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

Master station duplication detection

If one network has multiple CC-Link IE Field Network master stations, an overlap 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.
Simultaneously turning off and on the power
When multiple master stations are simultaneously powered off and on or connected, an error is detected in all master stations
and cyclic transmission and transient transmission cannot be performed in all stations.

• CC-Link IE Field No.0: CC-Link IE Field Network master station (No.0)
• CC-Link IE Field No.1: CC-Link IE Field Network device station (No.1)
• CC-Link IE Field No.2: CC-Link IE Field Network device station (No.2)
Adding another master station to a network during data communication
If another master station is added to CC-Link IE Field Network during data communication, an error is detected in the added
master station and cyclic transmission and transient transmission cannot be performed in all stations. Data communication
continues for all other stations.
