A communications processor is disclosed for a power generation system that permits data and control signals to be communicated to and from the power generation system and a host computer. The control signals include a power level command and power factor that are sent from a remote host to the power generation system which responds by delivering the requested power level having the desired power factor to a grid. The remote host receives performance data that permits an operator to accurately gauge the performance of the power generation system including the performance and any fault conditions of a line power unit, generator, and engine driving the generator. The communications processor unburdens the line power unit controller that is responsible for controlling power generation from the task of processing input data and driving local displays. The host may also be provided at a location remote from the power generation system. The host, local or remote, preferably includes a graphical user interface that permits an operator to monitor and control the power generation system in an efficient and highly effective manner. A dedicated serial bus connects the communications processors of multiple power generation systems. By utilizing a round-robbin polling of each power generation system across the dedicated serial bus, real-time control can be achieved.
