36.4 List of Error Codes
Error details and cause
• Even though an interrupt was
requested, there is no interrupt factor.
• An interrupt was requested from the
module with no interrupt pointer
setting.
• An execution interval error of the
synchronization interrupt program has
been detected.
• An inter-module synchronization error
has been detected.
• An inter-module synchronization error
has been detected.
• An error of the module set as the
inter-module synchronous master has
been detected.
• An execution interval error of the
synchronization interrupt program has
been detected.
• A multiple CPU synchronization error
has been detected.
• A multiple CPU synchronization error
has been detected.
• The specified I/O number is out of
range (other than 0 to FFH, 3E0 to
3E3H).
• The I/O number of the module that
does not exist was specified.
• The I/O number of the module that
does not support the instruction was
specified.
• The dedicated instruction specified in
the program cannot be executed in
the specified module or mode.
Stop/ Action
continue
Stop • Take measures to reduce noise.
• Reset the CPU module and run it
again. If the same error code is
displayed again, the possible
cause is a hardware failure of the
CPU module, base unit, or module
(I/O module or intelligent function
module) connected. Please
consult your local Mitsubishi
representative.
Stop • Check and correct the interrupt
pointer setting in the module
parameters.
• Take measures so that no
interrupt is requested from the
module with no interrupt pointer
setting.
• Check and correct the interrupt
setting in the buffer memory of the
intelligent function module.
• Correct the BASIC program
executed in the QD51.
Stop/ • Check the module set as the inter-
continue module synchronous master.
• Correct the inter-module
synchronous master settings.
• Take measures to reduce noise.
• Reset the CPU module and run it
Stop
again. If the same error code is
displayed again, the possible
cause is a hardware failure of the
CPU module, base unit, extension
cable, or module (I/O module or
intelligent function module)
connected. Please consult your
local Mitsubishi representative.
Stop/ • Take measures to reduce noise.
continue • Reset the CPU module and run it
again. If the same error code is
displayed again, the possible
cause is a hardware failure of the
CPU module or base unit. Please
Stop
consult your local Mitsubishi
representative.
