GENERIC TERMS AND ABBREVIATIONS
Unless otherwise specified, this manual uses the following generic terms and abbreviations.
Term Description
Authentication Class A group of devices and switching hubs compatible with CC-Link IE TSN, ranked according to the functions and
performance by the CC-Link Partner Association (www.cc-link.org).
Cyclic transmission A function by which data is periodically exchanged among stations on the same network using link devices
Data link Communications performed by cyclic transmission and transient transmission
Disconnection Processing for stopping the data link when a data link error occurs
Engineering tool A tool for setting, programming, debugging, and maintenance of programmable controller.
GX Works3 A generic product name for SWnDND-GXW3. ('n' indicates its version.)
Link device A device in a module on CC-Link IE TSN
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.
Remote station A station that exchanges I/O signals (bit data) and I/O data (word data) with another station by cyclic transmission. This
station can perform transient transmission.
Return Processing for resuming the data link when a faulty station becomes normal
RWr A remote register of the link device. RWr refers to 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.)
RWw A remote register of the link device. RWw refers to 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.)
RX A remote input of the link device. 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.)
RY A remote output of the link device. 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.)
Slave station A station other than a master station: a local station, a remote station
SLMP An 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.
TCP/IP communications One of the standard network protocols used for internet communications.
SLMP (SeamLess Message Protocol) is a communication method that uses TCP/IP.
Transient transmission A function of communications with other stations, which is used when requested by a dedicated instruction or an
engineering tool
