Abstract
A method and apparatus for sorting units of material includes a transport media formed in a plurality of segments. A plurality of actuators and at least one of an identification sensor, a segment sensor, a length sensor are connected with respect to the transport media. A parameter of a unit of material is sensed to generate a data update and calculate control outputs in a sort logic controller. The control outputs are sent from the sort logic controller to a network controller for the sensors and actuators. The network controller is synchronized to the output of the sort logic controller to receive and read the outputs, which are written together to the network memory, as soon as they are written from the sort logic controller. The output signal based upon the data update is then immediately multicast through the network to at least one actuator and the units of material are sorted based upon the output signal.
