OPC UA Applications

We offer OPC UA applications on a runtime license basis, ask for volume packages and redistributiuon discount for resellers.

UaGateway

UaGateway is a C++ based high performance wrapper/proxy to connect ‘classic’ COM/DCOM based OPC products. The UaGateway can be used in both directions at the same time. The wrapper is a UA Server that gets data from its internal COM DA2/DA3 (or Alarm&Event) client, which is connected to an underlying local classic OPC Server. 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 (or Alarm&Event) 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).

  • Wrapper
    The OPC UA wrapper enables a UA client to connect to a COM based OPC DA2/DA3 (or Alarm&Event or HistoricalDA) server. Internally the wrapper is a small UA server that gets data from its internal COM based classic OPC client. This client can be configured to connect to any compliant OPC server.
  • Proxy
    The OPC UA proxy enables a UA server to be accessed by a COM based OPC DA2/DA3 (or Alarm&Event or HistoricalDA) client. Internally the proxy consists of a COM based DA2/DA3 (or Alarm&Event or HistoricalDA) 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 related UA-Profile.
  • Tunnel
    When using two UaGateways on both sides you can tunnel the classic COM based communication over the secure OPC UA protocol. This will avoid the DCOM configuration, because you use local COM based access to the UaGateway on both sides, and all the remote traffic will be tunneled through secured OPC UA.
  • Mapping
    Equipped with the AddOn License for "Tagfile&Cache" the UaGateway can (instead of transparently pass trough all data) load a free configurable AddressSpace consisting of folders and items and map individual data points onto this custom representation.
