Description
No connection to a configured PROFINET device
An error has occurred in the PROFINET network, i.e., a con-
nection could not be established to at least one configured
PROFINET device. This value is not set if the "Control BF" pa-
rameter was set to FALSE for a PROFINET device. The
PROFINET device has therefore been excluded from con-
nection monitoring.
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_MAINTE-
NANCE_REQUIRED variables.
Maintenance demand
At least one PROFINET device is indicating the "maintenance
demand" alarm (high-priority maintenance alarm) with an ac-
tive connection. The PROFINET device can be identified
using the RALRM diagnostic block.
Maintenance required
At least one PROFINET device is indicating the "maintenance
requirement" alarm (low-priority maintenance alarm) with an
active connection. The PROFINET device can be identified
using the RALRM diagnostic block.
All PROFINET devices are prompted to set their configured
substitute values.
If required, the system variable can be written/set from the
program.
Configuration status of the PROFINET controller
This variable is set if the PROFINET controller has been ini-
tialized correctly. No desired configuration has been loaded
by PLCnext Engineer yet.
