Local Log Table of the PROFINET Controller

Since the embedded PROFINET and PNC001-Bxxx do not support the Command Line Interface (CLI), while the
older PNC001-Ax module does support CLI, the interactions become a little confusing. When reading this
section, keep in mind that CLI is supported by PNC001-Ax only. The Local Log Table is still present and behaves
the same in all respects, except for CLI interactions.
The Local Log table in the PROFINET Controller 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 Command Line Interface.
•
Controller faults. These are passed to the PACSystems CPU Controller Fault Table, provided the PROFINET
Controller was in communication with the CPU at the time the entry was added to the log.
•
I/O faults. These are passed to the PACSystems CPU I/O Fault Table, provided the PROFINET Controller
was in communication with the CPU at the time the entry was added to the log.
The PROFINET Controller maintains these entries in its Local Log table. Entries in the Local Log are preserved
across power-cycles. In the PNC001-Ax module, they may also be cleared using the CLI clear log command.
Clearing the CPU Fault Tables or restarting the PROFINET Controller does NOT clear the Local Log table.
If the Local Log table overflows, new entries overwrite the oldest entries, which are then lost. If that happens,
CLI indicates the number of entries that have been discarded. The count of discarded entries is reset to zero
whenever the Local Log table is cleared (applies to PNC001 module only).
The STATUS LED on the PNC001-Ax module 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 power-up, after the Local Log has been cleared, or after executing the clear
statLED command from CLI. When a subsequent fault occurs, the STATUS LED turns OFF to indicate that a new
fault has been logged.
