Table 8-4 lists the PROFINET system variables for the integrated PROFINET device func-
tions.
Table 8-4 PROFINET system variables (PROFINET device functions)
System variable Type Description
PND_S1_PLC_RUN BOOL Status of the superordinate PROFINET controller
Information on whether the superordinate PROFINET
controller is active. The value is TRUE if the superordinate
PROFINET controller is in the RUN state (program is
being processed). The display only applies when there is
an existing PROFINET connection
(PND_S1_VALID_DATA_CYCLE).
PND_S1_VALID_DATA_CYCLE BOOL The superordinate PROFINET controller has established
the connection
Information on whether a connection exists and cyclic
data is being exchanged between the PROFINET control-
ler and PROFINET device (AXC F 1050) and whether the
last frame received contained valid data.
PND_S1_OUTPUT_STATUS_GOOD BOOL IOP status of the superordinate PROFINET controller
Information on whether the input process data
(PND_S1_INPUTS) was received by the PROFINET de-
vice with the “valid” status. The value is TRUE if the output
data of the superordinate PROFINET controller is valid
(provider status).
PND_S1_INPUT_STATUS_GOOD BOOL IOC status of the superordinate PROFINET controller
PND_S1_DATA_LENGTH WORD Process data length that was configured for the
PROFINET device
PND_S1_OUTPUTS PND_IO_256 Output process data
Memory area for output process data that the PROFINET
device sends to the superordinate PROFINET controller
PND_S1_INPUTS PND_IO_256 Input process data
Memory area for input process data that the PROFINET
device receives from the superordinate PROFINET con-
troller
PND_IO_DRIVEN_BY_PLC INT Applicative system redundancy
Specifies the superordinate PROFINET controller from
which the data in the PROFINET device originates.
