A factory-automation network solution: backbone communications with CC-Link support, offering a high degree of freedom in network configuration.
CC-Link communication can also be replaced with a high-speed wireless optical (infrared) communication system, enabling fantastic reduction of wiring.
Optically transmit CC-Link data.
The CC-Link cable can be replaced with wireless optical communication.
Wireless reception can be transmitted to a master unit,facilitating optical-axis adjustment and improving maintainability.
Communication speeds of 156 k, 652 k, and 2.5 Mbps supported.
