Detectability Error code
(hexadecimal)
Error details Cause of error occurrence (details) Corrective action
Master station Local station
During execution of message
transmission, a data link error occurred
on the station.
Check the operation of the
target remote device station.
During execution of message
transmission, some parameters were
changed.
Stop the data link, and then
change parameters.
BC51
Message transmission
handshake failure
With the message transmission function,
abnormal data were received.
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.
In the message transmission function, a
communication timeout has occurred.
Increase the value for
Monitoring time setting
(SW0009).
If the error occurs again, check
the target module and cables.
BC52
Message transmission
handshake timeout
Data link stop (SB0002) was executed
during the message transmission. Stop data link after completion
of message transmission.
In the message transmission function, a
communication timeout has occurred.
Increase the value for
Monitoring time setting
(SW0009).

BC54
BC55
Message transmission
handshake failure With the message transmission function,
abnormal data were received.
Execute the message
transmission function again.
If the same error persists, the
master module or remote
device station may be faulty.
Please consult your local
Mitsubishi representative.
BC57 Requests overlapped error
Executions of multiple requests for
message transmission or remote device
station access from a peripheral were
attempted to the same station.
Execute a request after
completion of another
processing.
BC58
BC59
Message transmission
handshake failure With the message transmission function,
abnormal data were received.
Execute the message
transmission function again.
If the same error persists, the
master module or remote
device station may be faulty.
Please consult your local

BC5D
BC5E
BC5F
Message transmission
handshake failure With the message transmission function,
abnormal data were received.
Execute the message
transmission function again.
If the same error persists, the
master module or remote
device station may be faulty.
Please consult your local
Mitsubishi representative.
BC60
Invalid number of
simultaneously executed
message transmissions The message transmission function was
executed simultaneously for 5 or more
remote device stations.
Simultaneously execute the
function for 4 stations or less.
BC70
No. of concurrent execution
error
(Remote device station access) Too many remote device station
accesses were requested from
peripherals.
Execute four requests or less at
the same time.
BC71
