Abstract
An electrical control system is disclosed for industrial conveyor systems which includes plural individual conveyors. The system includes a single main controller and a sub-controller for each individual conveyor in the system. Each sub-controller is located adjacent its own conveyor and is wired directly to the input and output devices of its own conveyor, thus requiring only localized field wiring for the electrical system. The control logic for each individual conveyor and the overall conveyor system is provided by a programmable controller in the main controller coupled through a communication line to the sub-controllers. The electrical control system is provided with a diagnostic system with the diagnostic circuitry located in each of the sub-controllers. Each of the sub-controllers is provided as a standardized module with a printed circuit board containing all of the interconnections required by the sub-controller except the local wiring connections to the conveyor itself.
