Station Number Duplication Detection - Mitsubishi Electric CC-Link IE TSN User Manual

Station number duplication detection

If one network has CC-Link IE Field Network device stations with the same station number, a duplication error is detected.
After resolving the cause of error for the affected station, reset or turn off and on the module to restore the system.
If the network number is different, station number duplication is not detected.
Simultaneously turning off and on the power
When multiple device stations are simultaneously powered off and on or connected, an error is detected in the device stations
with duplicated station number and cyclic transmission and transient transmission cannot be performed. Data communication
can be done for all other stations.

Adding a device station to a network during data communication
If a device station is added to CC-Link IE Field Network during data communication, an error is detected in the added device
station and cyclic transmission and transient transmission cannot be performed. Data communication continues for all other
stations.

Even if one of the stations detected with a duplicate station number is disconnected, the other station does not
automatically return to the network.
