PROFINET Alarm Action
If a PROFINET I/O Alarm occurs, the action is Diagnostic (the action type is not configurable).
When a fault in this group is processed, the CPU sets the following status bits: #ANY_FLT,
#IO_FLT, #IO_PRES, and #PNIO_ALARM (%SA30).
The #PNIO_ALARM status bit is cleared whenever the I/O Fault Table is cleared.

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.
