Table 13.1 Error code list (6/6)
Cause of error occurrence (details)
The attribute definition was invalid.
Alternatively, transient transmission was
performed even though the target station
does not support transient transmission.
The number of data was out of range.
The address was not a multiple of 16
when the bit device was accessed.
The specified combination (addresses
and points) exceeded the valid
processing range.
The file register capacity was not
specified.
A transient transmission was executed
when the target station was set to the I/O
mode.
The mode setting of the remote control
was incorrect.
A transient request was issued to a
station that has not secured a
communication buffer area.
The communication buffer size of the
corresponding station was out of range
when a dedicated instruction was
executed.
When the dedicated instruction is
executed, the transient data length is
greater than the communication buffer
size of the corresponding station.
The corresponding station that is being
tested stopped communication during
line test 1.
All stations stopped communications
during line test 1.
The station number setting switch setting
of the module is other than "0 to 64".
Alternatively, the last station number is
greater than 64.
Multiple master stations exist on the
same line.
Alternatively, line noise was detected at
power on.
A hardware error was detected.
There are too many transient requests to
the corresponding station.
The CPU monitoring timer timed out.

Corrective action
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.
Set the range to within 1 to 100
when writing, and 1 to 160
when reading.
Set the address to a multiple of
16 when accessing the bit
device.
Set so that the number of
processing points does not
exceed the device range .
Specify the file register
capacity.
Set to the intelli mode.
Check the mode specification.
Secure a communication buffer
area with a parameter.
Set the communication buffer
size of the corresponding
station within the range.
Make the communication buffer
size of the corresponding
station greater than the
transient data length.
Check the cable and the
corresponding station.
Check the cables.
Check the station number and
the number of occupied stations
of the module.
Reduce the number of master
stations on the same line to
one.
Alternatively, check the line
status.
There is most likely a hardware
error in either the QJ61BT11N,
the CPU module, the base unit
or other modules. Contact your
nearest Mitsubishi
representative.
Wait for a while before
transmitting again (transient
overload status).
Check the operation of the
target station.
