Cause of error occurrence (details)
The number of data points were out of
range.
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 start device No. is out of range.
Or, 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
loop test 1.
All stations stopped communications
during loop test 1.
During RAM diagnostics, MFP send
buffer switching fails.
The value written to the object RAM
during RAM diagnostics and the readout
value are different.
Corrective action
Set the number of data points
to within 1 to 960 bytes.
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.
Correct the start device No.
Or, 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.
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.
