The FL-net Unit will output error status to the following word in the PLC Data
Area Interface of the CPU Unit. This information can be used in troubleshoot-
ing errors.
1,500 + (25 × unit number) + 6

The corresponding bit will turn ON when an error occurs
This bit turns ON if there is a Common Memory allocation error in the local node
setting range of the FA Link (Data Link) settings. Use the CX-FLnet or FL-net Unit
Support Software to re-set the FA Link (Common Memory) allocation settings
This bit turns ON if there is a PLC Area allocation error in the local node setting
range or another node setting range of the FA Link (Data Link) settings. Use the
CX-FLnet or FL-net Unit Support Software to re-set the FA Link (Common Memory)
allocation settings.
This bit turns ON if a token monitoring timeout occurs while the local node is hold-
ing the token. Processing may be delayed because of system traffic, so recheck the
system configuration or extend the token monitoring timeout setting with the CX-
FLnet or FL-net Unit Support Software.
The following cannot be used as IP address settings.
• Host IDs that are all 0 or all 1.
• Network IDs that are all 0 or all 1.
• Subnetwork IDs that are all 1.
• Addresses beginning with 127 (7F Hex).
Reset the IP address.
The communications cable may be disconnected. Make sure the cable is mounted
securely.
Restart the PLC. If the problem persists, replace the FL-net Unit.
