Description
Memory in an intelligent function module to store data such as setting values and monitor values.
A group of devices and switching hubs compatible with CC-Link IE TSN, classified 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.
Test performed for communications of a CC-Link or CC-Link IE product to ensure their high reliability.
For details, refer to the CC-Link Partner Association website. (www.cc-link.org)
A CPU module that controls connected I/O modules and intelligent function modules. In a multiple CPU system, a
control CPU is set for each module.
Processing from the start to completion of a sequence of cyclic transmission by all the stations in a single network. It is
performed "asynchronously" with the sequence scan of the CPU module.
A function by which data is periodically exchanged among stations on the network
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 process of stopping data link if a data link error occurs
A CC-Link IE TSN Class A switching hub authorized by CC-Link Partner Association
A label that is enabled for all program data when creating multiple program data 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 source device or station to synchronize clocks in the time synchronization via PTP (Precision Time Protocol)
The product name of the software package for the MELSEC programmable controllers
A module that has functions other than input and output, such as an A/D converter module and D/A converter module
A variable used in a program
A device (RX, RY, RWr, or RWw) in a module on CC-Link IE TSN
Processing of data transfer between link device of the Motion module and CPU module devices. Link refresh is
performed in "END processing" of the sequence scan of the CPU module.
Time required for all the stations on the network to transmit data. The link scan time depends on data volume and the
number of transient transmission requests.
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.
Software that performs the motion control in the Motion module
A device station that exchanges cyclic data by using slave labels through motion control
Another term for the RD78G(H)
Another term for the motion control station
MR-J5-_G_(-RJ) servo amplifier
MR-J5D_-_G_ servo amplifier
MR-J5W_-_G servo amplifier
A communication mode used to send cyclic data to multiple stations
Various data of a device station compatible with CANopen
A value that is assigned to devices or stations in a network to determine the grandmaster for time synchronization. The
smaller the value, the higher the priority.
Another term for the MELSEC iQ-R series Motion module (compatible with CC-Link IE TSN)
A station that relays data link to other station with mounting more than one network modules on one programmable
controller
