Abstract
A cell controller controls a machining cell including a plurality of work resources. The plurality of work resources include at least one processing machine and at least one robot. The cell controller includes a PLC and a management device. The PLC controls operation of the work resources in accordance with an instruction from the management device, and acquires conditions of a plurality of work elements including the work resources and a workpiece. The management device, in response to occurrence of abnormal stop of the machining cell, specifies a recoverable condition of each work element, and presents to an operator a guide to a recovery procedure that enables each work element to transition to the recoverable condition.
