Appendix 2
When an error is detected by the self-diagnosis function, the error code is stored to a special register (SD). Additionally, if an
error occurs during a communication request from either MI Configurator or the network system to this product, the error code
is returned to the request source.
This section shows the details of errors that occur in this product and their corrective actions.
Check of error codes
An error code can be checked with the following methods
If multiple errors have occurred at the same time, then these will be handled from the oldest first according to
their history date.
Checking error codes with MI Configurator
Codes of errors that are occurring on the MELIPC can be checked using the MELIPC diagnosis of MI Configurator.
[Diagnostics]  [MELIPC Diagnostics]
Checking by the dot matrix LED
Codes of errors that occurred can be checked using [Error code] of menu selection mode.
(MELIPC MI5000 Series User's Manual (Startup))
Checking by a user program
Error codes can be acquired by C Controller module dedicated functions. In addition, the acquired error codes can be
checked by the user program outputting them to the dot matrix LED or monitor. (MELIPC MI5000 Series Programming
Manual (VxWorks))
Error code system
Error codes are represented in four-digit hexadecimal number (unsigned 16-bit integer).
Errors that can be detected by the self-diagnosis function and common errors that can be detected during data
communications between modules are included in the following table.
