Description
A token to send data over a network of CC-Link IE
Memory in an intelligent function module for storing data such as setting values and monitored values.
When integrated into the CPU module, this memory refers to a memory for storing data such as setting
values and monitored values of the Ethernet function, and data used for data communication of the
multiple CPU system function.
A generic term for CC-Link IE Controller Network and CC-Link IE Field Network
A generic term for the RJ71GP21-SX CC-Link IE Controller Network module, the RJ71GP21S-SX CC-
Link IE Controller Network module, and the following modules when the CC-Link IE Controller Network
function is used:
• RJ71EN71
• RnENCPU
A generic term for the RJ71GF11-T2 CC-Link IE Field Network master/local module and the following
modules when the CC-Link IE Field Network function is used:
• RJ71EN71
• RnENCPU
A generic term for the CC-Link IE Controller Network-equipped module and CC-Link IE Field Network-
equipped master/local module
A CPU module that controls connected I/O modules and intelligent function modules.
The multiple CPU system allows the user to assign this control to any CPU module on a module-by-
module basis.
A station that controls the entire network on CC-Link IE Controller Network. This station can perform
cyclic transmission and transient transmission with all stations. Only one master station can be used in
a network.
A system that takes control and performs network communications in a redundant system
A generic term for the MELSEC iQ-R series CPU modules
A built-in Ethernet port part of the CPU module (CPU part for the RnENCPU) ( Page 23 CPU
Module)
A function by which data are periodically exchanged among stations on the same network using link
devices on CC-Link IE
A generic term for cyclic transmission and transient transmission
An instruction for using the functions of a module
A device (X, Y, M, D, or others) in a CPU module
A generic term for a device which supports iQ Sensor Solution
For details on iQ Sensor Solution, refer to the following.
 iQ Sensor Solution Reference Manual
A process of stopping data link if a data link error occurs
Another term for the software package for the MELSEC programmable controllers
An abbreviation for the NZ2GF-ETB CC-Link IE Field Network Ethernet adapter module
A generic term for the devices supporting IP communication (such as personal computers)
A generic term for the following modules when the Ethernet function is used:
• RJ71EN71
• CPU module
A generic term for the personal computer and other Ethernet-equipped modules connected over
Ethernet for data communications
An abbreviation for File Transfer Protocol. This protocol is used to transfer data files over a network.
A label that is valid for all the program data when multiple program data are created in the project.
There are two types of global label: a module specific label (module label), which is generated
automatically by GX Works3, and an optional label, which can be created for any specified device.
An abbreviation for the LJ72GF15-T2 CC-Link IE Field Network head module
A station that controls the communications using link devices on CC-Link IE Controller Network. Up to
two I/O master stations can be set for one network (block 1 and block 2), regardless of the status of
control or normal 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
and also issues a transient transmission request to another station.
A module that has functions other than input and output, such as an A/D converter module and D/A
converter module
