Function Lists
Functions of the CC-Link IE controller network module are listed below.
(1) List of cyclic transmission functions
: Available, : Partially available, : N/A
* 1 Data of other stations and station No.65 and higher cannot be received.
* 2 Cyclic data are sent to or received from the stations whose their own send ranges are allocated to
LB/LW 0 to 3FFF in "LB/LW settings (1)".
* 3 There are restrictions on the number of settings for each module set in Refresh parameters.
Section 6.4.1 Refresh parameters
* 4 Direct access to the area from LB/LW4000 and higher is not allowed.

Communication by 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.

Additional LB/LW
setting
(LB/LW settings (2))
Without changing the assignments in LB/LW settings
(1), extends each station's send range.
Communication by 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.

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.
Cyclic
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.
Constant link scan
Keeps the link scan time to a preset time period.
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.
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.
Interlink transfer
Transfers link device (LB/LW) data of a network
module to another network module at a relay station.
Online
operation
Stop/restart of cyclic
transmission
Disables receiving data from other stations and
sending data of its own station in a case such as
debugging. (Transient transmission is not stopped.)
