Cause of error occurrence (details)
During data link, the logs were cleared with
"RAM + FlashROM" checked.
Clear of the logs was attempted with "RAM +
FlashROM" checked, but logging started
even though the clear was incomplete.
The logs were attempted to be stored in the
flash ROM even though the logs could not be
stored in flash ROM.
The total number of storing the logs in the
flash ROM exceeded 100,000 times.
The station number (including the number of
occupied stations) of the station information
parameters was set to "other than 1
40
".
H
The total number of occupied stations set
with the station information parameter
exceeded 64.
The number of all occupied stations in the
station information parameter was set to "0".
The delay time setting in the master station
network parameters is out of the setting
range.
When the remote net ver.1 mode is used, a
value set to the station type in the station
information parameter is out of the setting
range.
The number of remote device stations was
set to "43 stations or more" with the station
information parameter.
The number of intelligent device stations
(including local stations) was set to "27
stations or more" with the station information
parameter.
"Other than module head station number" or
"station number not specified in the
parameter" was set with the invalid station
specification parameter.
<Example of other than head station
number>
A bit other than that for station number 5 was
ON for a module occupies 4 stations (station
numbers 5 to 8).
The total size of the communication buffers
in the station information parameter
exceeded 4 K words.
The total size of the automatic update buffer
in the station information parameter
exceeded 4 K words.
The standby master station parameter was
set to a value other than "1 to 64".
The retry count parameter was set to a value
other than "1 to 7".
CHAPTER 15 TROUBLESHOOTING
Corrective action
Please consult your local Mitsubishi
representative.
Stop the data link and then clear the
logs.
Clear the logs again with "RAM +
FlashROM" checked.
After clearing the logs with "RAM +
FlashROM" checked, start logging.
Or, start the logging with "RAM"
checked.
Start logging with "RAM" checked.
For "RAM + FlashROM", replace the
module.
Set within the range of "1
H
to
H
Set a parameter value of 64 or less.

value between "1 and 4".
Set 0 in the delay time setting.
When the remote net ver.1 mode is
used, set a value within the range
from 0 to 2.
Please consult your local Mitsubishi
representative.
Set the remote device station to "42
stations or less" with the station
information parameter.
Set the intelligent device station to
"26 stations or less" with the station
information parameter.
Set the "Head station number of the
module".
Do not specify any of the stations not
specified with the parameter.
Set the total size of the
communication buffers to 4 K words
or less.
Set the total size of the automatic
update buffer to 4 K words or less.
