TopView for OPCUA (Pre-release)
May 4, 2022
Update May 31, 2022: TopView 6.37 with OPCUA support is now released.
About OPC UA
OPC UA stands for OPC Unified Architecture. It is an extensible, platform-independent standard that enables the secure exchange of information in industrial systems.
Many people are familiar with the older DCOM-based OPC, now called OPC Classic.
How is OPC UA different than OPC Classic?
- OPC Classic relies on Microsoft technologies while OPC UA is platform independent
- OPC Classic does not have built-in security for access control, authentication, and encryption
- OPC UA implements cross-platform security based on the public key infrastructure (PKI) using industry standard digital certificates
In the industrial software world, many vendors have added support for OPC UA, sometimes in addition to OPC Classic.
TopView for OPC UA
Our next release of TopView Alarm and Notification Software (v6.37) supports OPC UA. Our planned release for v6.37 is late May or early June.
TopView’s initial support for OPC UA will include the Data Access specification (DA) which is the ability to monitor the current value of “tags”. This is the same specification supported by our current TopView OPC/SCADA product which supports OPC Classic.
