How to Develop Custom OPC Clients with No Code

By Ganesh Kalipershad on Jul 30, 2020 2:00:00 PM

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 Server Development Toolkit?

By Ganesh Kalipershad on Jun 25, 2020 2:00:00 PM


As technical consultants at Software Toolbox, we are often approached by users who need to expose data from a software application they have written, or are writing, to communicate from systems they own to a client, HMI/SCADA, or historian. And, in many cases, there are dozens of applications at different sites that the data needs to reach. The question we are then presented with is, “how can I accomplish this quickly and efficiently while staying within budget?” 

Continuing our OPC Development Toolkits blog series, our hope is to answer this question and 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 server toolkit, and to help readers determine what factors to consider for their specific situation and circumstances.

In the first part of this series, we covered the basics of commercial OPC client development toolkits, with a dive into the benefits of using one, while here in part 2, our focus is on OPC server development toolkits. If you read our blog on OPC client toolkits, you will likely notice a clear overlap in the benefits you gain from using both types of commercial OPC toolkits.

Why use an OPC Client Development Toolkit?

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.
