Description
The abbreviation for the RJ71GF11-T2 the CC-Link IE Field Network master/local module
A function that diagnoses contacts including external devices by outputting an off pulse from the test
pulse terminal when the input or output is on
Another term for the software package for the MELSEC programmable controllers
A station that performs cyclic transmission and transient transmission with the master station and
other local stations on the CC-Link IE Field Network
A station that controls the entire the CC-Link IE Field Network.
Only one master station can be used in a network.
This station can perform cyclic transmission and transient transmission with all stations on the CC-
Link IE Field Network.
A contact that is closed or in a conductive state, and opened by operation of the switch
A contact that is open or in a non-conductive state, and closed by operation of the switch
Refer to the description of NC.
Refer to the description of NO.
A safety level specified in ISO13849-1: 2006 (The safety level is classified into five levels, a to e.)
A station that exchanges I/O signals (bit data) with the master station by safety communications.
This station can be used in a safety system.
A station that exchanges I/O signals (bit data) and I/O data (word data) with another station by
transient transmission. This station responds to a transient transmission request from another
station. This station cannot be used in a safety system.
A station that exchanges I/O signals (bit data) with the master station by cyclic transmission. This
station cannot be used in a safety system.
The combination of the possibility and severity of harm (injury or illness) that may occur when
exposed to a hazard
Overall process comprising identification of the hazards of machines and risk evaluation
Remote register (read area for the CC-Link IE Field Network)
Remote register (write area for the CC-Link IE Field Network)
Remote input (for the CC-Link IE Field Network)
Remote output (for the CC-Link IE Field Network)
A generic term for the applications that are controlled by the safety programmable controller for
realizing the safety function
Communication service that performs send/receive processing in the safety layer of the safety
communication protocol
A component such as a fail-safe sensor and actuator
Machine control by safety programs and safety data communications. When an error occurs, the
machine in operation is securely stopped.
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.
This is a time inserted to activate safety input and output, as well as the safety program.
A function provided to protect a person from the hazards of machines
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.
A generic term for the signals that are input to the safety programmable controller for realizing the
safety function
Measures for reducing risk
A generic term for the signals that are output from the safety programmable controller for realizing
the safety function
A generic term for the MELSEC iQ-R series modules that perform safety control (such as a Safety
CPU, safety function module, or the CC-Link IE Field Network remote I/O module (with safety
functions))
The abbreviation for the NZ2GFSS2-32D and NZ2EXSS2-8TE CC-Link IE Field Network remote I/O
module (with safety functions)
