PROFINET system variables - PROFINET controller functionality
System variable Type - description
PNIO_SYSTEM_BF BOOL - Missing connection to a configured PROFINET device.
■
An error has occurred in the PROFINET network, i.e. no
connection could be established to at least one configured
PROFINET device.
■
This value is not set if the "Control BF" parameter on a
PROFINET device was set to FALSE. The PROFINET device
was thus removed from the connection monitoring.
PNIO_SYSTEM_SF BOOL - Diagnostic interrupt on a configured PROFINET device.
■
At least one PROFINET device reports a system error as a
diagnostic interrupt or maintenance alarm.
■
The error priority can be found in the variables
PNIO_DIAG_AVAILABLE, PNIO_MAINTENANCE_DEMANDED
and PNIO_MAINTENANCE_REQUIRED.
PNIO_MAINTENANCE_DEMANDED BOOL - maintenance demand
■
At least one PROFINET device reports a "maintenance
demand" - maintenance alarm with high priority when the con-
nection is active.
■
The PROFINET device can be identified by means of the
RALRM diagnostic block.
PNIO_MAINTENANCE_REQUIRED BOOL - maintenance required
■
At least one PROFINET device reports a "maintenance
required" - maintenance alarm with low priority when the con-
nection is active.
The PROFINET device can be identified by means of the RALRM
diagnostic block.
