Table 13.1 lists the error codes that are stored in the link special registers (SW).
When the standby master station is operating as the master station, the detectability is
identical to that of the master station.
When the standby master is operating as a local station, the detectability is identical to
that of the local station.
Table 13.1 Error code list (1/6)
Cause of error occurrence (details)
———
Data link restart (SB0000) was executed
for the station that was performing a data
link.
Data link stop (SB0002) was executed
for the station that had stopped a data
link.
A line error has occurred.
A line error has occurred.
A line error has occurred.
A line error has occurred or an
instantaneous power failure has occurred
at the send station.
A line error has occurred.
A line error has occurred.
A data link error occurred at the
corresponding station during transient
transmission.
A transient request was issued to other
than the intelligent device station.
Line test request was issued while the
link was stopped.
The specified station number exceeded
the highest communication station
number during temporary error invalid
request/temporary error invalid cancel
request.
The station number was not specified during
temporary error invalid request/temporary
error invalid cancel request.
An error was detected in a remote
station, intelligent device station or
standby master station when a line test
was performed.
A station number other than the head
station number was specified during
temporary error invalid request/temporary
error invalid cancel request.
All stations were in data link error status
when one of the following requests was
made:
• SB0000 (data link restart)
• SB0002 (data link stop)
The station number of the slave station is
outside of the range between "1 and 64".
The station number of the connected
module was duplicated (including
number of occupied stations).
However, this excludes the duplicate
head station number.
Corrective action
Handle by referring to the
troubleshooting section of the Serial
Communication Module User's
manual.
Execute Data link restart (SB0000)
for the station that has stopped a
data link with Data link stop
(SB0002).
Execute Data link stop (SB0002) for
the station that is performing a data
link.
Check the line.
Check the line.
Check the line.
Check the line, or check the supply
power and power supply module of
the send station.
Check the line.
Check the line.
Check the communication status of
other stations, whether or not a
temporary error invalid station is
specified, or if the corresponding
station is stopped.
Check the target station.
Perform a line test while the link is
being established.
Specify a station number that is no
greater than the highest
communication station number.
Set a specified station number.
(SW0003, SW0004 to SW0007)
Check that the remote station,
intelligent device station or standby
master station is operational and
that the cable is not disconnected.
Specify a head station when
temporary error invalid
request/temporary error invalid
cancel request is requested.
Request again after the data link
becomes normal.
Set the station number of the slave
station within the range between "1
and 64".
Check the module station number.
