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.
Network Operation
configuration
Star topology • Powering off and on a device station or switching hub
• Connecting/disconnecting an Ethernet cable connected to the switching hub
• Disconnecting an Ethernet cable from a device station and connecting it to another device station or a switching hub
• 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
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 129 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 = 204 + (106  Number of remote stations) + (Number of "RX setting" points  8) + (Number of "RWr
setting" points  2) [byte]
