If the "Error(Illegal ring connection detected/Execute loopback)" icon is displayed
If the "Error(Illegal ring connection detected/Execute loopback)" icon is displayed in the network station, handle as below.
■
For system topologies without switching hubs
Ring connections when the "Basic Settings" "Network Topology" are set to "Line/Star", but this is a ring connection.
Handle as below.
■
For system topologies incorporating switching hubs
If the "Error(Illegal ring connection detected/Execute loopback)" icon is displayed for the following reasons.
• Ring connections when the "Basic Settings" "Network Topology" are set to "Line/Star", but this is ring connection.
Handle as below.
Corrective action
Remove an Ethernet cable from one of the stations on the network. (One of P1 or P2)
The network topology becomes line connection, and data link starts.
Corrective action
1.
Check whether "Network Topology" under "Basic Settings" is different from the configuration of the network. If it is
different, set "Ring connection" for "Network Topology" of "Basic Settings", and then write to the CPU module again.
When data link starts for the entire network, this solution is completed.
If data link does not start, perform Solution 2 and 3 below.
2.
If "Line/Star" is set for "Network Configuration Settings" under "Basic Settings", then handle as below.
• Remove one Ethernet cable connected to the switching hub and turn the switching hub power OFF to ON. (Repeat until
data link starts on the entire network. )
• When data link starts on the entire network, confirm the network configuration using CC-Link IE Field Network diagnosis.
This solution is completed. (
