Wrapper and proxy are high performance applications that are used to connect to legacy COM/DCOM based OPC products. Written in C++ these components are installed out of the box and can be configured to map OPC DA servers onto UA-TCP binary communication. We offer these product on a runtime license basis, ask for volume packages and redistributiuon discount for resellers.
The OPC UA wrapper enables a UA client to connect to a COM based OPC DA2/DA3 server. Internally the wrapper is a small UA server that gets data from its internal COM DA2/DA3 client. This client can be configured to connect to any compliant OPC server.
The OPC UA proxy enables a UA server to be accessed by a COM based OPC DA2/DA3 client. Internally the proxy consists of a COM based DA2/DA3 server that gets it's data from it's internal UA client. This client can be configured to connect to any UA server that supports the DA-Profile.
UaGateway is a C++ based high performance wrapper/proxy to connect ‘classic’ OPC Data Access products. The UaGateway can be used in both directions at the same time. The wrapper is a small UA Server (only DataAccess) that gets data from its internal COM DA2/DA3 client. The wrapper is needed when connecting new UA Clients to legacy, ‘classic’ OPC Server. The UaGateway additionally supports the opposite direction being a proxy. The proxy consists of a COM based DA2/DA3 server that gets its data from its internal UA client. The proxy is needed when connecting legacy, ‘classic’ OPC Clients to new OPC UA Server(s).
