Production controller equipped with function of identifying cause upon operation stop of production facility including manufacturing facilities

摘要

A cell controller includes a first communication unit which receives a task program and signal setting information stored in each manufacturing machine from this manufacturing machine, a stop detection unit which refers to the task program and the signal setting information to detect whether a production facility has stopped operation, and a stop cause identification unit which analyzes the task program and the signal setting information to identify the manufacturing machine that has caused the operation stop of the production facility, and this cause. Such a cell controller can detect whether a production facility including manufacturing machines has stopped operation, and automatically identify the manufacturing machine that has caused this operation stop, and this cause.
