Abstract
Contiguous independently-controllable conveyor system zones are controlled by zone control modules executing a program element associated with each module. Each module is coupled with an object detector and a conveyor zone actuator. A two-way zone control module communication port is coupled with two adjacent upstream zone control module communication ports and two adjacent downstream zone control module communication ports. An object detector port is coupled with an object detector, an actuator control port is coupled with an actuator, and a conveyor zone actuator is thereby controlled. Memory allocation in a module includes an event logic element responsive to inputs from adjacent upstream and downstream module communication ports. A program element associated with each module identifies the position of the module in a series of modules. The actuator is controlled by an event logic element, and by communication from an object detector and an adjacent upstream and downstream module.
