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)

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.

• 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.

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.

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.

Data flow of cyclic transmission
The following describes the data flow of cyclic transmission.
■Basic operation
The master station sends a request to all slave stations (including Ethernet devices within the same network address).
After receiving responses from all slave stations set with parameters, the master station starts sending another request. The
link scan refers to the operation from sending a request to sending another request and the link scan time refers to the time
required for a link scan. ( Page 28 Operation of the link scan)
7
Ls: Link scan
The master station sends a request to slave station 1 and slave station 2.
Slave station 1 sends a response to the master station.
Slave station 2 sends a response to the master station.
(1) Once the master station has received responses from slave station 1 and slave station 2, the master station starts sending another request.
• When the master station sends a request (starts cyclic transmission) to all slave stations, 'Cyclic
transmission status' (SM1536) turns on, and when the master station receives responses from each slave
station, a bit, that is corresponding to the station number of the slave stations which have sent a response,
of 'Cyclic transmission status of each station' (SD1536 to SD1539) turns on.
• When the master station starts cyclic transmission, if no response has been received from a slave station,
the applicable slave station is not detected as a faulty station. (The 'Data link status' (SM1540) does not turn
on.) In addition, the transmission status of CC-Link IE Field Network Basic diagnostics becomes "Unfixed".
• When slave stations are divided into groups, each of the groups performs the cyclic transmission. For the
data flow of group number setting, refer to the following.

If the master station is unable to receive a response from a slave station due to the power-off or cable disconnection of the
slave station, the master station waits for a response from the slave station within the timeout time set in the link scan settings.
If no response is received within the specified number of times for disconnection detection, the master station disconnects the
slave station.

(Slave station disconnection detection setting: Timeout time = 100ms, number of times = 3 times)
Ls: Link scan
The master station sends a request to slave station 1 and slave station 2.
Slave station 1 sends a response to the master station.
Slave station 2 sends a response to the master station.
(1) Slave station 2 cannot respond to the master station due to an error such as power-off or cable disconnection of the slave station.
(2) The master station waits for the response from slave station 2 until the timeout time runs out and then send a request to slave station 1 and slave station 2
because the master station cannot receive a response from slave station 2. Note that the link scan time is extended by the timeout time.
(3) The master station disconnect slave station 2 because the master station cannot receive a response from slave station 2 by the specified number of times
(three times) for the disconnection detection.
The following table lists the special relay and special register operations when a slave station which did not send a response
is disconnected.

'Cyclic transmission status' (SM1536) Remains turned on.
'Cyclic transmission status of each station' (SD1536 to

'Data link status' (SM1540) Turns off and on.
'Data link status of each station' (SD1540 to SD1543) The bit corresponding to the station number of the disconnected slave station is turned on
• If a timeout due to a failure of a slave device occurs, a timeout time will be equivalent to a link scan time. To
lessen the impact on communications with normal slave stations by transmission delay, adjust the timeout
time. ( Page 39 Link Scan Setting) For example, check the current link scan time (when all slave
stations normally operate) using the CC-Link IE Field Network Basic diagnostics, and then specify a value,
which is about five times as long as the link scan time, for timeout time. (When the current link scan time is
10ms, specify 50ms for the timeout time.)

• The link scan operates separately from the operation of programs.
• If the scan time is smaller than link scan time, link refresh is not performed until the master station receives
responses from all slave stations.
• The link scan time may increase five times longer than the normal time depending on the processing load or

Group number setting
(1)
(2)
Group No.1
Group No.2
This function divides slave stations into groups by setting a group number to each slave station and each of groups performs
the cyclic transmission.
By organizing groups separating slave stations with shorter response processing time from ones with longer response
processing time, the differences of the reference response times of each slave station does not badly affect the cyclic
transmission.
(1)The total number of occupied stations for one group is 16 maximum.
(2)Up to four groups can be organized.
Before using the group number setting, check the versions of the CPU module and the engineering tool. (
Page 58 Added and Enhanced Functions)
Note, however, there is no restriction for the R00CPU, R01CPU, and R02CPU.
How to organize groups
Organize groups considering the following.
■Dividing slave stations into groups
• Organizing two or more groups can configure a network with slave stations that occupy 17 or more stations in total.
• By dividing slave stations into groups with similar reference response time, the gap of the response time of each slave
station does not badly affect the cyclic transmission. For details on the reference response time, refer to manuals for slave
stations used. Link scan times vary from group to group. The link scan time of each group is affected by a slave station that
has the longest reference response time in a group. ( Page 31 Data flow of cyclic transmission)
■Merging slave stations into one group
• To perform cooperating operation between slave stations, merge them into the same group.
• When the line load is large, merging slave stations into the fewest number of groups as possible according to the number of
slave stations connected to the master station is recommended. For example, merge slave stations into one group if the
slave stations are 16 or less. When two or more groups are organized, the master station sends requests to each of them.
Since the packets of the cyclic transmissions performed for each group flow on the line, the more groups are organized, the
larger the line load becomes.

The following describes the data flow of cyclic transmission of when the group number setting is used.
■Basic operation
The master station sends requests, that vary from a group to group, to all salve stations. Although slave stations receive
multiple request messages from the master station, each slave station handles a request message for a group where each
slave stations belong to.
After receiving responses from all the slave stations in a group, the master station starts sending another request to the group.
For this reason, link scan times vary from group to group.
Since the link scan setting can be configured for each group, the setting can be according to response processing times of
each group. ( Page 39 Link Scan Setting)

Slave station 1 sends a response to the master station.
Slave station 2 sends a response to the master station.
The master station sends requests to slave station 3 that belongs to group 2.
Slave station 3 sends a response to the master station.

■Automatic detection of connected device
Actually connected slave stations are detected and reflected in the network configuration setting.
In the network configuration setting, communication settings such as IP addresses and subnet masks can be configured for
the detected slave stations.
Parameters that are inherent in the slave stations can also be read/written from/to the network configuration setting. (Some
slave stations do not support these features.)
Various settings of all slave stations can be configured in parameters of the master station (the settings do not need to be
configured in each individual slave station) and therefore the man-hour for the setting will be reduced.
Follow the operating procedure below to use the automatic detection of connected device.
1. Start up a new project in GX Works3/GX Works2 and execute the automatic detection of connected device.
2. Detected slave stations are reflected in the network configuration setting. Change the items such as the connection order
and numbers of occupied stations and set station numbers.
3. Configure IP addresses and subnet masks of slave stations in the network configuration setting. And then, reflect the
settings to the slave stations.
Select a module on the list of stations or the network map [Online] [Communication Setting Reflection of Slave
Station]
4. Parameters that are inherent in the slave stations can be read/written from/to the network configuration setting.
details on the parameters inherent in each slave station, refer to the manuals of the slave station used.

the column of "Read Value". To write parameters, select "Parameter write" from "Method selection", input data to the column of "Write
Value", and then click the [Execute] button.
Slave station settings in the network configuration setting must be configured after executing the automatic
detection of connected device.
If not, contents of setting items that have been already configured in the network configuration setting are
overwritten by ones detected by the automatic detection. Detected slave stations are reflected in the network
configuration setting in ascending order of MAC address and values such as the number of occupied stations

*1 Devices on Ethernet have a table of IP addresses and their corresponding MAC address, called the ARP cache. When a device on the
line is replaced with a device having the same IP address, the MAC address in the ARP cache becomes different from that of the
replaced device. This may cause incorrect data communications. The ARP cache is updated by resetting a device or after a certain time
has elapsed. The time varies depending on the device.
