Cause of error occurrence (details)
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 to 40 ".
H 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 other than 0 to 3 was set to the
station type in the station information
parameter.
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".
The operation when the CPU is down
specification parameter was set to a value
other than "0 or 1".
The scan mode parameter was set to a
value other than "0 or 1".
The number of automatic return stations
parameter was set to a value other than "1
to 10".
A duplicate station number was specified
with the station information parameter.
The station information parameter setting
does not meet the following condition:
C) < 2304
(16 A) + (54 B) + (88
A: Number of remote I/O stations
B: Number of remote device stations
C: Number of intelligent device stations
(including local stations)
The number of occupied stations in the
station information parameter was set to a
value other than "1 to 4".
The number of connected modules
parameter was set to a value other than "1
to 64".
Corrective action
Start logging with "RAM" checked.
For "RAM + FlashROM", replace
the module.
Set within the range of "1 to 40
H
Set a parameter value of 64 or less.
Set the occupied station number to
a value between "1 and 4".
Set a value within the setting range.
When the remote net ver.1 mode is
used, set a value within the range
from "0 to 3".
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.
Specify the standby master station
to a value within the range from "1
to 64".
Set a value within the range from "1
to 7".
Set "0 or 1".
Set "0 or 1".
Set a value within the range from "1
to 10".
