4.5 PROFINET register
The PC Worx Express software does not support this function.
Table 4-4 PROFINET system variables (PROFINET device function)
System variable Type Meaning
PND_S1_PLC_RUN BOOL Status of the higher-level controller/PROFINET controller
Information indicating whether the higher-level controller
is active. The value is TRUE if the higher-level controller is
in the RUN state (program). The display only applies
when there is an existing PROFINET connection
(PND_S1_VALID_DATA_CYCLE).
PND_S1_VALID_DATA_CYCLE BOOL The higher-level controller/higher-level PROFINET con-
troller has established the connection.
Information indicating whether a connection exists and
cyclic data is being exchanged between the PROFINET
controller and PROFINET device and whether the last
frame received contained valid data.
PND_S1_OUTPUT_STATUS_GOOD BOOL IOP status of the higher-level controller/higher-level PRO-
FINET controller
Information indicating whether the IN process data of the
PROFINET device (PND_S1_INPUTS) was received by
the PROFINET device with “valid” status. The value is
TRUE if the output data of the higher-level controller is
valid (provider status).
PND_S1_DATA_LENGTH WORD Process data length that was configured for the PROFI-
NET device.
PND_S1_OUTPUTS PND_IO_256 OUT process data
Memory area for OUT process data that the PROFINET
device sends to the higher-level controller/higher-level
PROFINET controller.
PND_S1_INPUTS PND_IO_256 IN process data
Memory area for IN process data that the PROFINET de-
vice receives from the higher-level controller/higher-level
PROFINET controller.
PND_IO_DRIVEN_BY_PLC INT Applicative system redundancy
Specifies from which higher-level PROFINET controller
the data in the PROFINET device originates (refer to
Figure 2-5 on page 16)
0: No PROFINET controller
1: Controller A
2: Controller B
