Description
Describes the details of hardware of the CPU module, including
performance specifications, wiring, installation, and maintenance.
Describes the basic knowledge required for program design, functions of
the CPU module, devices/labels, and parameters.
Describes the specifications of ladder, ST, FBD/LD, and SFC programs, and
labels.
Describes the specifications of instructions and functions that can be used
in programs.
Describes the Ethernet communication function of the CPU module built-in
and the Ethernet module.
Describes the FX5-ENET.
BACnet functions of the Ethernet module.
Describes methods for the device that is communicating with the CPU
module by SLMP to read and write the data of the CPU module.
Describes the system configuration, parameter settings, and online
operations of GX Works3.
Description
An MQTT server that mediates messages (MQTT broker)
A function by which data are periodically exchanged among stations on the same network using link
devices on CC-Link IE Field Network Basic.
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 device (RX, RY, RWr, or RWw) in a CPU module for the purpose of communicating with remote stations
Automatic data transfer between a user device and a link device.
The master station of CC-Link IE Field Network Basic sends requests to all remote stations. After receiving
responses from all the remote stations, the master station sends next requests. The time taken from when
requests are sent to when the next requests are started to send by the master station.
A station that controls the entire CC-Link IE Field Network Basic. Only one master station can be used in a
network.
Data to be exchanged between the sender (publisher) and receiver (subscriber)
A protocol capable of one-to-many asynchronous communications
The sender of a message is called a publisher, the receiver is called a subscriber, and an entity playing an
intermediate role is called a broker.
The term "publish" means "send", and "subscribe" means "receive".
Service quality to be provided on the network
QoS is classified into 0 to 2. The larger number indicates better quality and slower transfer speed.
An abbreviation for Reliability, Availability, and Serviceability. This term refers to usability of automated
equipment.
Bit data input from a remote station to the master station
Bit data output from the master station to a remote station
Word data input from a remote station to the master station
Word data output from the master station to a remote station
A station that performs cyclic transmission with the master station on CC-Link IE Field Network Basic. I/O
signals in units of bits and I/O data in units of words are exchanged.
This term refers to whether to save the latest message for each topic.
If a message could not be sent due to reasons such as client disconnection, the latest message is
delivered when the connection is established again.
A process of restarting data link when a station recovers from an error.
