TERMS
Unless otherwise specified, this manual uses the following terms.
Term Description
CC-Link IE Field Network A high-speed and large-capacity open field network that is based on Ethernet (1000BASE-T)
CommDTM(Communication DTM) A software module used to configure the communication setting required for communications between a personal
computer and field devices via the IO-Link master.
CPU module A generic term for the MELSEC iQ-R series CPU module, MELSEC-Q series CPU module, and MELSEC-L series CPU
module
CQ input signal An external input signal input by the IO-Link master via the CQ line when the operation mode is the SIO (sink input)
mode
CQ output signal An external output signal output by the IO-Link master via the CQ line when the operation mode is the SIO (source
output) mode
Cyclic transmission A function by which data are periodically exchanged among master stations and other stations on the same system
using link devices
Data link A generic term for cyclic transmission and transient transmission
Dedicated instruction An instruction for using the functions of a module
Device DTM A software module used to configure the parameter settings of field devices or monitor field devices.
DI signal An external input signal input by the IO-Link master via the DI line when the operation mode is the IO-Link (sink input)
mode
Disconnection A process of stopping data link if a data link error occurs
DTM catalog By registering the M_CommDTM-IOLink, the DTM catalog displays a list of available DTMs.
DTM(Device Type Manager) A software module used to configure the communication settings, set parameters of field devices, or monitor field
devices when an FDT frame application is used.
Engineering tool Another term for the software package for the MELSEC programmable controllers
FDC An abbreviation for the MELSOFT FieldDeviceConfigurator
FDT frame application A generic term for applications to use a DTM. An FDT frame application complies with the FDT/DTM open standard
FDT(Field Device Tool) Software standard specifications for management, maintenance, adjustment, and development of field devices
Global label 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.
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 can perform transient transmission as well. This station responds to a transient transmission request from
another station and also issues a transient transmission request to another station.
IO-Link device An external device that supports IO-Link
IO-Link master Performs communications with the IO-Link sensor and actuator in the IO-Link module
IO-Link mode A generic term for the IO-Link (standard) mode and IO-Link (sink input) mode
IO-Link module An abbreviation for the CC-Link IE Field Network remote IO-Link module
IODD DTM Configurator A software program that operates the IODD file (device description file of IO-Link) as the Device DTM.
IODD(IO-Link Device Description) This description consists of the XML file containing the IO-Link device information and the image file in the png format.
This description is supplied from a manufacturer of an IO-Link device.
ISDU Data read from or written to parameters of IO-Link devices
Label A label that represents a device in a given character string
Link device A device (RX, RY, RWr, or RWw) in a module on CC-Link IE Field Network
Link special register (SW) Information that indicates the operating status and data link status of a module on CC-Link IE Field Network in units of
16 bits (1 word)
Link special relay (SB) Bit data that indicates the operating status and data link status of a module on CC-Link IE Field Network
Local station A station that performs cyclic transmission and transient transmission with the master station and other local stations.
M_CommDTM-IOLink CommDTM that supports communications with the IO-Link device via the IO-Link module.
Master station 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.
Master/local module An abbreviation for the CC-Link IE Field Network master/local module
MELSOFT FieldDeviceConfigurator Configuration Tool, which is developed by Mitsubishi Electric Corporation.
MELSOFT FieldDeviceConfigurator complies with the FDT/DTM open standard and is used for parameter settings,
maintenance, and adjustment of field devices as an FDT frame application.
Module label 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.
