Are you an AVEVA™ System Platform user but you also have some other client or system (HMI, SCADA, other) and need that system to access data from System Platform? It's a use case that sometimes occurs if your company is acquired another company and a non-AVEVA HMI/SCADA came as part of the assets. Or perhaps your company merged with another and now your AVEVA system is expected to integrate with other systems. Your options for sharing data largely depend on what software interfaces these "other systems" support.
In this blog post, I'll discuss how to share your AVEVA System Platform 2020 (or newer) data via OPC UA (without using OI Gateway) using the TOP Server OPC UA Client driver for situations where you have another non-OPC UA capable client application that needs access to process data in your AVEVA system.
