Cause of error occurrence (details)
Any of the following were attempted to be
executed to the same station. (Including
the same requests)
• Message transmission function
• Remote device station initialization
procedure registration function
• G(P).RISEND or G(P).RIRCV
instruction
• Remote device station access from a
peripheral.
The station number setting of the module
is other than "0 to 64".
Alternatively, the last station number is
greater than 64.
Multiple master stations exist on the
same line.
Alternatively, line noise was detected at
power on.
Multiple standby master stations exist on
the same line.
A data link error occurred on all stations
during a message transmission.
The target station specified for the
message transmission function is in any
of the following status.
• No network parameter is set.
• The specified station No. is not the
head station number.
• The station is set as a reserved station.
• A data link error (including All stations
data link error) has occurred.
The message transmission was
performed for any other than remote
device stations.
The station No. specified for the
message transmission function is outside
of the range between "1 and 64".
Execution of the message transmission
function was attempted from other than
the master station.
In the message transmission function,
the send data size is outside the range.
With the message transmission function,
abnormal data were received.
Corrective action
Execute a request after
completion of another
processing.
Check the station number and
the number of occupied stations
of the module.
Reduce the number of master
stations on the same line to
one.
Alternatively, if data link starts
when turning on the SB0007
(Master station duplication error
canceling request), check the
line status.
Reduce the number of standby
master stations on the same
line to one.
Alternatively, check the line
status.
After the data link status is
recovered, perform the
message transmission again.
Check network parameters or
remote device stations'
operations.
Check the target station.
Check the specified station No.
Execute the message
transmission function on the
master station.
Change the send data size so
that it will be within the range.
Check the program to see if any
prohibited remote output (RY)
has not been accessed.
If the same error persists after
checking the above, the master
module or remote device
station may be faulty. Please
consult your local Mitsubishi
representative.
