For an E71 where the loopback test failed, check the error and take corrective action. Then restart the E71-mounted station.
Restarting the E71 executes the initial process. To check whether the initial process has been completed in the E71, perform
the PING test. The PING test can be also performed on the "Loopback Test" window.
E71
Normal completion
The initial process for the target E71 has not
been completed normally.
There is an error, such as cable
disconnection and line disconnection, in the
line connection to the target E71.
The IP address of the target E71 is
incorrect. (The class or subnet address
differs from that of the E71.)
The same IP address has been set to
multiple target E71 modules.
The same network number or station
number has been set to multiple target E71
modules.
The Ethernet line is heavily loaded
(including a case where an error equivalent
to the error codes C030
occurring).
The routing parameter is not set (an error
equivalent to the error code C080
occurring).
The MELSOFT application transmission
port (UDP/IP) for the target E71 is locked
with the remote password.
The target E71 is a function version A
module.
The Ethernet line is heavily loaded
(including a case where an error equivalent
to the error codes C030
occurring).
Cause
Correct the following parameter settings.
• Basic setting
• Ethernet operation setting
• Initial setting
• Check the cable.
• Check the transceiver.
Correct the set values of the Ethernet
operation settings.
Perform the PING test on the "No response"
module. When the test is completed
normally, correct the set values in the basic
settings.
When the Ethernet line is not heavily
and C031 is
loaded, perform the test again.
H H
Correct the set value of the routing
is
H
parameter.
Disable the remote password setting and
write the parameter to the CPU module.
Check the module name and function
version.
When the Ethernet line is not heavily
and C031 is
loaded, perform the test again.
