Description
A communication error occurred with direct
connection.
There is an error in the setting value for the
port number of the MELIPC.
The port number setting of the external
device is incorrect.
• In TCP/IP, an own station port number
that is the same as SLMP is specified.
• In TCP/IP, for the same communications
device, the same connection for own
station port number and communication
other device port number is already used.
• In UDP/IP, an own station port number
that is the same as SLMP is specified.
• In UDP/IP, the specified own station port
number is being duplicated in use.
Error in the other device IP address settings
values at open processing.
A connection could not be established in
TCP connection open processing.
The data length exceeds the permissible
range.
Failed to communicate due to a
retransmission timeout.
• The presence of the external device
cannot be checked.
• The TCP connection from the external
device was cut.
• Communication was rejected by a check
of the full passive side, and the TCP
connection was cut.
Sending processing cannot be performed
because the cable is not connected or cut.
Corrective action
• If it is not a direct connection, do not
specify a direct connection.
• In the case of a direct connection, do not
switch OFF or reset the MELIPC or
remove a cable during communication.
Correct the port number.
Correct the port number.
• Specify a port number that does not
duplicate a port number used with SLMP.
• Review MELIPC and other device port
numbers, and correct in order that there
is no duplication.
• Specify a port number that does not
duplicate a port number used with SLMP.
• Review MELIPC and other device port
numbers, and correct in order that there
is no duplication.
Correct the IP address. Class is A/B/C.
• Check the operation of the target device.
• Check other device open processing.
• Review the MELIPC port number, other
device IP address/port number, and
opening method.
• Check that connection cables have not
been removed.
• Correct the data length.
• If the sent data quantity exceeds the
specified quantity, this will be split and
then sent.
• Review the IP address and Ethernet
address of the external device, and then
correct if necessary.
• Check whether the external device has
an ARP function, and then communicate
with an external device with an ARP
function.
• Check the operation of the target device.
• Because there may be congestion of
packets on the line, send data after an
arbitrary time.
• Check the status of the line, including the
cables, hubs, routers, and other external
devices.
• Check whether the initial processing and
open processing of the external device is
completing normally.
• Check whether the communication data
code settings of the external device is
binary code.
• Check the operation of the target device.
• Check whether connection cables have
been removed.
• Check whether the external device IP
address settings of the full passive side
match the IP address of the active side.
• Check whether connection cables have
been removed.
• Perform a ping test from the external
device and check for problems on the
line.
• Perform a self-diagnosis test and check
for problems with the MELIPC.
