Command Lists Section 5-1
ble only from specific nodes. For details, refer to 1-4-4 Write Protection
from FINS Commands Sent to CPU Units via Networks in the CS Series
PLC Operation Manual or the CJ Series PLC Operation Manual.
5-1-3 End Codes
The following table lists the main codes and the sub-codes, which combine to
form the end code (response code) returned for a FINS command. The prob-
able cause and corrections for each error code are also given.
Depending on the command, the destination code will sometimes make a
request of another node on a network. The other node is referred to as the
third node.
Note In addition to the end codes listed in the following table, the specific flags in
the end code word (bits 6, 7, and 15) may also be ON. If bit 15 is ON, an error
has occurred during a network relay operation. If bit 6 or 7 is ON, an error has
occurred in the destination CPU Unit. If this occurs, refer to the operation
manuals for the CPU Unit where the error occurred and remove the cause of
the error. The contents of the end code word are shown in the following dia-
gram.

01: Service
canceled
--- Service was canceled. Check the capacity of the destina-
tion area in the third node.
Data link status Service was canceled. Check the status of the data link.
01: Local node
error
01: Local node
not in network
Network status
of local node
Local node is not participat-
ing in the network.
Connect the node to the network.
02: Token
timeout
Maximum node
address
Token does not arrive. Set the local node to within the
maximum node address.
03: Retries
failed
--- Send was not possible during
the specified number of
retries.
Execute a communications test
between the nodes and re-examine
the system environment if it fails.
04: Too many
send frames
Number of
enabled send
frames
Cannot send because maxi-
mum number of event frames
exceeded.
Check event execution on the net-
work and reduce the number of
events per cycle.
Increase the maximum number of
event frames.
05: Node
address range
error
Node address Node address setting error
occurred.
Check the settings of the rotary
switches to be sure that the address
is within range and that each
address is set only once in the
same network.
06: Node
address
duplication
Node addresses The same node address has
been set twice in the same
network.
Change the address of one of the
nodes with the same address.
