C0EF
H
An error was detected in the programmable controller
CPU.
• Check that the programmable controller CPU and each
intelligent function module are properly connected.
• Check that the programmable controller CPU is not in the
reset status.
• Check if an error exists in the programmable controller
CPU. If an error exists, take the action required to correct
it.
• Replace the power supply module, programmable
controller CPU, or intelligent function module.
C0F0
H
An Ethernet module RAM error was detected in the
hardware test (H/W test).
• Perform the hardware test again. If an error occurs again,
the Ethernet module may have a hardware error. Please
consult your local Mitsubishi representative.
C0F1
H
An Ethernet module ROM error was detected in the
hardware test (H/W test).
• Perform the hardware test again. If an error occurs again,
the Ethernet module may have a hardware error. Please
consult your local Mitsubishi representative.
C0F3
H
A system error (major error) was detected in the CPU
module.
• Remove the error cause of the CPU module in the own
station.
C0F4
H
System error (The OS detected an error.)
• Follow the procedure below.
(1) Check if the Ethernet module, the power supply
module, and the CPU module are properly connected.
(2) Check if the operating environment of the Ethernet
module conforms to the general specifications of the
CPU module.
(3) Check if the power capacity is sufficient.
(4) Check if the hardware is normal according to the
manual for each module.
If the actions above do not solve the problem, please consult
your local Mitsubishi representative.
C0F5
H
System error (The OS detected an error.)
• Follow the procedure below.
(1) Check if the Ethernet module, the power supply
module, and the CPU module are properly connected.
(2) Check if the operating environment of the Ethernet
module conforms to the general specifications of the
CPU module.
(3) Check if the power capacity is sufficient.
(4) Check if the hardware is normal according to the
manual for each module.
If the actions above do not solve the problem, please consult
your local Mitsubishi representative.
C0F6
H
System error (The OS detected an error.)
• Follow the procedure below.
(1) Check if the Ethernet module, the power supply
module, and the CPU module are properly connected.
(2) Check if the operating environment of the Ethernet
module conforms to the general specifications of the
CPU module.
(3) Check if the power capacity is sufficient.
(4) Check if the hardware is normal according to the
manual for each module.
If the actions above do not solve the problem, please consult
your local Mitsubishi representative.
C0F7
H
An error has occurred in the self-loopback test.
• Because there may be congestion of packets on the line,
send data from the connected device after a certain period
of time.
• Check if the cable is disconnected.
If the actions above do not solve the problem, please consult
your local Mitsubishi representative.
