The following terms are used to explain a safety programmable controller system using the Safety CPU.
Predefined protocol support function
A function of GX Works3.
This function sets protocols appropriate to each external device and reads/writes protocol setting data.
Process CPU
A generic term for the R08PCPU, R16PCPU, R32PCPU, and R120PCPU
Programmable controller CPU
A generic term for the R04CPU, R04ENCPU, R08CPU, R08ENCPU, R16CPU, R16ENCPU, R32CPU, R32ENCPU,
R120CPU, and R120ENCPU
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.
Remote head module
The abbreviation for the RJ72GF15-T2 CC-Link IE Field Network remote head module
Request message
A processing request message sent from external devices to SLMP-compatible devices
Response message
A processing result message sent from SLMP-compatible devices in response to the request message
RnCPU
A generic term for the R04CPU, R08CPU, R16CPU, R32CPU, and R120CPU
RnENCPU
A generic term for the R04ENCPU, R08ENCPU, R16ENCPU, R32ENCPU, and R120ENCPU
RnENCPU (network part)
The right side (network part) of the RnENCPU (
MELSEC iQ-R Ethernet/CC-Link IE User's Manual (Startup))
RnPCPU
A generic term for the R08PCPU, R16PCPU, R32PCPU, and R120PCPU
Safety CPU
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 and safety control.
Safety function module
Another term for the R6SFM.
This module is used with the Safety CPU as a pair and performs safety control. The module can only be paired with the
Safety CPU.
Separate mode
A mode for system maintenance in a redundant system. This mode can maintain a redundant system without stopping
control while the system is running.
SFC
The abbreviation for the sequential function chart
SLMP
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.
SLMP-compatible device
A generic term for the devices of the Mitsubishi Electric product that can transfer SLMP messages (Ethernet adapter
module and Ethernet-equipped module)
ST language
The abbreviation for the structured text language
Standby system
A backup system in a redundant system
System A
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.
System B
A system that is set as system B 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 standby system. System switching does not
affect the system A/B setting.
Temperature input module
A generic term for the MELSEC iQ-R series channel isolated thermocouple input module and channel isolated RTD
input module
Term
Description
Safety cycle processing
Processing of safety input/output and safety program
Safety control
Machine control by safety programs and safety data communications. When an error occurs, the machine in operation
is securely stopped.
Safety communications
Communication service that performs send/receive processing in the safety layer of the safety communication protocol
Safety device
A device that can be used in safety programs (
MELSEC iQ-R CPU Module User's Manual (Application))
Safety program
A program for performing safety control
Safety label
A generic term for the safety global label, safety local label, and standard/safety shared label (
MELSEC iQ-R
Programming Manual (Program Design))
Standard CPU
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.)
Standard control
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.)
Standard communications
Communications other than safety communications, such as cyclic transmission and transient transmission of CC-Link
IE Field Network
Standard device
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.)
Standard program
A program that performs sequence control. (Safety programs are excluded.) (This term is used to distinguish from a
safety program.)
