Item to check
The same socket service
is already in progress at
the specified socket num-
ber.
The specified socket is
not open.
Lack of available space in
internal buffers
Not opened due to sys-
tem settings.
Not opened due to a
change command from
the FINS/TCP connec-
tion’s remote node.
Closed by remote node;
opening again.
Opening again because
of a reception error.
Opening again because
of a send error.
Opening again because
of an RST response in
keep-alive.
Opening again because
there was no response in
keep-alive.
A connection is already
established with the
specified remote node.
The specified connection
number is not set as a
FINS/TCP client in the
Unit Setup.
While a remote node
change was being pro-
cessed for the specified
connection number, a
request for a change was
received and the pro-
cessing was stopped.
IP address conversion
failed.
IP address conversion is
set for automatic conver-
sion only.
Likely cause
Use the corresponding socket
status flag in PLC memory to
be sure that socket service
has finished before starting
services again.
Open the socket. (For TCP
sockets, wait until the connec-
tion is made.)
The load (traffic) on the Ether-
net Unit is too heavy. Check
your user applications.
Correctly set the Unit Setup,
FINS/TCP connection num-
ber, remote IP address, and
remote port number.
Correct the settings for the
FINS/TCP connection num-
ber, the remote IP address,
and the remote port number.
Correct the settings for the
Unit Setup, the FINS/TCP
connection number, the
remote IP address, and the
remote port number.
Correct the settings for the
FINS/TCP connection num-
ber, the remote IP address,
and the remote port number.
Check the IP address and
subnet mask in the Unit
Setup, and correct if neces-
sary.
Check the IP address conver-
sion setting in the Unit Setup.
This error will be generated
for the READ IP ADDRESS
TABLE command only.
