Abstract
Method and apparatus to provide protocol translation and selectable data exchange in a client/server system are provided. A tag list is extracted from a legacy client device 116 connected to a legacy server 114 using a protocol corresponding to the legacy server. A configuration manager device 120 is used to configure the extracted tag list to obtain a selected tag list excerpt of the extracted tag list. The configuring device is arranged to map the selected tag list excerpt to a configuration adapted for a respective 112 server, and to define contextualization. Server 112 provides industrial automation services using a next-generation protocol, e.g., OPC UA or MTConnect. A tag list is generated to configure server 112. A stream of data points of the selected tag list excerpt of the tag list extracted from the legacy client device is transferred to one or more client devices 124 connected to server 112.
