Error
• Write the network parameters to the CPU module again.
• If this error persists, please consult your local Mitsubishi representative.
• Write the network parameters to the CPU module again.
• If this error persists, please consult your local Mitsubishi representative.
• A malfunction may have occurred due to noise. Check the wire and cable
distances and grounding condition of each device, and take measures
against noise.
• Execute hardware and self-loopback tests. If a failure occurs again, the
hardware of the master/local module may be faulty. Please consult your
local Mitsubishi representative.
• A malfunction may have occurred due to noise. Check the wire and cable
distances and grounding condition of each device, and take measures
against noise.
• Execute hardware and self-loopback tests. If a failure occurs again, the
hardware of the master/local module may be faulty. Please consult your
local Mitsubishi representative.
• Replace the CPU module.
• If this error persists, please consult your local Mitsubishi representative.
Check the error in the "PLC Diagnostics" window of the programming tool.
The power is off. Turn it on.
Correct the total number of slave stations in the buffer memory start
parameter area.
Correct the station number range in the buffer memory start parameter area.
Correct the total number of slave stations in the buffer memory start
parameter area.
Correct the slave station setting information in the buffer memory start
parameter area.
Correct the station type in the buffer memory start parameter area.
Correct the offset values or points assigned to the devices of each station in
the buffer memory start parameter area.
Correct the setting flag in the buffer memory start parameter area.
Correct the setting flag, application parameter, and information setting data
for each station in the buffer memory start parameter area.
• The maximum number of writes to the flash ROM is exceeded.
• Reset the CPU module. If a failure occurs again, the hardware of the
master/local module may be faulty. Please consult your local Mitsubishi
representative.
• A malfunction may have occurred due to noise. Check the wire and cable
distances and grounding condition of each device, and take measures
against noise.
• Execute hardware and self-loopback tests. If a failure occurs again, the
hardware of the master/local module may be faulty. Please consult your
local Mitsubishi representative.
Correct the setting flag in the buffer memory start parameter area.
