The PROFINET Controller
’s Local Log Table
The PNC
’s local log table contains entries indicating events and errors. There can be three types of
entries in the local log table:
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 PNC
module 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 PNC module was
connected to the RX3i CPU at the time the entry was added to the log.
The PNC 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 PNC module does NOT clear the
local log table.
If the PNC
module’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 PNC module
’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.
