Device Station Disconnection; Automatic Return - Mitsubishi Electric CC-Link IE TSN User Manual

Device station disconnection

The data link of the CC-Link IE Field Network device station where an error occurred is stopped, and the data link continues
only for stations that are operating normally.
In a line topology, the device station where an error occurred and all subsequent stations are disconnected.

Automatic return

The data link is automatically restarted when the CC-Link IE Field Network device station that was disconnected due to an
error becomes normal again.
Precautions
This table explains the precautions that appear when operating the system under one of the following conditions.
Condition
Star topology • Turning off or on a CC-Link IE Field Network device station
• The cable connected to the switching hub is unplugged and
unplugged, and the connection destination of CC-Link IE Field
Network device stations on the network is changed
Line topology Two or more CC-Link IE Field Network device stations
performed the following actions and returned to the network
successfully after a data link error
• Turning off or on the CC-Link IE Field Network device station
• Unplugging and plugging the cable connected to the module
of the CC-Link IE Field Network device station
Precautions
• The actual CC-Link IE Field Network configuration and the network map
of the "CC-Link IE TSN/CC-Link IE Field Diagnostics" window may not
match. The match status can be checked using 'Network configuration
mismatch occurrence status' (2009H.b8) of the remote buffer memory.
• The actual CC-Link IE Field Network configuration and the network map
of the "CC-Link IE TSN/CC-Link IE Field Diagnostics" window can be
matched by updating the network map from the "CC-Link IE TSN/CC-
Link IE Field Diagnostics" window.
• When updating the network map, data link is reestablished, so a data
link error may momentarily occur in all stations on CC-Link IE Field
Network and the output of connected CC-Link IE Field Network device
stations may be turned off.
