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.

Cause of error occurrence (details)
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 transmission station.
A line error has occurred.
A line error has occurred.
A line error has occurred.
In the remote device station initialize
procedure registration function, the
specification of the remote device station
initialize procedure registration was
turned off before all procedures were
completed.
The specification of the remote device
station initialize procedure registration
function was turned on at a station other
than the master station.
The specification of the remote device
station initialize procedure registration
function was turned on without setting the
remote device station initialize procedure
registration.
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
occupied stations).
However, this excludes the duplicate
head station number.
Corrective action
Check the line.
Check the line.
Check the line.
Check the line or check the
supply power and power supply
module of the transmission
station.
Check the line.
Check the line.
Check the line.
Do not turn the specification of the
remote device station initialize
procedure registration off until all
procedures are completed.
Turn on the specification of the
remote device station initialize
procedure registration at the
master station.
Turn on the specification of the
remote device station initialize
procedure registration function
after setting the remote device
station initialize procedure
registration.
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.
