Check that the command can be requested to all or a group of stations at the
request source, and retry the operation.
Correct the header information at the request source, and retry the
operation.
Set the station number in the parameter setting, and retry the operation.
• Check if the switching hub and the cables at the request source are
connected properly.
• Connect the cable to the other port on the module, and retry the operation.
• Reduce the frequency of transient transmission, and retry the operation.
• Correct the request command at the request source, and retry the
operation.
• Check the serial number (first five digits) of the master/local module. If the
master/local module does not support the function, replace it with the
master/local module with the latest version.
Correct the data length at the request source, and retry the operation.
Correct the request command at the request source, and retry the operation.
Correct the number of read/write device data at the request source, and retry
the operation.
Correct the attribute code at the request source, and retry the operation.
Correct the access code at the request source, 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.
• A cable test cannot be executed for a different network. Correct "Testing
Station Setting", and execute the cable test again.
• Transient data that cannot be sent to a different network were received.
Correct the network number or the target station number at the request
source, and retry the operation.
• A communication test cannot be executed on a relay sending station.
Correct "Target Station" setting, and execute the communication test
again.
• Transient data of the application type that cannot be executed on the own
station were received. Correct the application type or the target station
number at the request source, and retry the operation.
The SEND instruction cannot be executed on the head module.
Modify the program of the master and local stations so that the SEND
instruction may not be executed.
Correct the request command at the request source, and retry the operation.
• Check the network status by executing the CC-Link IE Field Network
diagnostics using the programming tool, and take action.
• Check if the switching hub and the cables at the request source are
connected properly.
• If the request source is on another network, check if the routing
parameters are correctly set.
Correct the request command at the request source, and retry the operation.
