Fatal Error Reporting
If the ECM850 encounters a Fatal error, it tries to save diagnostic information to non-volatile
storage. The RX3i CPU then resets the ECM850.
Diagnostic information can be viewed from the Command Line Interface using the show
debug fataIInfo command.it, refer to "Status Reporting".
5.5
ECM850's Local Log Table
The ECM850's local log table contains entries indicating events and errors. There can be
three types of entries in the local log table:
•
•
•
The ECM850 maintains the entries in its local log table until they are cleared from the
Command Line Interface. Entries in the local log are preserved across power-cycles.
The Local Log table can only be cleared from the Command Line Interface using the clear
log command. Clearing the RX3i CPU fault tables or restarting the ECM850 does NOT clear
the local log table.
If the ECM850's Local Log table overflows, new entries overwrite the oldest entries, which
are lost. If that happens, the Command Line Interface indicates the number of entries that
have been discarded. The count of discarded entries is reset to zero when the local log table
is cleared.
The ECM850's STATUS LED provides an indication that a new fault has been added to the
module's local log since either the last time the module was restarted, or since the last time
the log was cleared. The STATUS LED is ON at powerup, after the Local Log has been cleared,
or after executing the clear statLED command from the Command Line Interface. When a
fault occurs the STATUS, LED turns OFF to indicate that a new fault has been logged.
5.5.1
Local Log Table-Only Faults
The following faults appear only in the local log table of the ECM850. They have an Entry
Type of Local Fault, when viewed using the Command Line Interface log details command.
The Local Log Table also contains the faults that are reported to the RX3i CPU. Those faults,
which are listed later in this chapter, are not repeated here.
Diagnostics
Local faults. These are viewable only using the module's Command Line Interface.
Controller faults. These can also be seen in the RX3i CPU Controller fault table, if the
ECM850 was connected to the RX3i CPU at the time the entry was added to the log.
I/O faults. These can also be seen in the RX3i CPU I/O Fault table, if the ECM850 was
connected to the RX3i CPU at the time the entry was added to the log.
