System variables and status information
107708_en_08 PHOENIX CONTACT 77 / 112
Table 8-12 lists the PROFINET system variables for the integrated PROFINET device func-
tionality.
PNIO_CONFIG_STATUS_ACTIVE BOOL This variable is set if the desired configuration for the PROF-
INET controller has been loaded.
In this state, the PROFINET controller attempts to cyclically
establish a connection to all devices in the desired configura-
tion (under the PROFINET icon).
PNIO_CONFIG_STATUS_CFG_FAULT BOOL The desired PROFINET controller configuration has not been
applied due to a serious error.
In this case, please contact Phoenix Contact.
PNIO_FORCE_PRIMARY BOOL Function blocks use this variable for applicative redundancy
to specify the SRL role of the PROFINET controller.

System variable Ty p e Description
PND_S1_PLC_RUN BOOL Status of the higher-level PROFINET controller
Information indicating whether the higher-level
PROFINET controller is active. The value is TRUE if the
higher-level 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 higher-level PROFINET controller has established
the connection.
Information indicating whether a connection exists and cy-
clic data is being exchanged between the PROFINET
controller and PROFINET device (AXC F 1152 or
AXC F 2152), and whether the last frame received con-
tained valid data.
PND_S1_OUTPUT_STATUS_GOOD BOOL IOP status of the higher-level PROFINET controller
Information indicating 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 higher-level PROFINET controller is valid (pro-
vider status).
PND_S1_INPUT_STATUS_GOOD BOOL IOC status of the higher-level PROFINET controller
PND_S1_DATA_LENGTH WORD Process data length that was configured for the
PROFINET device
PND_S1_OUTPUTS PND_IO_512 Output process data
Memory area for output process data that the PROFINET
device sends to the higher-level PROFINET controller
