Description
A mode used to perform high-speed communications in a system consisting of a master station and
remote I/O station(s) only
A station that exchanges I/O signals (bit data) with the master station by cyclic transmission This station
cannot perform transient transmission.
Bit data input from a slave station to the master station (For some areas in a local station, data are input
in the opposite direction.)
A mode used to configure a system only with a master station and Ver.1-compatible slave station.
Data can be communicated with all stations (remote I/O station, remote device station, local station,
intelligent device station, and standby master station) in a CC-Link system.
A mode used to configure a system containing master stations and Ver.2-compatible slave stations or to
add Ver.2-compatible slave stations in future.
Data can be communicated with all stations (remote I/O station, remote device station, local station,
intelligent device station, and standby master station) in a CC-Link system.
Compared to the remote net Ver.1 mode, the number of cyclic points per station is increased from 128
to 896 for RX/RY, and from 16 to 128 for RWr/RWw.
Bit data output from the master station to a slave station (For some areas in a local station, data are
output in the opposite direction.)
Word data input from a slave station to the master station (For some areas in a local station, data are
input in the opposite direction.)
Word data output from the master station to a slave station (For some areas in a local station, data are
output in the opposite direction.)
A generic term for a remote I/O station and a remote device station
A process of restarting data link when a station recovers from an error
A generic term for a remote I/O station, remote device station, local station, intelligent device station,
and standby master station
A backup system in a redundant system
A function which switches the systems between the control system and the standby system to continue
operation of the redundant system when a failure or an error occurs in the control system
A function of communication with another station, which is used when requested by a dedicated
instruction or the engineering tool
A slave station that supports the remote net Ver.1 mode or remote device net Ver.1 mode
A slave station that supports the remote net Ver.2 mode or remote device net Ver.2 mode
