TERMS
Unless otherwise specified, this manual uses the following terms.
Term Description
Buffer memory
A memory in an Ethernet adapter module, where data (such as Ethernet port information, setting values,
and monitoring values) are stored
CC-Link IE Field Network A high-speed and large-capacity open field network that is based on Ethernet (1000BASE-T)
Configuration tool A software package built in an Ethernet adapter module
Cyclic transmission
A function by which data are periodically exchanged among stations on the same network using link devices
(RX, RY, RWw, and RWr)
Data link A generic term for cyclic transmission and transient transmission
Dedicated instruction An instruction that simplifies programming for using functions of intelligent function modules
Device A device (X, Y, W, or others) in an Ethernet adapter module
Disconnection A process of stopping data link if a data link error occurs
Ethernet adapter module The abbreviation for the NZ2GF-ETB CC-Link IE Field Network Ethernet adapter module
External device A generic term for devices that send SLMP request messages to an Ethernet adapter module
GX Works2 The product name of the software package for the MELSEC programmable controllers
Intelligent device station
A station that exchanges I/O signals (bit data) and I/O data (word data) with the master station by cyclic
transmission. This station responds to a transient transmission request from another station and also issues
a transient transmission request to another station.
Link device A device (RX, RY, RWr, or RWw) in a module on CC-Link IE Field Network
Link special register (SW) Word data that indicates the operating status and data link status of a module on CC-Link IE Field Network
Link special relay (SB) Bit data that indicates the operating status and data link status of a module on CC-Link IE Field Network
Local station
A station that performs cyclic transmission and transient transmission with the master station and other local
stations.
The station is controlled by programs in the CPU module or other equivalent modules on the station.
Master station
A station that controls the entire network.
This station can perform cyclic transmission and transient transmission with all stations.
Only one master station can be used in a network.
Master/local module
A generic term for the CC-Link IE Field Network master/local modules: QJ71GF11-T2, QS0J71GF11-T2,
and LJ71GF11-T2
Network module
A generic term for the following modules:
• Module on CC-Link IE Field Network
• CC-Link IE Controller Network module
• Ethernet interface module
• MELSECNET/H module
• MELSECNET/10 module
Parameter memory
A flash ROM in an Ethernet adapter module, where the parameters of the Ethernet adapter module are
stored
Relay station
A station that includes two or more network modules. Data are passed through this station to stations on
other networks
Remote device station
A station that exchanges I/O signals (bit data) and I/O data (word data) with the master station by cyclic
transmission. This station responds to a transient transmission request from another station.
Remote I/O station A station that exchanges I/O signals (bit data) with the master station by cyclic transmission
Remote input (RX)
Bit data input from a slave station to the master station (For some areas in a local station, data are input in
the opposite direction.)

User's manual for the master/local module used
Remote output (RY)
Bit data output from the master station to a slave station (For some areas in a local station, data are output
in the opposite direction.)
 User's manual for the master/local module used
Remote register (RWr)
Word data input from a slave station to the master station (For some areas in a local station, data are input
in the opposite direction.)

User's manual for the master/local module used
Remote register (RWw)
Word data output from the master station to a slave station (For some areas in a local station, data are
output in the opposite direction.)

User's manual for the master/local module used
Request message An SLMP message sent from an external device to an Ethernet adapter module
