5.1
Function List
The following table explains the function list of the CC-Link IE Field Network board.
Cyclic transmission
Transient transmission

Communication
with other
stations
Communication by RX and
RY
I/O data in bit units is communicated between the own station and other
stations.
Communication by RWw and
RWr
I/O data in word units is communicated between the own station and other
stations.
Link refresh
Transfer between the link device of the CC-Link IE Field Network board and
the device of the driver is performed automatically.
Mode selection for cyclic transmission
This mode is selected for optimizing the performance of cyclic transmission
based on the cyclic transmission and transient transmission frequency.
The mode can be selected from "Online (Normal mode)" and "Online (High-
speed mode)".
Link scan mode setting
Constant link scan setting can be selected to execute the link scan at a
constant time interval.

setting
Assurance of cyclic data integrity
The cyclic data integrity is assured in units of 32 bits or station-based units.

Input status setting for data link faulty station
Select whether the input data from another station where the data link error
occurred is cleared or held.

setting
Cyclic transmission stop and restart
During debugging and other operations, cyclic transmission is stopped (Data
reception from the slave station and data transmission from own stations are
stopped). Also, the stopped cyclic transmission is restarted.
Transient transmission is not stopped.

Communication by MELSEC data link library
function
Communicate with other station's programmable controller by MELSEC data
link library function.
• Device reading and writing of other station's programmable controller
• Remote operation to other station's programmable controller
• Data reading and writing of an intelligent device station

Communication on the
same network
Seamless transmission with different networks
Setting the routing parameters beforehand also enables transient
transmission to stations in different networks. Communication is also possible
with the CC-Link IE Controller Network, and MELSECNET/H.
