36.4 List of Error Codes
Error details and cause
• Response data of the socket
communications instruction cannot be
created.
• The module mounting status of each
slot or the module model names differ
between the systems A and B.
• The module model names set in the
system parameters ("I/O Assignment
Setting") differ between the systems A
and B.
(The error is detected in the control
system or the standby system.)
• The CPU module model names differ
between the systems A and B.
• The link direct device setting of the
CPU parameters differs between the
systems A and B, or a CPU module
that does not support the extended
mode of the link direct device setting
is mounted.
(The error is detected in the control
system or the standby system.)
• The memory card mounting status
differs between the systems A and B.
(The error is detected in the control
system or the standby system.)
• The write protect switch status of the
memory card differs between the
systems A and B. (The error is
detected in the control system or the
standby system.)
• A file mismatch was detected in the
system consistency check. (The error
is detected in the standby system.)
Stop/ Action
continue
Stop/ • Increase the request interval.
continue • Decrease the number of request
nodes.
• Wait for a response to the
previous request before sending
the next request.
• Correct the timeout value.
Stop • Match the module mounting status
of each slot and the model of the
modules used between the
systems, and restart the CPU
module.
• Set the same module model name
in the system parameters ("I/O
Assignment Setting") for both
systems.
Stop • Mount the same CPU module, and
restart the CPU module.
• Match the link direct device setting
of the CPU parameters in both
systems, or replace the CPU
module with the one with a
firmware version supporting the
extended mode of the link direct
device setting. Then, restart the
system.
Stop • Match the memory card mounting
status between the systems, and
restart the CPU module.
Stop • Match the write protect switch
status between the systems, and
restart the CPU module.
Stop • Check the detailed information
(drive/file information) of the error
by executing module diagnostics
using the engineering tool, format
the corresponding drive of the
standby system CPU module,
write all files to the CPU module,
and restart the standby system
CPU module. (Set the same
number of steps as that of the
control system CPU module in
"Allocate Memory for Online
Program Change" on the
"Program Detail Setting" window.)
• Execute the memory copy to
match files in the control system
and the standby system. Then,
reset the CPU module of the
standby system and run it again. If
the same error code is displayed
again, the possible cause is a
hardware failure of the CPU
module. Please consult your local
Mitsubishi representative.
