Mitsumi electronic NZ2GF-ETB ユーザーズマニュアル

13

Unless otherwise specified, this manual uses the following terms.

CC-Link IE Field Network

A high-speed and large-capacity open field network that is based on Ethernet (1000BASE-T)

Master/local module

A generic term for the CC-Link IE Field Network master/local modules: QJ71GF11-T2, QS0J71GF11-T2, 
and LJ71GF11-T2

Ethernet adapter module

The abbreviation for the NZ2GF-ETB CC-Link IE Field Network Ethernet adapter module. 

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

External device

A generic term for devices that send SLMP request messages to an Ethernet adapter module

Configuration tool

A software package built in an Ethernet adapter module

GX Works2

The product name of the software package for the MELSEC programmable controllers

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.

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.

Remote I/O station

A station that exchanges I/O signals (bit data) with the master station by cyclic transmission

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.

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.

Slave station

A generic term for stations other than a master station: local station, remote I/O station, remote device 
station, and intelligent device station

Reserved station

A station reserved for future use. This station is not actually connected, but counted as a connected station.

Relay station

A station that includes two or more network modules. Data are passed through this station to stations on 
other networks

Cyclic transmission

A function by which data are periodically exchanged among stations on the same network using link devices 
(RX, RY, RWw, and RWr)

Transient transmission

A function of communication with another station, which is used when requested by a dedicated instruction 
or GX Works2

Data link

A generic term for cyclic transmission and transient transmission

Routing

A process of selecting paths for communication with other networks.
CC-Link IE Field Network requires communication paths to be preset using routing parameters to 
communicate with stations on different networks.
An Ethernet adapter module does not require routing parameters. Communications with other networks are 
performed according to the routing parameters set to the master station.

SLMP

The abbreviation for Seamless Message Protocol.
This protocol is used to access an SLMP-compatible device or a programmable controller connected to an 
SLMP-compatible device from an external device.

Request message

An SLMP message sent from an external device to an Ethernet adapter module

Response message

An SLMP message sent from an Ethernet adapter module to an external device

Dedicated instruction

An instruction that simplifies programming for using functions of intelligent function modules

Return

A process of restarting data link when a station recovers from an error

Disconnection

A process of stopping data link if a data link error occurs

Device

A device (X, Y, W, or others) in an Ethernet adapter module

Link device

A device (RX, RY, RWr, or RWw) in a module on CC-Link IE Field Network
