Check point
Socket status The same socket service is
area already in progress at the
specified socket number.
Socket status The specified socket is not
area open.
System load The internal buffers are full
because there is too much traf-
fic at the local node, preventing
data from being sent.
Unit settings The socket is not open for Sys-
tem Settings.
The socket is not open
because of the remote node
conversion command for the
FINS/TCP connection.
The socket is reopening
because the connection to the
remote node has closed.
The socket is reopening
because of a reception error.
The socket is reopening
because of a transmission
error.
The socket is reopening
because RST received in
response to keep-alive.
The socket is reopening
because of no keep-alive
response.
Command data A connection is already estab-
lished with the specified
remote node.
Unit settings and The specified connection num-
command data ber is not set as a FINS/TCP
client in the Unit Setup.
Command data While a remote node change
was being processed for the
specified connection number, a
request for a change was
received and the processing
was stopped.
High-speed The high-speed option for the
option for socket socket service was enabled in
service in Unit the Unit settings, and the

Probable cause
Use the socket status flag in PC
memory to be sure that socket
service has finished before start-
ing services again.
Open the socket. For TCP sock-
ets, be sure to wait until connec-
tion is made.
Correct the user application to
reduce traffic at the Ethernet
Unit.
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 number, 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 number, the
remote IP address, and the
remote port number.
Disable the high-speed option or,
if it remains enabled, use the
socket service by manipulating
specific bits.
Check the IP address and subnet
mask in the System Setup and
be sure that settings are correct.
Check the mode settings in the
System Setup. This error will be
generated for the READ IP
ADDRESS TABLE command
only.
