General methodology for building of OPC UA gateways

Abstract

This article describes an original generalized methodology for building OPC UA bridges for different industrial communications and internal command protocols. This methodology is aimed for fast development of OPC UA gateways for less popular data transferring communications which are not available on the market. A final gateway can be added to existing solutions without modification of data source control devices. This gateway needs only a minimal configuration and obtains information about data source automatically. This design has been already implemented in three different solutions with various communication (REXYGEN, PerNet, a Keysight middleware protocol). The solutions has been deployed in various projects and proved to be efficient and reliable.
