State change management system for manufacturing cell in cell control system

A state change management system of a manufacturing cell in a cell control system, wherein

• the cell control system is connected via a communication device to a manufacturing cell composed of multiple manufacturing machines including at least one of a robot, a PLC, and a machine tool for manufacturing a product, and is connected via the communication device to a production planning device that performs production planning of the product manufactured by the manufacturing cell, and
• the state change management system comprises:
• an event information monitoring part that receives, from the manufacturing cell, event information items in different forms generated from the multiple manufacturing machines, the event information items including at least one of an alarm, a warning and a change in machining condition, to thereby monitor a state change in the multiple manufacturing machines;
• a standard information creation part that executes a process of converting the event information items in the different forms received by the event information monitoring part into a standardized form, the process including a process of standardizing formats and a process of standardizing languages;
• and
• a standard information output part that outputs event information in a standardized form created by the standard information creation part to the production planning device.
