36 ERROR CODES
36.4 List of Error Codes
1B78H Tracking
communication
error
• During tracking transfer, a tracking
communication error occurred. (The
error is detected in the control system
or the standby system. Note that if the
error is detected in the standby
system, the detailed information is not
stored.)
Continue • If the other system is powered off,
power on the system.
• If a WDT error has occurred in the
other system CPU module,
eliminate the error cause, and
restart the system.
• Connect tracking cables securely
and properly to the connectors of
the redundant function modules in
both systems.
• Set the program execution time of
the standby system shorter than
that of the control system. If the
shorter value cannot be set,
correct the SD1662 value.
• If the load on the communications
with the external devices via the
other system is high, perform the
communications without going
through the other system or
lighten the load on the
communications.
• Check the power supply status.
• Take measures to reduce noise. 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.

1B80H Tracking
transfer error
• The tracking data set in the CPU
parameters exceeds the allowable
tracking transfer range. (The error is
detected in the control system.)
Continue • Set the device/label data within
the allowable range in the CPU
parameters ("Tracking Device/
Label Setting").

instruction
execution
1B81H Tracking
transfer error
• The file register capacity has been set
in the CPU parameters of the control
system CPU module is less than the
file register capacity set for tracking
transfer. (The error is detected in the
control system.)
Continue • Check and correct the tracking
transfer settings in the CPU
parameters so that they will be
within the device range or the file
register capacity.
• Check and correct the device
settings or the file register capacity
setting in the CPU parameters.
At END
instruction
execution
1B82H • The file register data is transferred
from the control system CPU module
to the standby system CPU module
exceeding the capacity of the receive
side. (The error is detected in the
standby system.)
1BA0H Redundant
function module
error
• An error has been detected in the
redundant function module.
Continue • Check the detailed information
(system configuration information)
of the error by executing module
diagnostics using the engineering
tool, and check the status of the
redundant function module.
• Take measures to reduce noise. If
the same error code is displayed
again, the possible cause is a
hardware failure of the CPU
module, redundant function
module, or base unit. Please
consult your local Mitsubishi
representative.
