If you read our last post on sharing XML data, you may recall that our tech support engineers are regularly asked how to take data provided in an XML (eXtensible Markup Language) format (file or data stream) and share it with other systems such as OPC clients or servers, databases, devices or even the cloud.

In this Integrating XML Data sub-topic of our continuing Tech Support Corner blog series, this post covers how to easily integrate XML data with OPC systems when designing a custom developed application.

How to Develop Custom OPC Clients with Minimal Code

As we discussed in the first post of this series, the term "OPC client" often refers to off-the-shelf HMI or SCADA applications.  OPC clients can also be other custom developed software applications in your enterprise that could benefit from access to OPC process data.  Or there might be a new custom application you need to develop that requires access to OPC process data.  In those situations, you need a reliable, straightforward method to enable those applications as OPC clients.

In Part 2 of our series on How to Develop Custom OPC Clients, we will cover step-by-step how to use low-code techniques to read, write and subscribe to OPC process data through building a basic OPC client application in Visual Studio.NET.

When you hear the term "OPC client", you may initially think of off-the-shelf HMI or SCADA applications.  However, it's common in enterprises across most industries for there to be other custom developed software applications that could benefit from access to OPC process data.  Or perhaps there is a new custom application you're working on that needs to access OPC process data.  The question, then, is how to enable those applications as OPC clients.

In Part 1 of our series on How to Develop Custom OPC Clients, we will cover step-by-step how to use no-code techniques to bind production data to various types of user interface elements for reading, or writing, or both to build a basic OPC client application in Visual Studio.NET.

Why use an OPC Client Development Toolkit?

8 min read

By Ganesh Kalipershad on May 21, 2020 2:00:00 PM


A common question we are asked as technical consultants at Software Toolbox is “why should I use an OPC toolkit when there is free sample code and other free solutions available to me?” That’s a fair and logical question, but this post takes a different approach. 

Instead, with this 2-part blog series, our hope is to share from our experience with OPC since 1996, what our users have told us are the common reasons why they chose to use a commercial OPC toolkit, and to help readers determine what factors to consider for their specific situation and circumstances.

In the first part of this blog series on OPC development toolkits, we will cover the basics of commercial OPC Client Development Toolkits, with a dive into the benefits of using one, while in part 2, we will look at OPC Server Development Toolkits.
