1.2 Terminology
Term Description
CC-Link IE
Field related
Master station
A station that controls the entire network. This station can perform cyclic
transmission and transient transmission to all stations.
Slave station
A generic name of all stations other than master stations (local stations,
remote I/O stations, remote device stations, and intelligent device sta-
tions)
SC-LG2-CEF-P
An IO-Link master compliant with CC-Link IE Field.
This master connects IO-Link devices using e-CON connectors.
PNP connection is based on the I/O interface specifications of IO-Link
devices.
CC-Link IE Field net-
work
A high-speed and large-capacity open field network using Ethernet
(1000BASE-T)
Cyclic transmission
A function that periodically exchanges data between stations on the
same network in the data link layer
Transient transmission
A function that uses the read/write instructions of the program at the lo-
cal station to read and write data from / to remote stations and commu-
nicate with remote stations via peripheral devices in the data link layer
Memory map
A memory map where the functions of the communication unit are al-
located to link devices. The master station can use the functions of
the communication unit by accessing the link devices allocated on the
memory map.
Link device Internal devices held by the unit (RX, RY, RWr, and RWw)
Network number
A unique number that is assigned to identify each network when mul-
tiple networks are created.
Duplicate numbers cannot be set among all networks.
Station number
A unique number that is assigned to identify each network unit that is
connected to a network.
Duplicate numbers cannot be set among all network units within a net-
work.
Intelligent device sta-
tion
A station that cyclically transmits bit-based I/O signals and word-based
I/O data to the master station. This station returns responses to tran-
sient transmission requests from other stations.
