TERMS
The abbreviation for the NZ2GF-CCB CC-Link IE Field Network CC-Link bridge module
A memory in a bridge module, where data (such as setting values and monitoring values) are stored
A field network system where data processing for control and information can be simultaneously performed at high
speed.
The abbreviation for the Ver.1.10-compatible CC-Link dedicated cable
A high-speed and large-capacity open field network that is based on Ethernet (1000BASE-T)
A generic term for CC-Link remote I/O stations and remote device stations
A function by which data are periodically exchanged among stations on the same network using link devices (RX, RY,
RWw, and RWr)
A generic term for cyclic transmission and transient transmission
An instruction that simplifies programming for using functions of intelligent function modules
A device (X, Y, M, D, or others) in a CPU module
A process of stopping data link if a data link error occurs
A generic term for GX Works2 and GX Works3
The product name of the software package for the MELSEC programmable controllers
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.
A device (RX, RY, RWr, or RWw) in a module on CC-Link IE Field Network and CC-Link
Time required for all stations in a system to transmit data. The link scan time depends on data volume and the number
of transient transmission requests.
Word data that indicates the module operating status and data link status of CC-Link IE Field Network and CC-Link
Bit data that indicates the module operating status and data link status of CC-Link IE Field Network and CC-Link
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.
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 station" after Chapter 1 in this manual is a CC-Link IE Field Network master station. A master station on CC-
Link is described as "CC-Link master station".)
A generic term for CC-Link IE Field Network master/local modules
A station that includes two or more network modules. Data are passed through this station to stations on other
networks.
Buffer memory in a 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.
A station that exchanges I/O signals (bit data) with the master station by cyclic transmission
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
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
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
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
A station reserved for future use. This station is not actually connected, but counted as a connected station
A process of restarting data link when a station recovers from an error
