OPC UA has changed machine-2-machine communications. OPC UA is a service-oriented communications standard that is based on IPV4 and IPV6. Its flexible architecture combined with the .NET Standard specification creates a powerful environment to rapidly develop OPC UA applications. The .NET Standard solves the code sharing problem for .NET developers across all platforms by bringing all the APIs that you expect across the environments that you need: desktop applications, mobile apps, and cloud services.
Softing is a leader in OPC UA technology and has released a new version of its dataFEED OPC UA .NET Standard Toolkits. Version 2.90 of the OPC UA .NET Standard Toolkits add the Pub/Sub MQTT protocol to the SDK, support for UMATI NodeSet files, NodesSet2 XML handling, and performance improvements for your next OPC UA development project.
