10-3 Error Log
This section describes the error log that is used to record errors that have
occurred during FL-net Unit operation.
10-3-1 Error Log
The error log records errors that have occurred during FL-net Unit operation.
Errors recorded in the log can be read by FINS command. (Refer to
ERROR
LOG READ on page 111.)
Logged Errors The following errors are recorded in the error log.
• Errors in network operation
• Errors in data transfers
• Error in the PLC

operation stopped)
Frame standby
FL-net version mismatch detected
Duplicate Common Memory
Common Memory data in effect notification
Common Memory setting complete
Bit Name Correction
8 Duplicate node number
detected This bit turns ON if two nodes have the same node number. All communications
stop and the HER LED indicator flashes.
9 Frame standby This bit turns ON if a receive frame cannot be detected. The power may not be ON
at the other node or there is a problem on the communications path. Check the
other node and the communications path.
10 FL-net version mismatch
detected This bit turns ON if you try to log on to an FL-net (Ver. 1.00) network. All communi-
cations stop and the HER LED indicator flashes. Make sure the network is config-
ured entirely of FL-net (Ver. 2.00) nodes. Once this flag turns ON, it will remain ON
until the power is turned OFF and back ON again or until the Unit is restarted.
12 Upper level operating sig-
nal error (PLC operation
stopped) A stop error or a persistent error has occurred in the CPU Unit. Use the CX-Pro-
grammer to clear the error on the CPU Unit.
The routing table settings are incorrect. Correct the routing tables using CX-Inte-
grator.
13 Common Memory data in
effect notification This bit turns ON if the Common Memory of the FL-net Unit receives data from all
the nodes and it starts to replace data in the CPU Unit.
14 Common Memory setting
complete This bit turns ON if the FL-net Unit can log on to the Data Link with no Common
Memory allocation setting error in the Unit at the time it logs on to the network.
If this flag is OFF when the local node logs on, the local node cannot access the
Data Link and only has access to the message service and token.
15 Duplicate Common Mem-
ory This bit turns ON if the same Common Memory is set for the local node that is
attempting to log on to the network and another node that is already logged on to
the network. In this case, the local node cannot access the Data Link and only has
access to the message service and token.
