Error
When "MELSEC-A (Ethernet Module)/MELSEC-
FX3 (Ethernet Block/Adapter)" was specified in
"Destination" of the simple PLC communication
function, the function was executed while CPU
exchange timing setting (SW7) of the Ethernet
module is off and the CPU module on the
destination is in the RUN status.
• Turn on CPU exchange timing setting (SW7) of
the destination.
• Set the CPU module on the destination to STOP
and execute the function again.

Ethernet I/F
Error
When "MELSEC-A (Ethernet Module)/MELSEC-
FX3 (Ethernet Block/Adapter)" was specified in
"Destination" of the simple PLC communication
function, communications between the CPU
module and the Ethernet module failed. (After
the Ethernet module normally receives a request
from another node, communications between the
CPU module and the Ethernet module ailed due
to a noise or other causes.)
• Ensure that the operating environment for the
system meets the general specifications of the
CPU module.
• Reset the CPU module.
• Execute again. If the same error code is
displayed, the cause is a hardware failure of the
CPU module. Please consult your local
Mitsubishi representative.

Ethernet I/F
Error
When "MELSEC-A (Ethernet Module)/MELSEC-
FX3 (Ethernet Block/Adapter)" is specified in
"Destination" of the simple PLC communication
function, an incorrect device is specified.
• Check the specified device name.
• Check the specified device No.
• Check the device assignment parameters of the
CPU module (destination).

Ethernet I/F
Error
When "MELSEC-A (Ethernet Module)/MELSEC-
FX3 (Ethernet Block/Adapter)" was specified in
"Destination" of the simple PLC communication
function, a system error occurred. (The possible
cause is malfunction due to noise or other
causes or hardware failure).
• Check that the power supply module and the
CPU module are mounted/connected properly.
• Ensure that the operating environment for the
system meets the general specifications of the
CPU module.
• Check whether the power capacity is sufficient.
• Reset the CPU module.
• Execute again. If the same error code is
displayed, the cause is a hardware failure of the
CPU module. Please consult your local
Mitsubishi representative.
