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.
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.

1: Non-fatal CPU Unit error
Correction
---
Check the capacity of the destina-
tion area in the third node.
Check the status of the data link.
Connect the node to the network.
Set the local node to within the
maximum node address.
Execute a communications test
between the nodes and re-examine
the system environment if it fails.
Check event execution on the net-
work and reduce the number of
events per cycle.
Increase the maximum number of
event frames.
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.
Change the address of one of the
nodes with the same address.
