Action
• Reduce the number of standby master stations on the
same line to one.
• Check the line status.
Please consult your local Mitsubishi representative.
Please consult your local Mitsubishi representative.
Please consult your local Mitsubishi representative.
Issue the request after the data link is started.
Please consult your local Mitsubishi representative.
Check the parameters or operation on the target station.
Check the target station.
Check the specified station number.
Execute the message transmission function on the master
station.
Set the transmission data size within the range.
Please consult your local Mitsubishi representative.
Please consult your local Mitsubishi representative.
Check the program to see if any prohibited remote output
(RY) has not been accessed. If the error occurs again even
after checking the above, the possible cause is a failure of
a master/local module or remote device station. Please
consult your local Mitsubishi representative.
• Check the operation of the target remote device station.
• Stop the data link then change the parameters.
• Check the program to see if any prohibited remote
output (RY) has not been accessed. If the error occurs
again even after checking the above, the possible cause
is a failure of a master/local module or remote device
station. Please consult your local Mitsubishi
representative.
• Set a larger value in 'Monitoring time setting' (SW0009) If
the error occurs again, check the modules and cables at
the destination.
• Stop data link after completion of message transmission.
• To execute message transmission while there is a stop
error in the CPU module, set "Data Link Setting at CPU
Failure" under "Supplementary Cyclic Settings" in
"Application Settings" to "Continue the Data Link".
• Set a larger value in 'Monitoring time setting' (SW0009) If
the error occurs again, check the modules and cables at
the destination.
• Stop data link after completion of message transmission.
• To execute message transmission while there is a stop
error in the CPU module, set "Data Link Setting at CPU
Failure" under "Supplementary Cyclic Settings" in
"Application Settings" to "Continue the Data Link".
Execute the message transmission function again. If the
error occurs again, the possible cause is a failure of a
master/local module or remote device station. Please
consult your local Mitsubishi representative.
