UA PubSub security is different from regular OPC UA security, how to improve JSON/OPC UA PubSub interoperability with a new utility, and why you might care about OPC UA File Transfer. 

If you've been following our ongoing Exploring OPC UA blog series, we've been covering key Software Toolbox solutions and the specifics of configuring OPC UA security and connectivity.

In this seventh post of the series, we will focus on OPC Data Logger, specifically stepping through settings related to security, endpoints and certificate management and connecting OPC Data Logger to OPC UA servers for logging data.
