As more and more companies are making the switch from OPC-DA to OPC-UA, it is becoming increasingly important to be able to troubleshoot OPC-UA communications. One of the easiest ways to analyze the communication between an OPC-UA client and server is to use Wireshark.
This blog will cover step-by-step how to use Wireshark to troubleshoot communications between your OPC-UA client and server applications.
The OPC UA specification is an evolution on the original OPC Classic specifications that has been designed by the OPC Foundation to supplement, but not render obsolete the existing OPC standards such as DA, HDA, & A&E. OPC UA is designed to make enterprise-level integration easier, while ensuring compatibility and interoperability with existing OPC DA, HDA, and A&E servers and clients. OPC expert Marc Holbach gives a seminar on all of the details below.
The letters O - P - C get thrown around a lot these days in the context of the industrial automation industry. But it's important to understand that OPC is not a one-size-fits-all standard. There are different specifications under the OPC umbrella and it's not a safe assumption that they are all just compatible with each other because they typically are not.
This blog post will discuss how important it is to know which OPC specifications you have in use and whether the OPC tunneler solution you have or are considering can handle them all.
Have you ever been in a situation where you were working with both Wonderware and some other client (HMI, SCADA, other) and needed to share data? Perhaps your company acquired another company or assets and a non-Wonderware HMI/SCADA came as part of the assets. Or perhaps your company merged with another and now your Wonderware system is expected to play nicely with some other system. Your options for sharing data largely depend on what software interfaces this "other system" supports.
In this blog post, I'll discuss how to share your Wonderware ArchestrA or InTouch data via OPC UA for situations where you're working with an OPC UA capable client application that needs access to process data in your Wonderware system.
