PROFINET system variables - PROFINET controller functionality
System variable Type - description
PNIO_SYSTEM_BF BOOL - Missing connection to a configured PROFINET device.
n An error has occurred in the PROFINET network, i.e. no con-
nection could be established to at least one configured
PROFINET device.
n 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.
n At least one PROFINET device reports a system error as a
diagnostic interrupt or maintenance alarm.
n The error priority can be found in the variables
PNIO_DIAG_AVAILABLE, PNIO_MAINTE-
NANCE_DEMANDED and PNIO_MAINTE-
NANCE_REQUIRED.
PNIO_MAINTENANCE_DEMANDED BOOL - maintenance demand
n At least one PROFINET device reports a "maintenance
demand" - maintenance alarm with high priority when the con-
nection is active.
n The PROFINET device can be identified by means of the
RALRM diagnostic block.
PNIO_MAINTENANCE_REQUIRED BOOL - maintenance required
n 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.
PNIO_FORCE_FAILSAFE BOOL - All PROFINET devices are prompted to set their configured
substitute values.
n The system variable can be written/set from the program if
required.
PNIO_CONFIG_STATUS WORD - configuration status of the PROFINET controller.
PNIO_CONFIG_STATUS_READY BOOL - PROFINET controller initialized.
n This variable is set if the PROFINET controller could be initial-
ized without errors.
n No target iCube Engineer configuration has been loaded yet.
PNIO_CONFIG_STATUS_ACTIVE BOOL - target configuration loaded.
n This variable is set when a target configuration was uploaded to
the PROFINET controller.
n In this state, the PROFINET controller tries to establish a con-
nection cyclically to all devices of the target configuration.
