WCS storage control system is a management control system between WMS system and PLC system. On the one hand, it carries on the information interaction with the WMS system, accepts the instruction of the WMS system, and sends it to the PLC system, so as to control and dispatch the operation of various equipment in the automated warehouse, including conveyor, stacker, elevator, shuttle and other logistics equipment. On the other hand, it will reflect PLC system status and data on the interface in real time, and provide the PLC system and production line manual debugging interface. WCS is mainly through the task engine and message engine, optimize the decomposition of tasks, analyze the execution path, provide execution guarantee and optimization for the scheduling instructions of the upper system, and realize the integration, unified scheduling and monitoring of various equipment system interfaces.
