Connecting/disconnecting a cable and turning OFF/ON a device
This section explains the following operations.
■
When a serial number (first five digits) of the master station is '17022' or higher
The actual network configuration and the network map of the CC-Link IE Field Network diagnostics may be a mismatch.
Whether mismatch is occurred or not can be checked using 'Network configuration mismatch occurrence status' (SB0098).
When using a ring topology, the following may be occurred.
• The station number of the loopback station cannot be detected correctly.
• Even if a switching hub is used, data link does not stop.
The actual network configuration and network configuration diagram can be matched by removing the
disconnected station of the CC-Link IE Field Network diagnostics. (

A data link error may momentarily occur in all the stations and output of the connected slave stations may turn
OFF since all stations on the network will be reconnected when removing the disconnected station. Set it to
maintain output data if needed. (

■
When a serial number (first five digits) of the master station is '17021' or lower
A data link error may momentarily occur in all the stations and outputs of the connected slave stations may turn OFF since all
stations on the network will be reconnected.
For a measure to above error, set the "Network Operation Setting" to maintain inputs from data link error station when outputs
need to be maintained at an occurrence of a data link error. (

Network Configuration Operations
Star topology • Turning OFF/ON a system on a slave station or the switching hub
• Connecting/disconnecting an Ethernet cable connected to the switching hub
• Disconnecting an Ethernet cable from a slave station and connecting it to another slave station or the switching hub
Line topology, ring topology • Simultaneously turning OFF/ON systems on multiple stations
• Simultaneously connecting/disconnecting Ethernet cables to/from multiple stations
(When a data link error station returns, a data link error will occur in all the stations.)
Insertion/removal
or turning OFF/ON
Instantaneous
error on all
stations.
