Description
A token to send data over a network
A memory in an intelligent function module, where data (such as setting values and monitoring values) are
stored. When using the CPU module, the memory is indicated for storing data (such as setting values and
monitored values) of the Ethernet function and data used for data communication of the multiple CPU function.
A field network system where data processing for control and information can be simultaneously performed at
high speed.
A generic term for the RJ71GP21-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 G.CCPASET and GP.CCPASET
A CPU module that controls connected I/O modules and intelligent function modules. In a multiple CPU system,
there are multiple CPU modules and each connected module can be controlled by a different CPU module.
A system that takes control and performs network communications in a redundant system
A generic term for the MELSEC iQ-R series CPU module
A built-in Ethernet port part of the CPU module (CPU part for the RnENCPU) ( MELSEC iQ-R Ethernet/CC-
Link IE User's Manual (Startup))
A function by which data are periodically exchanged among stations on the network using link devices
A generic term for cyclic transmission and transient transmission
An instruction for using functions of the module
A device (X, Y, M, D, or others) in a CPU module
A process of stopping data link if a data link error occurs
The product name of the software package for the MELSEC programmable controllers
The 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 label that is enabled for all program data when creating multiple program data in the project. There are two
types of global labels: module label that is automatically generated by GX Works3 and label that can be created
for the any of the specified devices.
The abbreviation for the LJ72GF15-T2 CC-Link IE Field Network head module
A station that exchanges I/O signals (bit data) and I/O data (word data) with another 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.
A module that has functions other than input and output, such as an A/D converter module and D/A converter
module
A label that represents a device in a given character string
A device (RX, RY, RWr, or RWw) in a module on CC-Link IE Field Network
Automatic data transfer between a link device of the master/local module and a device in a CPU module
Time required for all the stations on the network to transmit data. The link scan time depends on data volume and
the number of transient transmission requests.
Word data that indicates the operating status and data link status of a module on CC-Link IE Field Network
Bit data that indicates the operating status and data link status of a module on CC-Link IE Field Network
A station that performs cyclic transmission and transient transmission with the master station and other local
stations
A station that controls the entire network in the network where a master station and submaster station are
connected. Only one master station can be used in a network.
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.
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
