Each controller includes a plurality of bi-directional communication ports (14a, 14b, 15a, 15b), a processor (12) that processes information and provides outputs, where at least one output controls the device, and an application program for execution within the processor (12) that includes instructions and criteria for processing the information and providing the processor outputs. Specifically, the applications program includes instructions and criteria for communicating information between and among controllers; instructions and criteria for processing information received by a controller; and instructions and criteria for modifying the operation of a device responsive to the communicated information. For a conveying system having a multiplicity of conveying sections, a controller is provided for each section.</p> |
