A
1B70H Tracking
communications
disabled
• Data communications with the
other system cannot be performed
even in backup mode. (The error
is detected in the control system
or the standby system.)
Continue • If the standby 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. (One cable shall be
connected between the IN connector of
the module in system A and the OUT
connector of the module in system B.
The other cable shall be connected
between the OUT connector of the
module in system A and the IN
connector of the module in system B.)
• 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.
 Always
1B71H Tracking
communication
error
• Data communications with the
other system cannot be performed
in one of the two tracking cables
even in backup mode. (The error
is detected in the control system
or the standby system.)
Continue • Connect tracking cables securely and
properly to the connectors of the
redundant function modules in both
systems.
• Take measures to reduce noise. If the
same error code is displayed again, the
possible cause is a hardware failure of
the redundant function module or
tracking cable. Please consult your
local Mitsubishi representative.
 Always
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.
• 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.
