Ethernet Control Lan; System Configuration - Toshiba TOSDIC-CIE DS Instruction Manual

Appendix
2. 100M Ethernet Control LAN
For the 100M Ethernet Control LAN, basically the transmission line configuration specified in the IEEE802.3u
is used.
If OIS-DS and SVR-DS are installed at a place such as an operator room with good environment (e.g. low noise),
twisted pair cables are used in wiring within the operator room.
Since PCS-DS is installed at site or in a control room, twisted pair cables are used for internal wiring to connect
the PCS-DS main unit to hubs or FX-TX conversion modules to minimize the effect of noises. For external
wiring, optical fiber cables are used.

2.1 System Configuration

The standard system configuration is a redundant configuration with two systems of transmission lines.
Figure 2.1 is an example of system configuration.
