4.5 List of Error Codes
Action
• Correct the transient data at the request source,
and retry the operation.
• If the error occurs again even after taking the above,
please consult your local Mitsubishi representative.
• Execute again after correcting the target station
number at the request source.
• If the request source is on another network, check if
the routing parameters are set correctly, and take
action.
• Correct the transient data at the request source,
and retry the operation.
• If the error occurs again even after taking the above,
please consult your local Mitsubishi representative.
• Check the network status using the CC-Link IE Field
Network diagnostics of the engineering 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 set correctly, and take
action.
• Execute again after correcting the CPU type of the
target station at the request source.
• If the request source is on another network, check if
the routing parameters are set correctly, and take
action.
• Execute again after correcting the arrival monitoring
time at the request source.
• When the own station, target station, or relay station
detected an error, identify the cause of the error and
take action.
• Lower the transient transmission usage frequency,
and then perform again.
• When "Communication Mode" in "Application
Settings" of the master station (submaster station) is
set to "High-Speed", change it to "Normal" and retry
the operation.
• Check if the switching hub and the cables at the
request source are connected properly.
• Execute again after correcting the number of
resends at the request source.
• When the own station, target station, or relay station
detected an error, identify the cause of the error and
take action.
• Lower the transient transmission usage frequency,
and then perform again.
• When "Communication Mode" in "Application
Settings" of the master station (submaster station) is
set to "High-Speed", change it to "Normal" and retry
the operation.
• Check if the switching hub and the cables at the
request source are connected properly.
• Execute again after correcting the network number
at the request source.
• If the request source is on another network, check if
the routing parameters are set correctly, and take
action.
• Set 1 to 2 for the target channel number in the
control data when executing the SEND instruction.
• Set 1 to 32 for the channel number when executing
the REMFR/REMTO/REMFRD/REMTOD
instruction.
• Execute again after correcting the number of the
channel used by own station in the control data.
