WCS is a management and control system between WMS system and PLC system. On the one hand, it interacts with the WMS system, receives the instructions from the WMS system, and sends them to the PLC system, so as to drive the equipment to carry out the corresponding mechanical action. On the other hand, it reflects the status and data of PLC system on the interface in real time, and provides manual debugging interface for PLC system and production line.

WCS system coordinates the operation of various logistics equipment, such as conveyor, stacker crane, shuttle car, robot, automatic guided car and so on. It adopts C / S architecture, mainly through task engine and message engine, optimizes task decomposition, analyzes execution path, provides execution guarantee and Optimization for upper system coodination instructions, and realizes the integration/unified coordination/monitoring of various equipment system interfaces.
