Error Error name Error details and cause
code
1260H Multiple CPU • The execution interval of a
synchronization synchronous interrupt program
processing error has exceeded the set value.
• The multiple CPU synchronous
interrupt program (I45) did not
complete within the multiple CPU
fixed scan communication cycle.
1262H • The program execution section of
a synchronous interrupt program
has been exceeded.
• The multiple CPU synchronous
interrupt program (I45) did not
complete within the program
execution section.
1800H Annunciator ON • The annunciator (F) on status has
been detected.
1810H Operation • The PALERT(P) instruction was
continuation executed.
error
1811H Control CPU • An error has been detected in the
error CPU module.
1812H Module error • Tracking communications could
not be performed successfully due
to an error in the redundant
function module.
1830H Receive queue • The number of transient receive
full request exceeded the upper limit
of simultaneously processable
requests.
1831H Receive • Transient reception failed.
processing error
1832H Transient data • Too much transient transmission
error processing exists and transient
transmission cannot be
performed.
1845H Transient data • Too much transient transmission
buffer full processing exists and transient
transmission cannot be
performed.
1860H Network error • Tracking communications stopped
due to an error in the network or in
the redundant function module.
1861H Tracking • Tracking communications could
communication not be performed successfully due
error to an error in the network or in the
redundant function module.
Stop/ Action
continue
Continue • Check the detailed information (time
information) of the error by executing
module diagnostics using the
engineering tool, check the time
setting, and take the following actions:
(1) Check and correct the processing of
the interrupt program (I45) so that it
can be completed within the period
specified in the fixed scan interval
setting.
(2) Check and correct the fixed scan
interval setting value.
Continue • Check the detailed error information
(annunciator information) by executing
module diagnostics using the
engineering tool, and correct the
program corresponding to the
displayed annunciator number.
Continue • Check the detailed information (error
location information) of the error by
executing module diagnostics using
the engineering tool and check the
corresponding program - one that
outputs the program error code.
Continue • Check the error details by executing
module diagnostics using the
engineering tool and take an action.
Continue • The possible cause is malfunction due
to noise. Take measures to reduce
noise by checking the distance of wires
and cables, and the grounding status of
each device.
• Execute a module communication test.
If the same error code is displayed
again, the possible cause is a
hardware failure of the redundant
function module. Please consult your
local Mitsubishi representative.
Continue • Reduce the frequency of transient
transmission, and perform
transmissions again.
• Increase the frequency of transient
transmission by using the COM
instruction.
Continue • Reduce the frequency of transient
transmission, and perform
transmissions again.
Continue • Correct the number of transient
transmission executions.
Continue • Correct the number of transient
transmission executions.
Continue • Check the network status by executing
module diagnostics using the
engineering tool and take an action.
• If the error code is displayed again
even after taking an action, please
consult your local Mitsubishi
representative.
