In addition to OPC UA Architecture specifications that that BP ELIOT GW & CPE follows, it was recommended to follow (get uppdated) on the 3GPP specified CIoT for 5G specifications due to major enhancements embedded in the 5GS Architecure for IoT related to RG with support for MA through 3IWG & N3IWG and ATSSS and several/many more (e.g UPF in chain/series connection and RRC Inactive with enhanced security and move of LMF to RAN. The OPC UA was initially released in 2006 - 2008 and has a very broad Market deployment footprint since then. OPC UA specificifies a Platform independent Service-oriented Architecture, that integrates all the functionality of the individual OPC Classic Specifications into one (1) extensible Framework. OPC UA specifications are stipulated in International Standard IEC 62541 62 541 (https://opcfoundation.org/news/opc-foundation-news/update-iec-62541-opc-ua-published/). The current version of the OPC UA specification is on 1.04 (22 November 2017). The new version of OPC UA now has added Publish/Subscribe in addition to the Client/Server communications infrastructure. The OPC UA Information Model is a so-called Full Mesh Network based on nodes. The OPC UA Architecure supports two (2) Protocols. This is visible to Application programmers only via changes to the URL. The binary protocol is opc.tcp://Server and http://Server is for Web Service. Otherwise OPC UA works completely transparent to the API.
