Network technology

This system automatically conveys metal molds according to instructions received from an upper level cell controller. It controls AGV route switching and interfaces with an NC machine through the CC-Link. The CC-Link network drastically reduced wiring and the work period. A significant part of the wiring reduction was due to the high noise immunity of CC-Link, which imposed very few constraints on the routing of wires.

This line assembles automobile body with spot-welding and arc-welding robots. The line consists of 46 PLCs, installed 7 to 8 CC-Link manager units in each, and the total 2000 to 3000 of remote I/O units. The CC-Link reduced drastically wiring and cost. Also the time needed to do field installation work and wiring was drastically shortened because the easy connection of CC-Link to each piece of equipment. The efficiency and speed of the conveyor system was increased due to the high speed communication to the remote I/O made possible by CC-Link.

This system monitors the automatic operation and alarm conditions for machine rooms and electric equipment rooms. LAN connections and phone lines enable remote monitoring and maintenance. CC-Link I/O modules drastically reduce the wiring to air-conditioning units and other electrical equipment. The high-speed data link allows real-time display of the current status and error condition of equipment being monitored.
