<p><P>PROBLEM TO BE SOLVED: To facilitate the checking work of any abnormal state of each laser beam machining apparatus even when a plurality of laser beam machining apparatuses such as laser beam marking devices are used. <P>SOLUTION: In a laser beam machining apparatus unit system, a plurality of laser beam machining apparatuses are connected in a router network using, for example, a TCP/IP. Each laser beam machining apparatus is provided with an abnormality detection means 5, a self device abnormality storage means 6, a communication means 7, an other device abnormality storage means 8, and an abnormality detection output means 9. The communication means 7 performs the transmission/reception through the communication with a plurality of other devices, transmits any abnormal state (identification information and content of abnormality) of the self device to all other transmittable/receivable devices, and receives any abnormal state (identification information and content of abnormality) of other devices. By controlling any one of the laser beam machining apparatuses, abnormal states of the self device and other devices can be checked together, and any abnormal state of all laser beam machining apparatuses can be managed. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
