Description
A label that represents one of memory areas (I/O signals and buffer memory areas) specific to each module in a
given character string. GX Works3 automatically generates this label, which can be used as a global label.
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)
A system that has switched to control system from standby system after system switching
A system that has switched to standby system from control system after system switching
A generic term for the R08PCPU, R16PCPU, R32PCPU, and R120PCPU
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.
The abbreviation for Reliability, Availability, and Serviceability. This term refers to usability of automated
equipment.
A generic term for the JP.READ and GP.READ
A generic term for the JP.RECV and GP.RECV
A generic term for the G.RECVS and Z.RECVS
Another term for the R6RFM.
This module is used with the Process CPU (redundant mode) as a pair and configures a 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
A station that includes two or more network modules. Data are passed through this station to stations on other
networks.
A generic term for the JP.REMFR and ZP.REMFR
The abbreviation for the JP.REMFRD.
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.
The abbreviation for the RJ72GF15-T2 CC-Link IE Field Network remote head module
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.)
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.)
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.)
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.)
A generic term for the JP.REMTO and ZP.REMTO
The abbreviation for the JP.REMTOD.
A generic term for the J.REQ, JP.REQ, G.REQ, and GP.REQ
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
A generic term for the J.RIRD, JP.RIRD, G.RIRD, and GP.RIRD
A generic term for the J.RIWT, JP.RIWT, G.RIWT, and GP.RIWT
A generic term for the R04ENCPU, R08ENCPU, R16ENCPU, R32ENCPU, and R120ENCPU
The left side (CPU part) of the RnENCPU ( MELSEC iQ-R Ethernet/CC-Link IE User's Manual (Startup))
The right side (network part) of the RnENCPU ( MELSEC iQ-R Ethernet/CC-Link IE User's Manual (Startup))
A process of selecting paths for communication with other networks. There are two types of routing: dynamic
routing that auto-selects the communication routes, and static routing where communication routes are arbitrarily
set.
A function to exchange safety data between safety stations on the same network
A connection established for safety communications
A generic term for the R08SFCPU, R16SFCPU, R32SFCPU, and R120SFCPU
Data exchanged through safety communications
