Communication using LB/LW
Allows each station to write data to its own send
range area of a link device (LB/LW) to send them
to all other stations on the network.

Communication using LX/LY
Used to exchange data between the I/O master
station that controls LX/LY and another station on
a one-to-one (1:1) basis.

Refresh
Link refresh
Allows automatic data transfer between the link
devices of the CC-Link IE Controller Network
module and CPU module devices.

Section 4.1.3
Direct access to link
devices
Directly reads from or writes to link devices
(LB/LW/LX/LY/SB/SW) of the CC-Link IE Controller
Network module from the sequence program.

Assurance of cyclic data integrity
Assures cyclic data integrity in units of 32 bits or
stations.

transmission
punctuality
assurance
Cyclic transmission
punctuality assurance
Keeps the link scan time constant by making each
station to send the specified number of transient
transmissions within one link scan.

Section 4.1.6
Constant link scan Keeps the link scan time to a preset time period.

Section 4.1.7
Group cyclic transmission
A Universal model QCPU can share cyclic data
only with stations in the same shared group. It
does not receive cyclic data from stations in a
different shared group. Stations without shared
group setting will share cyclic data with all stations.

Increase of send points by mounting
multiple network modules of the same
network No.
Increases send points by mounting multiple CC-
Link IE Controller Network modules of the same
network No. with one CPU module.

Reserved station specification
Used to reserve a station that will be connected to
the network in the future (although the station is
not actually connected at present, it must be
included in the total number of stations for the
network.) Reserved stations are not detected as
faulty.

Section 4.1.10
Interlink transmission
Transfers link device (LB/LW) data of a network
module to another network module at a relay
station.
