With OPC DA Classic having been the de-facto standard for integrating industrial automation systems for so many years, I'm sure there are quite a few of you who might have custom developed OPC DA servers using SLIK-DA. Now, of course, migrations to OPC UA are on the rise with its enhanced security, encryption and efficiency.

Of course, the prospect of replacing that OPC DA server entirely with a replacement that supports OPC UA might be less than ideal. But have you considered adding an OPC UA server interface to that existing OPC DA custom application?

In this video blog, we teach you how to add an OPC UA Server interface to your existing OPC DA Server interface using the SLIK-DA/UA rapid development toolkit with your custom software application (NO ADDITIONAL CODE).

So your organization has a custom developed application that is performing some important task and you've been tasked with providing access to that software for an OPC DA client or clients. Adding an OPC DA server interface to a custom application that either you've developed or that you've taken over from someone else can be a daunting task.  This is especially true if you're unfamiliar with the low level nuts and bolts of the OPC DA Classic specification.

In this video blog, we teach you how to add an OPC DA Server interface to your custom software application using the SLIK-DA/UA rapid development toolkit.

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.
