This bit turns ON if two nodes have the same node number. All communications
stop and the HER LED indicator flashes.
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.
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.
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.
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.
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.
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.
This section describes the error log that is used to record errors that have
occurred during FL-net Unit operation.
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.)
The following errors are recorded in the error log.
• Errors in network operation
• Errors in data transfers
• Error in the PLC
