Abstract
An elevator system including an elevator car having a first control disposed in the car, and a second control located remotely. Car calls are stored and serialized in the first control and sent to the second control at a first predetermined rate. Resets are serialized in the second control and sent to the first control at the first predetermined rate. When a plurality of cars are under control of a system processor, data is exchanged between the system processor and the second controls of the plurality of cars at a second data rate, which is a predetermined multiple faster than the first predetermined rate.
