The following shows the error codes list.
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.

that does not support the function.
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.
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.
Bits corresponding to other than the head
station number were turned ON in the
Specification of remote device station to
be initialized (SW0014 to SW0017) to
instruct remote device station initialization
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.
Loop 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.

procedures are completed.
Turn on the remote device station
initialization procedure registration
instruction on the master station
(station No.0).

device station initialize procedure
registration function after setting the
remote device station initialize
procedure registration.
Turn ON only the bit corresponding to
the head station number in the
Specification of remote device station
to be initialized (SW0014 to
SW0017).
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 loop test while the link is
being established
Specify a station number that is no
greater than the highest
communication station number.
