Restriction of firmware version
Combination of the master station and local stations
For the FX5-CCLGN-MS, when using the CC-Link IE TSN Protocol version 2.0 (mixture of CC-Link IE TSN Class B/A),
perform the firmware update on modules with "1.002" or earlier to update to "1.010" or later before use.
However, if the CC-Link IE TSN Protocol version 2.0 (mixture of CC-Link IE TSN Class B/A) is used and any CC-Link IE TSN
Class A device station that does not support the CC-Link IE TSN Protocol version 2.0 is included in the network, operation
reverts to the CC-Link IE TSN Protocol version 1.0, and the restrictions of the connection configuration apply accordingly.
In addition, if a station that does not support the CC-Link IE TSN Protocol version 2.0 is connected after performing a data link
with the CC-Link IE TSN Protocol version 2.0 (mixture of CC-Link IE TSN Class B/A), that station does not perform a data link.
Devices connected to the same network
Do not connect the devices as described below. Doing so may cause the disconnection of all stations.
• A module on CC-Link IE TSN and a device having network types other than an Ethernet device (such as CC-Link IE
Controller Network and CC-Link IE Field Network) are connected to the same network.
• A module on CC-Link IE TSN and an Ethernet device (such as a personal computer), both of which are on different
networks, are connected to one industrial switch.
Adding a device station with no IP address setting
In a line topology, do not connect a device station with no IP address setting at a place other than the end of the network. A
data link may not be performed in the device stations after the device station with no IP address setting.
CC-Link IE TSN/CC-Link IE Field diagnostics
If operations such as the following are performed, the actual network configuration and the network map of the CC-Link IE
TSN/CC-Link IE Field diagnostics may be a mismatch.
The actual network configuration and network map can be matched by executing the network map update of
the CC-Link IE TSN/CC-Link IE Field diagnostics. ( Page 201 CC-Link IE TSN/CC-Link IE Field
diagnostics)
Calculation of the total cyclic data size
The following shows the calculation formula of the total cyclic data size. The part of the variable surrounded by double quotes
(" ") is the setting value of "Network Configuration Settings" under "Basic Settings".
Total cyclic data size = 256 + (146  Number of local stations) + (106  Number of remote stations) + (Number of "RX setting"
points  8) + (Number of "RWr setting" points  2) [byte]
Network
configuration
Operation
Star topology • Powering off and on a device station or industrial switch
• Connecting/disconnecting an Ethernet cable connected to the industrial switch
• Disconnecting an Ethernet cable from a device station and connecting it to another device station or an industrial switch
• Disconnecting more than nine stations, or half the number of device stations or more in the system
• Changing the network topology when adding a device station
Line topology • Simultaneously powering off/on multiple stations
• Simultaneously connecting/disconnecting Ethernet cables to/from multiple stations (When a data link faulty station returns, a data
link error will occur in all the stations.)
• Disconnecting more than nine stations, or half the number of device stations or more in the system
• Changing the network topology when adding a device station
