36.4 List of Error Codes
Error details and cause
• The internal buffer area for transient processing
is used to the maximum.
• In transient transmission, timeout has occurred
without transmission completion.
• An error has been detected in the redundant
function module.
• The operating status of the CPU module is in a
state other than STOP. (A test cannot be
executed.)
• A module communication test execution request
was received during the test.
• A module communication test termination
request was received during the test.
• A module communication test execution request
was received during online module change.
• A module communication test termination
request was received during online module
change.
• A module communication test execution request
was received in the state where tracking cables
are connected incorrectly.
Data communications cannot be performed with the
other system because of any of the following
reasons:
• The CPU module of the other system is powered
off or in a reset state.
• The tracking communication stops due to an
error in the 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.
The number of transient transmission requests
exceeded the upper limit of simultaneously
processable requests.
• An invalid transient frame was received.
• 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 CPU module and increase the
frequency of transient processing. 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.
