Description
A device that can be used in safety programs
Another name for the R6SFM
A label that can be used in safety programs
A generic term for a station that performs safety communications and standard communications
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.
An operation mode of the I/O module and the intelligent function module to perform safety input and output at the
SIL2 level. For details on the SIL2 mode, refer to the following.
 Manuals for the I/O module or the intelligent function module used
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.
A generic term for the J.SINFSTRD, JP.SINFSTRD, G.SINFSTRD, and GP.SINFSTRD
A generic term for the J.SINFTYRD, JP.SINFTYRD, G.SINFTYRD, and GP.SINFTYRD
A generic term for a local station, remote I/O station, remote device station, and intelligent device station
A generic term for the J.SLMPREQ, JP.SLMPREQ, G.SLMPREQ, and GP.SLMPREQ
A generic term for the JP.SREAD and GP.SREAD
A generic term for cyclic transmission and transient transmission
A generic term for a station that performs standard communications
A label that can be used in both programs and safety programs. This label is used to pass device data from
safety programs to programs.
A backup system in a redundant system
A station that monitors the status of a master operating station in the network where a master station and
submaster station are connected. Only one master station can be used in a network.
A station that serves as a master station to control the entire network if the master station is disconnected. Only
one master station can be used in a network.
A generic term for the JP.SWRITE and GP.SWRITE
A system that is set as the 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.
A system that is set as the 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.
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
A function of communication with another station, which is used when requested by a dedicated instruction or the
engineering tool
A generic term for the G.UINI, GP.UINI, Z.UINI, and ZP.UINI
A generic term for the JP.WRITE and GP.WRITE
