Abstract: A system and method for integrating a business transaction processing system, a process control system, and a laboratory system provides a computer integrated manufacturing environment. The manufacturing execution system receives work orders from the business transaction processing system and obtains enrichment data to enhance the work orders. The manufacturing execution system uses the enrichment data and rules contained in a plant model database to generate setpoints based on the received work orders. A subset of the work order data is provided to the laboratory system to direct sample testing. The setpoints include detailed information required by the process control system to manufacture the product specified by the work order. The setpoints are transmitted to the process control system for manufacture of the required materials.

Abstract: A system and method for controlling a communications adapter interface such that supplemental data can be interleaved with data being transferred. The interleaving is performed in a manner such that the supplemental data is transparent to the data mover portion of the communications adapter. The supplemental data can be transferred in either read or write cycles that are interleaved at the beginning, in the middle, or at the end of data bursts or block data transfers. As a result of the interleaving, the slave interface bus is more fully utilized because arbitration and bus ownership changes do not create unused cycles. The interleaving is accomplished by temporarily halting an existing transfer of data and transferring the requested supplemental data while the data transfer is halted. After the supplemental data is transferred, the transfer of the balance of the data block is then allowed to continue.
