Detectability Error code
(hexadecimal)
Error details Cause of error occurrence (details) Corrective action
Master station Local station
B803 Data points error
The number of data points were out of
range. Set the number of data points
to within 1 to 960 bytes.
B804
Attribute definition error
Transient transmission
unsupported station
specification error The attribute definition was invalid.
Alternatively, transient transmission was
performed even though the target station
does not support transient transmission.
Review the attribute definition.
Check the designation of the
target station number, as well
as the function version and
software version of the target
local station.
B805 Data points error The number of data was out of range.
Set the range to within 1 to 100
when writing, and 1 to 160
when reading.
B807 Device No. error
The start device No. is out of range.
Or, the address was not a multiple of 16
when the bit device was accessed.
Correct the start device No.
Or, set the address to a multiple
of 16 when accessing the bit
device.
B80D Setting range error
The specified combination (addresses
and points) exceeded the valid
processing range. Set so that the number of
processing points does not
exceed the device range .
B814
File register capacity setting
error The file register capacity was not
specified. Specify the file register
capacity.
B815 Module mode setting error
A transient transmission was executed
when the target station was set to the I/O
mode.
Set to the intelli mode.
B823 Remote control mode error
The mode setting of the remote control
was incorrect.
Check the mode specification.
B903 Transient request error
A transient request was issued to a
station that has not secured a
communication buffer area.
Secure a communication buffer
area with a parameter.
B904
Communication buffer size
setting error
The communication buffer size of the
corresponding station was out of range
when a dedicated instruction was
executed.
Set the communication buffer
size of the corresponding
station within the range.
B905 Transient data length error
When the dedicated instruction is
executed, the transient data length is
greater than the communication buffer
size of the corresponding station. Make the communication buffer
size of the corresponding
station greater than the
transient data length.
BA19 Corresponding station error
The corresponding station that is being
tested stopped communication during
loop test 1.
Check the cable and the
corresponding station.
BA1B All stations error
All stations stopped communications
during loop test 1.
Check the cables.
BA1E MFP send buffer switching error
During RAM diagnostics, MFP send
buffer switching fails.
Deal in the following procedure.
1) Check if the module is
mounted correctly.
2) Check if the module usage
environment is in the range
of the CPU module general
specification.
3) Check if the power supply
capacity is enough.
4) Check if the module operates
normally by itself. (Refer to
Section 6.2.)
5) Please consult your local
Mitsubishi representative.
BA1F RAM diagnostics error
The value written to the object RAM
during RAM diagnostics and the readout
value are different.
Deal in the following procedure.
1) Check if the module is
mounted correctly.
2) Check if the module usage
environment is in the range
of the CPU module general
specification.
3) Check if the power supply
capacity is enough.
4) Check if the module operates
normally by itself. (Refer to
Section 6.2.)
5) Please consult your local
Mitsubishi representative.
