• Check the network status using the CC-Link IE Field Network diagnostics
of the programming tool.
• If the number of slave stations per network is more than the number of
connectable stations, reduce it to the number of connectable stations or
less.
• 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.
• The hardware of the Simple Motion module may be faulty. Please consult
your local Mitsubishi service center or representative.
• If the own station, or target station is disconnected from the network,
identify the cause of the disconnection and take action.
• When the target station is overloaded and cannot receive transient data,
reduce the frequency of transient transmission and retry the operation.
• Check if the cables and the switching hub are connected properly.
• Reduce the frequency of transient transmission, and retry the operation.
• The hardware of the Simple Motion module may be faulty. Please consult
your local Mitsubishi service center or representative.
• Reduce the frequency of transient transmission, and retry the operation.
• Check if the switching hub and the cables at the request source are
connected properly.
• If the own station, or target station is disconnected from the network,
identify the cause of the disconnection and take action.
• Correct the number of the station for which transient data is to be sent,
and retry the operation.
• Check if the cables and the switching hub are connected properly.
• Reduce the frequency of transient transmission, and retry the operation.
