Table 13.1 Error code list (5/6)
Cause of error occurrence (details)
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 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.
When a parameter registration request
2
(YnA) to E PROM was executed,
2
E PROM was out of order or exceeded
its write limit (10,000 times).
2
Data link start request by E PROM
parameter (YnB) was executed even
though the parameter was not registered
2
in E PROM.
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.
2
E PROM erasure request (YnD: ON) was
executed during data link (SB006E: ON).
The parameter registration request to
2
E PROM (YnA: ON) was executed in
excess of a maximum of 127 registration
times.
The parameter registration request to
2
E PROM (YnA: ON) was executed but
2
E PROM is faulty.
The corresponding station that is being
tested stopped communication during
line test 1.
All stations stopped communications
during line test 1.
13 - 10
Corrective action
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.
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.
Replace the module.
Register the parameter to
2
E PROM by a parameter entry
request (YnA).
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.
Execute a data link stop using
SW0002.
2
Execute the E PROM erasure
request (YnD: ON), switch
power off, or reset the CPU.
Change the module.
Check the cable and the
corresponding station.
Check the cables.
