Apendix 1 100M-Ethernet Control LAN Network Configuration
120
Basic Configuration
The 100M-Ethernet control LAN basically uses a transmission path configuration specified by
the IEEE802.3u.
When the OIS-DS and SVR-DS are installed in an optimal environment in terms of noise in the
operator room, etc., twisted pair cables are used for wiring in the operator room.
Since the PCS-DS is installed in the field or control room, etc., the PCS-DS is connected inside
the cabinet to a HUB or FX-TX conversion module from the PCS-DS body using twisted pair
cables taking account of influences of noise, etc. Wiring from the cabinet to the outside is
performed using optical fiber.
