1.5 Basic FL-net Terminology
The following gives an overview of basic FL-net terminology.
FA equipment
Refers to an FA system component device connected to FL-net. Control equipment (controllers) such as the pro-
grammable controller (PLC), computer numeric control (CNC) equipment, and personal computer (PC) are all
classified as FA equipment.
Network
Refers to a local area network (LAN) whose data link level complies with IEEE802.3 in FL-net. The existing
standard supports a baud rate of 10 Mbps in both 10BASE5 and 10BASE-T.
Node
Refers to FA equipment connected to FL-net. Each node is assigned a node number (1 to 254) for identification.
Communication unit
Generally, refers to a set of a communication board and communication module necessary for communication via
FL-net.
Networking equipment
Refers to IEEE802.3-compliant communication devices such as communication cables, transceivers, and hubs
necessary for communication via FL-net.
Switching hub
Refers to a hub (line concentrator) equipped with a bridge function. A received packet is temporarily stored in the
buffer for regenerative relaying.
Repeater hub
Refers to a hub (line concentrator) equipped with functions for electrically regenerating and relaying transmis-
sion signals on cables.
