Error (hardware test)
Cause of error occurrence (details)
The transmission destination and source
stations were the same when other station
connection was specified.
An error occurred in the transient storage
buffer when a transient transmission of
greater than 1 k was being performed.
A non-existing access code/attribute was set.
An access code that does not exist was
used.
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.
A hardware error has been detected.
CHAPTER 15 TROUBLESHOOTING
Corrective action
Check the transmission destination
station number, or change to host
connection.
Wait a while and then retransmit.
Set a correct access code/attribute.
Use the correct access code.
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.
Please consult your local Mitsubishi
representative.
Set so that the number of processing
points does not exceed the device
range.
Please consult your local Mitsubishi
representative.
Specify the file register capacity.
Set to the intelli mode.
Please consult your local Mitsubishi
representative.
Check the mode specification.
Please consult your local Mitsubishi
representative.
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.
Please consult your local Mitsubishi
representative.
