*1 The error details written here are for the case when Error history is A06H to A09H (for Error history 1 (address: A00H to
A0FH)). The following information of when an error has occurred are stored in this area.
• Error occurrence address
• Process value (PV)
• Manipulated value (MV)
• Set value (SV)
For details on Error history, refer to the following.

Page 363, Appendix 3 (69)
When multiple errors have occurred, only the latest error code is stored in Latest error code (RWr0) or Latest warning code
(RWr2).
The errors that occurred in the past can be checked with the error history of the engineering tool.
For the error history, refer to the following.
• Checking with the command execution of slave station (

*1
Action
0160H Minor error
Remote buffer
memory access
error
A buffer memory
area other than the
remote buffer
memory areas has
been accessed using
the REMFR/REMTO
instruction.
0 is stored in Error occurrence
address, Process value (PV),
Manipulated value (MV), and
Set value (SV).
Correct the setting data of the
REMFR/REMTO instruction to access the
remote buffer memory.
0930H Moderate error
Cyclic data update
watch time setting
outside the range
The value set in
Cyclic data update
watch time (address:
7H) is outside the
range of 0 to 20. • 0007H is stored in Error
occurrence address.
• 0 is stored in Process value
(PV), Manipulated value
(MV), and Set value (SV).
Set a value within the range of 0 to 20 in
Cyclic data update watch time (address:
7H).
0940H Minor error
Station number
switch changed
error
The station number
setting switch has
been changed while
the module power is
on.
0 is stored in Error occurrence
address, Process value (PV),
Manipulated value (MV), and
Set value (SV).
Set the switch again to the same station
number that was set while the module
power was on.
0950H Moderate error
Clock data outside
the range
The clock data
acquired from the
CPU module is
invalid. 0 is stored in Error occurrence
address, Process value (PV),
Manipulated value (MV), and
Set value (SV).
The possible cause is an affect of noise or
a hardware failure. If the same error has
occurred even after measures have been
taken against noise, please consult your
local Mitsubishi representative.
0960H Major error
Network No.
changed through
the network Invalid change of a
network number has
been detected.
0 is stored in Error occurrence
address, Process value (PV),
Manipulated value (MV), and
Set value (SV).
The possible cause is an affect of noise or
a hardware failure. If the same error has
occurred even after measures have been
taken against noise, please consult your
local Mitsubishi representative.
0970H Major error
Station No.
changed through
the network Invalid change of a
station number has
been detected.
0 is stored in Error occurrence
address, Process value (PV),
Manipulated value (MV), and
Set value (SV).
The possible cause is an affect of noise or
a hardware failure. If the same error has
occurred even after measures have been
taken against noise, please consult your
local Mitsubishi representative.
D529H Major error
Communication
error 1
A communication
error has occurred.
0 is stored in Error occurrence
address, Process value (PV),
Manipulated value (MV), and
Set value (SV).
• The possible cause is malfunction due to
noise. Check the cable distance or
grounding condition of each device and
take measures against noise.
• Execute a unit test for the module. If the
same error has occurred, the possible
cause is a hardware failure of the
module. Please consult your local
Mitsubishi representative.
