4.1.3 Status register of a PROFINET controller
(ILC 330 PN / ILC 350 PN)
Table 4-2 Variables of the status register for a PROFINET controller
System variable Type Meaning
PNIO_SYSTEM_BF BOOL No connection to a configured PROFINET device
An error has occurred in the PROFINET network, i.e., a
connection could not be established to at least one
configured device. This value is not set if the “Control BF”
parameter is set to FALSE for a device. This device has
therefore been excluded from connection monitoring.
PNIO_SYSTEM_SF BOOL Diagnostic alarm on a configured PROFINET device
At least one PROFINET device is indicating a system error
(diagnostic alarm or maintenance alarm). The error priority
can be determined from the PNIO_DIAG_AVAILABLE,
PNIO_MAINTENANCE_DEMANDED, and
PNIO_MAINTENANCE_REQUIRED variables.
PNIO_DIAG_AVAILABLE BOOL Diagnostics available
At least one PROFINET device is indicating a diagnostic
alarm for an active connection. The corresponding
device(s) can be identified using the RALRM diagnostic
block or by requesting the PN_DA_NO_DIAG diagnostic
status byte of each device.
The application must decide, for example, whether outputs
of the other PROFINET devices in the network may
continue to be operated.
PNIO_MAINTENANCE_DEMANDED BOOL Maintenance demanded – maintenance demand
At least one PROFINET device is indicating the
“maintenance demand” alarm (high-priority maintenance
alarm) for the active connection. The device can be
identified using the RALRM diagnostic block.
PNIO_MAINTENANCE_REQUIRED BOOL Maintenance required – maintenance requirement
At least one PROFINET device is indicating the
“maintenance requirement” alarm (low-priority
maintenance alarm) for the active connection. The device
can be identified using the RALRM diagnostic block.
PNIO_CONFIG_STATUS WORD Configuration status of the PROFINET controller
PNIO_CONFIG_STATUS_READY BOOL The variable is set if the PROFINET controller has been
initialized correctly. No desired configuration has been
loaded by PC Worx yet.
