Description
A memory in an intelligent function module, where data (such as setting values and monitoring values) exchanged with a
Safety CPU are stored
A high-speed and large-capacity open field network that is based on Ethernet (1000BASE-T)
A function by which data are periodically exchanged among stations on the same network using link devices (RX, RY,
RWw, and RWr)
A function that diagnoses contacts including external devices using OFF pulses
A generic term for cyclic transmission and transient transmission
An instruction that simplifies programming for using functions of intelligent function modules
A process of stopping data link if a data link error occurs
The product name of the software package for the MELSEC programmable controllers
The state of having set the minimum required parameters on the module, so that data communication with external
devices is possible
Word data that indicates the operating status and data link status of a module on CC-Link IE Field Network
Bit data that indicates the operating status and data link status of a module on CC-Link IE Field Network
A station that performs cyclic transmission and transient transmission with the master station and other local stations.
The station is controlled by programs in the Safety CPU or other equivalent modules on the station.
A function that, upon occurrence of an error, disconnects only the station where the error occurred, and maintains data
links only with the normally operating stations. Data links can be maintained even with normally operating stations
connected past the faulty station whose line was disconnected.
A station that controls the entire network. This station can perform cyclic transmission and transient transmission with all
stations. Only one master station can be used in a network.
An abbreviation for the CC-Link IE Field Network master/local module
An abbreviation for a normally closed contact. The contact opens with an operation (such as switch operation).
An abbreviation for a normally open contact. The contact closes with an operation (such as switch operation).
An abbreviation for ZP.REMFR.
Buffer memory in a remote device station and intelligent device station
A station that exchanges I/O signals (bit data) and I/O data (word data) with another station by cyclic transmission. This
station responds to a transient transmission request from another station.
Bit data input from a slave station to the master station (For some areas in a local station, data are input in the opposite
direction.)
 User's manual for the master/local module used
Bit data output from the master station to a slave station (For some areas in a local station, data are output in the opposite
direction.)
 User's manual for the master/local module used
Word data input from a slave station to the master station (For some areas in a local station, data are input in the opposite
direction.)
 User's manual for the master/local module used
Word data output from the master station to a slave station (For some areas in a local station, data are output in the
opposite direction.)
 User's manual for the master/local module used
An abbreviation for ZP.REMTO.
A station reserved for future use. This station is not actually connected, but counted as a connected station
A safety level specified in EN954-1 The safety level is divided into 5 levels (B, 1 to 4).
A device that can be used in safety programs
A function provided to protect a person from the hazards of machines
A generic term for the NZ2GFS12A2-16DTE and the NZ2GFS12A2-14DT
A safety device (safety input) that can be used in safety programs
A safety device (safety output) that can be used in safety programs
A remote station to perform safety communications
A output in which a current flows from the load into the output terminal when the output transistor turns on
A generic term for stations other than a master station: local station, remote I/O station, remote device station, and
intelligent device station
A output in which a current flows out from the output terminal to the load when the output transistor turns on
