Probable cause
An error response was
returned for the com-
mand executed at the
remote node.
IP address of remote
node not set correctly in
IP address table or IP
router table.
Message packet was cor-
rupted by transmission
error.
Response monitor time
interval too short.
The transmission frame
may be corrupted or the
internal reception buffer
is full.
has been used.
A short frame (4 bytes) is
being used for the FINS
header frame.
Remote node address is
not set in the routing
tables.
Cannot determine desti-
nation because routing
tables have not been cre-
ated.
Routing table error
The maximum number of
network levels (3) was
exceeded in the com-
mand.
Section 10-4
Remedy
Check the command data and
status of the remote node.
Set IP address of remote
node into IP address table
and, if internetwork transmis-
sion is required, into the IP
router table.
Increase the number of trans-
mit retry attempts.
Increase the value for the
response monitor time param-
eter.
Check the error log and cor-
rect as required.
Check the command code.
Check the FINS header frame
length. The FL-net Unit does
not support short headers.
Set the destination address in
the routing tables.
Set routing tables at the local
node, remote node, and any
relay nodes.
Set the routing tables cor-
rectly.
Redesign the network or
reconsider the routing table to
reduce the number of relay
nodes in the command. Com-
munications are possible on
three network levels, including
the local network.
