(g) Connection of an external power supply
The external power can be directly supplied to the CC-Link IE Controller Network module with external power
supply function. ( Page 134, Section 4.4.7)
Even if a CPU module power goes down in a network, data link will be continued among normally operating
stations without being disrupted at the power-down station. (Loopback does not occur.)
Data link is also continued between failed stations when power failure has occurred on CPU modules on
multiple stations.
