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

3 min read

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.

Video How-To: Connect Non OPC-UA Clients to UA Servers with TOP Server

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 your client does not support OPC UA, but does support one of TOP Server's other client interfaces, TOP Server can be the gateway solution. This is especially valuable for AVEVA users who wish to keep using AVEVA Suitelink, OPC DA, or have not migrated to a version of AVEVA applications that support OPC UA Client functionality. 

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.

With the rising security demands of Industry 4.0, OPC UA provides us with the means to encrypt data as it is transferred between client and server. But what if encrypting data to prevent outside extraction is not enough? What if UA client applications become compromised? What tools do we have to protect against deliberate or even accidental manipulation or consumption of data?

Continuing our Tech Support Corner blog series, this post covers how to leverage the built-in TOP Server User Group Security settings, alongside OPC UA username and password authentication, for greater control over which users have read/write capabilities as well as what tags a user is permitted to access.

Top 3 TOP Server OPC UA Client Use Cases

5 min read

Standards-based industrial device connectivity such as OPC has become the norm over the last 20 years.  What used to be achieved by individual HMI/SCADA vendors with their own native drivers can now be easily accomplished with OPC drivers that are HMI/SCADA vendor agnostic.  TOP Server offers connectivity to thousands of device types and protocols while making those devices accessible via a variety of standard interfaces including OPC UA, OPC DA and SuiteLink.

But what you may not be aware of is that TOP Server for Wonderware has an available driver suite called the OPC Client Suite that allows it to also act as an OPC UA client, OPC DA client and OPC XML-DA client.  In this post, I'm going to go through the top 3 most common use cases for the OPC Client Suite that we see users take advantage of.
