A system and method for processing semiconductor wafers using different wafer processes utilizes multiple processing assemblies to efficiently perform these wafer processes. The apparatus includes a chassis and a reservoir for holding water to be dispensed via a dispensing tube in fluid communication with the reservoir. The communications device 105 includes a network interface unit 100, a network controller 103 communicating with the device 106 and others, and a CPU controlling these components. Previously stored converted values are pushed to the second level of the buffer when a new value is written to the first level.
