Viewing and Clearing the Local Log Table
The only way to view and clear the data in the Local Log table of the PROFINET Controller is via the Command
Line Interface (CLI). As discussed above, CLI may only be used with the PNC001-Ax module.
•
Log data can be viewed via the CLI
log
or
show log
commands.
•
The Local Log table can only be cleared via the CLI
clear log
command, which requires Modify level access.
Clearing the PACSystems CPU Fault Tables or restarting the PROFINET Controller module does NOT clear
the Local Log table.
If the PROFINET Controller Local Log table overflows, new entries overwrite the oldest entries, which are lost. If
that happens, the CLI
log
or
show log
command indicates the number of entries that have been lost. The count
of lost entries is cleared whenever the Local Log table is cleared.
5.8.2.1
PROFINET Controller Local Log Display
Figure 95 shows a typical display using the log command. The
Loc
column identifies the device associated with
the log entry by its
Device Number
. Proficy Machine Edition assigns a unique
Device Number
for each Remote IO
Device. The
Device Number
000 identifies the PNC001 module itself.
