Abstract:
An interface for a network card used with an industrial controller, the network card comprising:a dual-port memory partitionable to provide buffers for the passage of messages between the network card and the industrial controller; a connector half providing a releasable electrical interface between the dual-port memory and the industrial controller allowing access to the dual-port memory by the industrial controller when the connector half is connected to a corresponding connector half on the industrial controller; an electronic computer executing a stored program to: (i) receive via the dual-port memory an indication of at least one proposed new partitioning value for the dual-port memory from the industrial controller; and (ii) evaluate the proposed new partitioning value and if it is acceptable, re-partitioning the dual-port memory to comport with the proposed new partitioning value.
