Label A label that represents a device in a given character string
Link device A device in a module on CC-Link IE
Link refresh Automatic data transfer between a link device in a module on CC-Link IE and a device in a CPU
module. Link refresh is performed in the END processing of the CPU module's sequence scan.
Link register (LW) Word data send from each station on CC-Link IE Controller Network
Link relay (LB) Bit data send from each station on CC-Link IE Controller Network
Link scan (link scan time) Time required for all the stations on the network of CC-Link IE to transmit data.
The link scan time depends on data volume and the number of transient transmission requests.
Link special register (SW) Word data that indicates the operating status and data link status of a module on CC-Link IE
Link special relay (SB) Bit data that indicates the operating status and data link status of a module on CC-Link IE
Local station A station that performs cyclic transmission and transient transmission with the master station and other
local stations on CC-Link IE Field Network.
Master operating station A station that controls the entire network when the submaster function of CC-Link IE Field Network is
used. Only one master station can be used in a network.
Master station A station that controls the entire network on CC-Link IE Field Network. This station can perform cyclic
transmission and transient transmission with all stations. Only one master station can be used in a
network.
MELSECNET/10 An abbreviation for the MELSECNET/10 network system
MELSECNET/H An abbreviation for the MELSECNET/H network system
MODBUS/TCP A generic term for protocols for using a message of MODBUS protocol on TCP/IP network
Module label A label that represents one of memory areas (I/O signals and buffer memory areas) specific to each
module in a given character string.
For the module used, GX Works3 automatically generates this label, which can be used as a global
label.
Network module A generic term for the following modules:
• Ethernet interface module
• CC-Link IE Controller Network module
• Module on CC-Link IE Field Network
• MELSECNET/H network module
• MELSECNET/10 network module
• RnENCPU (network part)
Normal station A station that performs cyclic transmission and transient transmission with the control station and other
normal stations on CC-Link IE Controller Network
Predefined protocol support function A function of GX Works3.
This function sets protocols appropriate to each external device and reads/writes protocol setting data.
Process CPU A generic term for the R08PCPU, R16PCPU, R32PCPU, and R120PCPU
Process CPU (redundant mode) A Process CPU operating in redundant mode.
A redundant system is configured with this CPU module. Process control FBs and the online module
change function can be executed even in this mode.
RAS An abbreviation for Reliability, Availability, and Serviceability. This term refers to the overall usability of
automated equipment.
Redundant function module Another term for the R6RFM
This module is used with the Process CPU (redundant mode) as a pair and configures a redundant
system.
Redundant system A system consisting of two systems that have same configuration (CPU module, power supply module,
network module, and other modules). Even after an error occurs in one of the two system, the other
system takes over the control of the entire system. For details, refer to "Redundant system" of the
following manual.
MELSEC iQ-R Module Configuration Manual
Relay station A station that includes two or more network modules. Transient transmission is performed 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 CC-Link IE Field Network
by cyclic transmission. This station responds to a transient transmission request from another station.
Remote head module An abbreviation for the RJ72GF15-T2 CC-Link IE Field Network remote head module
Remote I/O station A station that exchanges I/O signals (bit data) with the master station of CC-Link IE Field Network by
cyclic transmission
Remote input (RX) Bit data input from a slave station to the master station of CC-Link IE Field Network (For some areas in
a local station, data are input in the opposite direction.)
Remote output (RY) Bit data output from the master station to a slave station of CC-Link IE Field Network (For some areas in
a local station, data are output in the opposite direction.)
