Description
A target for motion control
A memory in an intelligent function module, where data (such as buffer memory setting values and monitoring
values) are stored.
A class classified by CC-Link Partner Association according to functions and performance of CC-Link IE TSN-
compatible devices and switching hubs.
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.
Testing 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,
there are multiple CPU modules and each connected module can be controlled by a different CPU module.
A function by which data are periodically exchanged among stations on the network using link 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 process of stopping data link if a data link error occurs
A CC-Link IE TSN Class A switching hub certified 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
The product name of the software package for the MELSEC programmable controllers
(Version 1.072A or later)
A module in the MELSEC iQ-F series that has functions other than input and output, such as a Motion 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.
A station that updates a link device in the Motion module
MR-J5-_G_(-RJ)/MR-J5W_-_G Servo amplifier series
MR-JET-_G Servo amplifier series
A communication mode in which cyclic data is sent to multiple stations.
Various data held by the CANopen-compatible device station.
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.
A station that includes two or more network modules. Data are passed through this station to stations on other
networks.
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.
An IP address reserved for special purposes, defined by RFC 6890. This IP address cannot be used when the
programmable controller is connected via the global IP network.
A station which is not actually connected. It is included as a station in the network when its all number is counted.
A process of restarting data link when a station recovers from an error
An abbreviation for 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.
