Chapter 1  TC-net 100
Network Configuration
The information and control network TC-net 100 of the Integrated Controller V Series 
permits selection of a system using optical fiber cables or a system using twisted-pair 
cables.
An optical fiber cable system employs optical TC-net 100 modules and optical shared 
hub units connected with optical fiber cables having an MT-RJ connector to form a 
network.
General Ethernet devices can be connected to the TC-net 100 through a multiport unit 
(under development).
