Component mounting line management device

A component mounting line management device comprising:

• a component mounting line in which a plurality of component mounting machines is arranged, the component mounting machine mounting a component on a printed circuit board;
• and
• a configuration management device that is connected to each of the component mounting machines through a communication line, and stores installation device identification information and location information in correlation with each other, the installation device identification information being for identifying each of a plurality of installation devices, which is detachably attached at an installation position of the component mounting machine, and the location information indicating an installation position of the installation device in the component mounting machine,
• wherein the configuration management device includes a communication-normal-time installation device determination section,
• he communication-normal-time installation device determination section receives transmission of the installation device identification information of the installation device and the location information on the installation position when the installation device is attached at the installation position, from the component mounting machine, and compares the transmitted installation device identification information and the transmitted location information to installation device identification information of the installation device and location information correlated with the installation device identification information which are stored in the configuration management device, so as to determine whether the installation device is used, each of the component mounting machines or each of the installation devices includes an installation device information memory device,
• the installation device information memory device stores the installation device identification information of the installation device attached at the installation position, and the location information on the installation position in correlation with each other,
• each of the component mounting machines includes a communication-abnormal-time installation device determination section, and
• the communication-abnormal-time installation device determination section compares the installation device identification information of the installation device attached at the installation position and the location information on the installation position when communication with the configuration management device is impossible, to installation device identification information of the installation device and location information correlated with the installation device identification information which are stored in the installation device information memory device, so as to determine whether the installation device is used.
