Abstract
An Open Platform Communications Unified Architecture (OPC UA) aggregation server for aggregating at least one OPC UA server in a remote address space is described. The at least one OPC UA aggregation server is configured to support data reduction and/or redundancy mechanisms.
Claims21
An Open Platform Communications Unified Architecture (OPC UA) aggregation server configured to:
- receive a first service request from an OPC UA client, the service request including a NodeId;
- where information pertaining to the service request is not available in a cache of the OPC UA aggregation server, use the NodeId of the service request to infer a URL of at least one OPC UA server and to calculate a NodeId of a node in a remote address space of the at least one OPC UA server;
- initiate a second service request to the at least one OPC UA server based on the first service request;
- filter data received from the remote address space of the at least one OPC UA server in response to the second service request via a configurable traffic filter using self-tuning traffic optimization logic;
- aggregate the filtered data in an aggregated address space of the OPC UA aggregation server;
- wherein the OPC UA aggregation server is configured for supporting data reduction and/or redundancy mechanisms;
- wherein the OPC UA aggregation server is configured to store remote address space information of a current session;
- wherein the session is related to an application and/or the OPC UA client;
- and
- wherein the OPC UA aggregation server is configured to use the remote address space information in a next session for aggregating data.

An Open Platform Communications Unified Architecture (OPC UA) aggregation system, comprising:
- an OPC UA client configured to send a first data request to an OPC UA aggregation server, the data request including a NodeId;
- an OPC UA aggregation server configured to:
- receive the first data request, and where information pertaining to the NodeId of the first data request is not available in a cache of has not been aggregated by the OPC UA aggregation server, use the NodeId of the first data request to infer a URL of at least one OPC UA server and to calculate a NodeId of a node in a remote address space of the at least one OPC UA server
- initiate a second data request to the at least one OPC UA server based on the first data request;
- filter data received from the remote address space of the at least one OPC UA server in response to the second data request via a configurable traffic filter using self-tuning traffic optimization logic;

- wherein the session is related to an application and/or a OPC UA client;
- and
- wherein the OPC UA aggregation server is configured to use the remote address space information in a next session for aggregating data.

A method for aggregating remote address space data in an Open Platform Communications Unified Architecture (OPC UA) system, comprising:
- requesting, by an OPC UA client, remote address space data from an OPC UA aggregation server, the request including a NodeId;
- where information pertaining to the request is not available in a cache of the OPC UA aggregation server, using the NodeId of the request to infer a URL of at least one aggregated OPC UA server and to calculate a NodeId of a node in an address space of the at least one OPC UA server:
- initiate a second request to the at least one OPC UA server based on the request of the OPC UA client;
- filter data received from the remote address space of the at least one OPC UA server in response to the second service request via a configurable traffic filter using self-tuning traffic optimization logic;
- aggregating, by the OPC UA aggregation server, remote address space data using data reduction and/or redundancy mechanisms;
- providing, by the OPC UA aggregation server, the requested remote address space data to the OPC UA client;
- and
- presenting, by the OPC UA client, the requested remote address space data;
- wherein the OPC UA aggregation server stores remote address space information of a current session;
- wherein the session is related to an application and/or the OPC UA client;
- and
- wherein the OPC UA aggregation server uses the remote address space information in a next session for aggregating data.
