Description
Memory in an intelligent function module to store data such as setting values and monitor values.
For CPU modules, it refers to memory to store data such as setting values and monitor values of the Ethernet function, or data
used for data communication of the multiple CPU system function.
A group of devices and switching hubs compatible with CC-Link IE TSN, ranked according to the functions and performance by
the CC-Link Partner Association.
For CC-Link IE TSN Class, refer to the CC-Link IE TSN Installation Manual (BAP-C3007ENG-001) published by the CC-Link
Partner Association.
This protocol is used to perform communications by using the time sharing method defined by IEEE 802.1AS or IEEE 1588 for
time synchronization.
This protocol is used to perform communications by using the time sharing method defined by IEEE 802.1AS and time-managed
polling method for time synchronization.
Supporting this protocol version mitigates restrictions when "Mixture of CC-Link IE TSN Class B/A or CC-Link IE TSN Class A
Only" is set in the system configuration, and increases the number of connectable devices.
An instruction that simplifies programming for using functions of intelligent function modules
A memory of a CPU module to store data. Devices such as X, Y, M, D, and others are provided depending on the intended use.
A station other than a master station: a local station and a remote station
A tool used for setting up programmable controllers, programming, debugging, and maintenance
A CC-Link IE TSN Class A switching hub authorized by the CC-Link Partner Association ( Page 68 Switching Hub
(RJ71GN11-T2 Only))
A label that is valid for all the program data when multiple program data are created in the project. There are two types of global
label: a module specific label (module label), which is generated automatically by GX Works3, and an optional label, which can be
created for any specified device.
A module that has functions other than an input or output, such as an A/D converter module and D/A converter module
A device (RX, RY, RWr, RWw, LB, or LW) in a module on CC-Link IE TSN.
Processing of data transfer between link devices of the network module and CPU module devices. Link refresh is performed in
"END processing" of the sequence scan of the CPU module.
A station that performs cyclic transmission and transient transmission with the master station and other local stations
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.
A label that represents one of memory areas (I/O signals and buffer memory areas) specific to each module in a given character
string. For the module used, GX Works3 automatically generates this label, which can be used as a global label.
A filter function that selects whether to send cyclic data of multicast mode received by the own station to the subsequent stations.
Setting parameters for this function are not required because the master station automatically sets the parameters according to
the system configuration.
A communication mode used to send cyclic data to multiple stations
A station in which multiple network modules are mounted on one programmable controller to relay data link to other stations
A station that exchanges I/O signals (bit data) and I/O data (word data) with another station by cyclic transmission. This station
can perform transient transmission.
A function to exchange safety data between safety stations on the same network
A connection established for safety communication
Data exchanged through safety communication
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.
Communications other than safety communications, such as cyclic transmission and transient transmission of CC-Link IE TSN
A CC-Link IE TSN Class B switching hub authorized by the CC-Link Partner Association ( Page 68 Switching Hub
(RJ71GN11-T2 Only))
A communication mode used to send cyclic data to one station
