Description
A generic term for main base units, extension base units, and RQ extension base units
Memory in an intelligent function module for storing data such as setting values and monitored values.
A generic term for the CC-Link IE Controller Network-equipped module and CC-Link IE Field Network-
equipped master/local module
A system that controls a redundant system and performs network communications in a redundant
system
A generic term for the MELSEC iQ-R series, MELSEC-Q series, and MELSEC-L series CPU module
A function by which data are periodically exchanged among stations on the same network using link
devices
A generic term for cyclic transmission and transient transmission
An instruction for using the functions of a module
A device (X, Y, W, or others) in a CPU module and remote head module
A process of stopping data link if a data link error occurs
The product name of the software package for the MELSEC programmable controllers
A generic term for the devices supporting IP communication (such as personal computers)
A generic term for the RJ71EN71 (when the Ethernet function is used) and MELSEC iQ-R series CPU
module (when the Ethernet function is used)
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 the engineering tool, and an optional label, which can be created for any specified
device.
A generic term for the input module, output module, I/O combined module, and interrupt module
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 and also
issues a transient transmission request to another station.
A module that has functions other than input and output, such as an A/D converter module and D/A
converter module
A label that represents a device in a given character string
A device (RX, RY, RWr, or RWw) in a module on CC-Link IE Field Network
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
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 generic term for the RJ71GF11-T2, QJ71GF11-T2, QS0J71GF11-T2, LJ71GF11-T2 CC-Link IE Field
Network master/local module and the following modules when the CC-Link IE Field Network function is
used:
• RJ71EN71
• RnENCPU
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 generic term for the following modules:
• Ethernet interface module
• CC-Link IE Controller Network module
• Module on CC-Link IE Field Network
• MELSECNET/H network module
• MELSECNET/10 network module
• RnENCPU (network part)
A remote head module that has switched to control system from standby system after system switching
A remote head module that has switched to standby system from control system after system switching
The abbreviation for the MELSEC iQ-R series power supply module
The abbreviation for Reliability, Availability, and Serviceability. This term refers to the overall usability of
automated equipment.
