Description
A power supply module used for a redundant configuration of power supplies.
This module is used together with a redundant power supply base unit, to build a redundant power
supply system.
A system that has two power supply modules on a base unit. Even if one power supply module
has failed, operation can be continued with the other power supply module.
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. ( Page 30 Redundant
system)
A station that includes two or more network modules. Data are passed through this station to
stations on other networks.
The abbreviation for RJ72GF15-T2 CC-Link IE Field Network remote head modules
A generic term for the R04CPU, R08CPU, R16CPU, R32CPU, and R120CPU
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))
The abbreviation for the MELSEC iQ-R series extension base unit
A generic term for the R08SFCPU, R16SFCPU, R32SFCPU, and R120SFCPU.
This module is used with a safety function module as a pair, and performs both standard control
and safety control.
Another term for the R6SFM.
This module is used with a Safety CPU as a pair and performs safety control. The module can
only be paired with the Safety CPU.
A system where a single CPU module controls I/O modules and intelligent function modules
A generic term for a local station, remote I/O station, remote device station, and intelligent device
station on CC-Link IE Field Network
A backup system in a redundant system
A system specified as a system A to distinguish between two systems connected with a tracking
cable.
When the two systems are simultaneously started up, the system A operates as a control system.
The system A is not changed to the system B even after system switching.
A system specified as a system B to distinguish between two systems connected with a tracking
cable.
When the two systems are simultaneously started up, the system B operates as a standby
system. The system B is not changed to the system A even after system switching.
A function which switches the systems between the control system and the standby system to
continue operation of the redundant system when a failure or an error occurs in the control system
An optical fiber cable used to connect two redundant function modules in a redundant system
Description
Version information to determine the Safety CPU and safety function module used as a pair
Communication service that performs send/receive processing in the safety layer of the safety
communication protocol
Machine control by safety programs and safety data communications. When an error occurs, the
machine in operation is securely stopped.
A device that can be used in safety programs
A program that performs safety control
A generic term for the MELSEC iQ-R series modules that perform safety control (such as a Safety
CPU, safety function module, CC-Link IE Field Network remote I/O module (with safety functions))
Communications other than safety communications, such as cyclic transmission and transient
transmission of CC-Link IE Field Network
Machine control by standard programs and standard data communications. Programmable
controllers other than the safety programmable controller perform only standard control. (This
term is used to distinguish from safety control.)
A generic term for MELSEC iQ-R series CPU modules (other than Safety CPU) that perform
standard control (This term is used to distinguish from the Safety CPU.)
A device (X, Y, M, D, or others) in a CPU module. (Safety devices are excluded.) This device can
be used only in standard programs. (This term is used to distinguish from a safety device.)
