A station reserved for future use. This station is not actually connected, but counted as a
connected station.
A function by which data are periodically exchanged among stations on the same network
using link devices (RX, RY, RWw, and RWr)
A function of communication with another station, which is used when requested by a
dedicated instruction or GX Works2
Generic term for cyclic transmission and transient transmission
An instruction that simplifies programming for using functions of intelligent function modules
A dedicated instruction used for transient transmission with another station.
This instruction allows a master/local module to communicate with programmable controllers
on the same network (CC-Link IE Field Network) and on other networks (Ethernet, CC-Link IE
Controller Network, and MELSECNET/H).
Process of restarting data link when a station recovers from an error
A process of stopping data link if a data link error occurs
A device (X, Y, M, D, or others) in a CPU module
A device (RX, RY, RWr, or RWw) in a module on CC-Link IE Field Network
Bit data input from a slave station to the master station.
Refer to Section 8.3.1.
Bit data output from the master station to a slave station.
Refer to Section 8.3.1.
Word data input from a slave station to the master station.
Refer to Section 8.3.1.
Word data output from the master station to a slave station.
Refer to Section 8.3.1.
Bit data that indicates the operating status and data link status of 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
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.
Data transfer between a link device in a module on CC-Link IE Field Network and a device in a
CPU module. Link refresh is performed in the END processing of the CPU module's sequence
scan.
A token to send data over a network
A memory in an intelligent function module, where data (such as setting values and monitoring
values) exchanged with a CPU module are stored
An address that indicates the storage location of data assigned to the buffer memory in an
intelligent function module
The abbreviation for Reliability, Availability, and Serviceability. This term refers to usability of
automated equipment.
