Codes of errors detected by other than the self-diagnostic function (6F00H to 6FFFH)
The following table lists the codes of errors, other than those detected by the self-diagnostic function of the CPU module.
Error Error name Error details and cause
code
6F00H Transient • The internal buffer area for transient processing is used to
execution error the maximum.
6F01H Transient • In transient transmission, timeout has occurred without
transmission transmission completion.
timeout error
6F02H Module error • An error has been detected in the redundant function
module.
6F23H
6F24H
6F25H Module • The operating status of the CPU module is in a state other
communication than STOP. (A test cannot be executed.)
test error
6F27H Module • A module communication test execution request was
communication received during the test.
test being • A module communication test termination request was
executed received during the test.
6F28H Module being • A module communication test execution request was
changed online received during online module change.
• A module communication test termination request was
received during online module change.
6F29H Module • A module communication test execution request was
communication received in the state where tracking cables are connected
test error incorrectly.
6F30H Transient Data communications cannot be performed with the other
execution error system because of any of the following reasons:
(redundant • The CPU module of the other system is powered off or in a
function module reset state.
communication • The tracking communication stops due to an error in the
being stopped) CPU module of the own or other system.
• Tracking cables are disconnected or incorrectly connected,
or failed.
• The redundant function module of the own or other system is
being changed online, a module communication test is being
performed for the module, or a hardware failure has
occurred in the module.
6F40H Transient The number of transient transmission requests exceeded the
execution error upper limit of simultaneously processable requests.
6F44H Transient frame • An invalid transient frame was received.
error
6F4AH
6F4BH
6F4CH
6F4DH
6F4EH
6F60H Module error • An error has been detected in the redundant function
module.
Action
• Temporarily stop transient transmissions, or reduce the
frequency. Then, perform transmissions again. Or, add the
COM instruction to the programmable controller CPU and
increase the frequency. If the same error occurs again, the
possible cause is a hardware failure of the redundant
function module. Please consult your local Mitsubishi
representative.
• Review the network status. If the same error occurs again,
the possible cause is a hardware failure of the redundant
function module. Please consult your local Mitsubishi
representative.
• Please consult your local Mitsubishi representative.
• Change the operating status of the CPU module to STOP,
and execute a module communication test.
• Since the module communication test is being executed,
execute the request again after the completion of the test.
• Since a module is being changed online, execute the
request again after the completion of the change.
• Connect one end of a tracking cable to the IN connector and
the other end to the OUT connector of the test target
redundant function module, and execute the request again.
• If a WDT error has occurred in the CPU module of the own
or other system, eliminate the error cause and then execute
the operation again.
• Check that there is no error or failure in the CPU module,
tracking cables, redundant function modules, and perform a
retry. Or, perform a retry after the online module change
processing or the module communication test ends. If the
same error code is displayed again, the possible cause is a
hardware failure of the CPU module, redundant function
module, base unit, or tracking cable. Please consult your
local Mitsubishi representative.
• Temporarily stop transient transmissions, or reduce the
frequency. Then, perform transmissions again.
• Check and correct the request data (send data) on the
request source side, and perform transmissions again.
• Please consult your local Mitsubishi representative.
