Description
A system that has switched to control system from standby system after system switching.
A generic term for the GP.OPEN and ZP.OPEN
A generic term for the partner products with built-in EZSocket that supports a redundant system. For
communications with an OPS, use "OPS Connection Module" of "Module List" in "External Device
Configuration" under "Basic Settings".
A function of GX Works3.
This function sets protocols appropriate to each external device and reads/writes protocol setting data.
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.
A generic term for the R00CPU, R01CPU, R02CPU, R04CPU, R04ENCPU, R08CPU, R08ENCPU,
R16CPU, R16ENCPU, R32CPU, R32ENCPU, R120CPU, R120ENCPU
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) or SIL2 Process CPU 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. Transient transmission is performed through this
station to stations on other networks
The abbreviation for the RJ72GF15-T2 CC-Link IE Field Network remote head module
A generic term for the J.REQ, JP.REQ, G.REQ, and GP.REQ
A generic term for the R04ENCPU, R08ENCPU, R16ENCPU, R32ENCPU, and R120ENCPU
A module on the left-hand side of the RnENCPU ( MELSEC iQ-R Ethernet/CC-Link IE User's
Manual (Startup))
A module on the right-hand side 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 generic term for the R08SFCPU, R16SFCPU, R32SFCPU, and R120SFCPU
Communication that allows users to access a different kind of networks without having to consider the
differences as if data were exchanged within one single network.
A generic term for the JP.SEND and GP.SEND
Another name for the R6PSFM.
This module is used with the SIL2 Process CPU as a pair and performs safety control. The module can
only be paired with the SIL2 Process CPU.
A generic term for the R08PSFCPU, R16PSFCPU, R32PSFCPU, and R120PSFCPU
This module is used with a SIL2 function module as a pair, and performs both standard control and
safety control. This module is also used with a redundant function module as a pair and configures a
redundant system.
The 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.
A generic term for the JP.SREAD and GP.SREAD
A backup system in a redundant system
A number used to logically divide one network into multiple subnetworks and manage them easily. The
following Ethernet network systems can be configured:
• A small-scale Ethernet network system in which multiple network devices are connected.
• A medium- or large-scale network system in which multiple small-scale network systems are
connected via routers or other network communication devices.
A generic term for the JP.SWRITE and GP.SWRITE
A system that is set as system A to distinguish two systems, which are connected with two tracking
cables. When the two systems start up at the same time, this system will be a control system. System
switching does not affect the system A/B setting.
