• The head module received transient data addressed to a different network.
Check the network number and target station number, and retry the
operation.
• Check if the routing parameters are correctly set.
• Transient data transmission addressed to the own station was requested.
Check the network number and target station number, and retry the
operation.
• Check if the routing parameters are correctly set.
• Check if the switching hub and the cables at the request source are
connected properly.
• Connect the cable to the other port on the request source, and retry the
operation.
• Reduce the frequency of transient transmission, and retry the operation.
• A malfunction may have occurred due to noise. Check the wire and cable
distances and grounding condition of each device, and take measures to
reduce noise.
• Execute a unit test for the head module. If a failure occurs again, the
possible cause is a hardware failure of the head module. Please consult
your local Mitsubishi representative.
