Abstract

A multi-generation distributed control system includes a first generation (FG) DCS connected to a local control network (LCN) including FG client nodes. A second generation (SG) DCS connected to a non-LCN data highway includes a server node connected between the LCN and the non-LCN data highway and SG client nodes. The server node includes a LCN processor (LCNP) board. LCNP emulator software including a server LCNP emulator software component is at the server node and a client LCNP emulator software component at the SG client nodes. The server LCNP emulator software component translates between LCN data and data highway protocol data and adds one of a plurality of LCN address slots to communications received from the LCN for delivery to the SG DCS that each correspond to a SG client node. Each client LCNP emulator software component provides one of the LCN address slots at its SG client node.
