CC-Link IE Field Network Basic is an factory automation network using the standard Ethernet.
Data is periodically communicated between the master station and slave stations using link devices (cyclic transmission).

Cost saving of the system
The CPU module with built-in Ethernet port is the master station of CC-Link IE Field Network Basic. Since a dedicated
network module is not used, the cost for the system can be reduced.
Using different protocols
CC-Link IE Field Network Basic can be used with other standard Ethernet protocols. Thus, a network system in which different
protocols such as FTP, HTTP, and SLMP coexist can be configured.
Moreover, a gateway is not required for communications with personal computers and other information devices.

The link scan time of cyclic transmission is increased by executing following functions:
• The built-in Ethernet functions such as FTP. socket communications, and SLMP communications
• Communications with other Ethernet devices on the same line
Use the built-in Ethernet function above or other Ethernet devices so that the system being used is not
affected. ( Page 47 When access to the CPU module is slow)

(1)
Configure the entire network of CC-Link IE Field Network Basic in the master station. To perform the cyclic transmission, set
an IP address and subnet mask to each slave station. Setting the information of the master station to each slave station is not
required.
In addition, since the devices are connected in star topology, there are no restrictions on the connection order or connection
position of devices. Thus, it is also easy to connect a new slave station.

4 PROCEDURES BEFORE OPERATION
This chapter describes the procedures before operation.
1. Configuring a network system
Configure a network system. ( Page 14 SYSTEM CONFIGURATION, Page 13 Wiring precautions)
2. Setting parameters of the master station
• IP address setting (such as IP address, subnet mask)
• CC-Link IEF Basic setting ( Page 34 Settings for the Master Station in MELSEC iQ-R/MELSEC iQ-F, Page 41
Settings for the Master Station in MELSEC-Q/L)
Actually connected devices can be detected by the automatic detection of connected device and reflected in
the network configuration setting. ( Page 36 Automatic detection of connected device)
In the network configuration setting, communication settings, such as IP addresses and subnet masks, and
writing/reading parameters that are inherent in the slave stations can also be performed to the slave stations.
(Some slave stations does not support these features.)
3. Configure the necessary settings of the slave station such as the IP address and subnet mask. (Manual for the slave
station used)
4. Write parameters to the CPU module on the master station. (Operating manual for the tool used)
5. Start up the slave stations.
6. Cyclic transmission starts if the CPU module on the master station is powered off and on or reset.
7. Diagnosing a network
Check the status of a network by executing the CC-Link IE Field Network Basic diagnostics. ( Page 43 CC-Link IE Field
Network Basic Diagnostics)
8. Programming
Create a program. For details, refer to the following.

4 PROCEDURES BEFORE OPERATION
Wiring precautions
• Place the Ethernet cables in a duct or clamp them. If not, dangling cable may swing or inadvertently be pulled, resulting in
damage to the module or cables or malfunction due to poor contact.
• Do not touch the core of the cable-side or module-side connector, and protect it from dirt or dust. If oil from your hand, dirt
or dust is attached to the core, it can increase transmission loss, arising a problem in data link.
• Check that the Ethernet cable is not disconnected or not shorted and there is no problem with the connector connection.
• Do not use Ethernet cables with broken latches. Doing so may cause the cable to unplug or malfunction.
• Hold the connector part when connecting and disconnecting the Ethernet cable. Pulling the cable connected to the module
may result in malfunction or damage to the module or cable.
• For connectors without Ethernet cable, attached connector cover should be placed to prevent foreign matter such as dirt or
dust.
• The maximum segment length of the Ethernet cable is 100m. However, the length may be shorter depending on the
operating environment of the cable. For details, contact the manufacturer of the cable used.
• The bending radius of the Ethernet cable is limited. For details, check the specifications of the Ethernet cable to be used.
• For a cascade connection, recommended number of levels is up to three. If connected four levels or more, a packet loss
caused by switching hubs is more likely to occur.

When the subnet mask is 255.255.255.0 and the network address is 192.168.3.
Use the same subnet mask value and do not assign the same IP address for each slave station.

Number of link points
Ex.
Master station
Slave station 3Slave station 1 Slave station 2
The number of link points per slave station is 64 points for RX/RY and 32 points for RWr/RWw. ( Page 8 Performance
Specifications)
However, by changing the number of occupied stations, RX/RY can be set to a maximum of 256 points in increments of 64
points and RWr/RWw can be set to a maximum of 128 points in increments of 32 points. For details on the number of
occupied stations (whether or not the number can be changed), refer to the manual for the slave station used.
If the number of link points for the slave station is changed, the assignment range and station number are changed.
• Slave station 1: 1 station occupied
• Slave station 2: 2 stations occupied
• Slave station 3: 4 stations occupied
The following table lists the number of link points.

Setting the number of link points for a slave station to 2 stations occupied means that two slave stations are
connected. Thus, if the number of link points is increased, the number of connectable slave stations per
network is decreased.
