TRB255 OPC UA Server
The information in this page is updated in accordance with firmware version TRB2_R_00.07.06.10.
Summary
OPC Unified Architecture (OPC UA) is a cross-platform, open-source, IEC62541 standard for data exchange from sensors to cloud applications developed by the OPC Foundation. The UA in OPC UA stands for “Unified Architecture” and refers to the latest specification of the standard. It differs from its predecessor in that it is platform-independent, moving away from COM/DCOM to purely binary TCP/IP or alternatively SOAP.
This manual page provides an overview of the OPC UA Server in TRB255 devices.
Note: OPC UA Server is additional software that can be installed from the System → Package Manager page.
