System variable Type - description
PNIO_CONFIG_STATUS_CFG_FAULT BOOL - target configuration error.
n The target configuration of the PROFINET controller was not
accepted due to a serious error.
n Please contact our support!
PNIO_FORCE_PRIMARY BOOL - This variable is used by function blocks for applicative
redundancy to specify the SRL role of the PROFINET controller.
PROFINET system variables - PROFINET device functionality
System variable Type - description
PND_S1_PLC_RUN BOOL - Status of the higher-level PROFINET controller.
n Information whether the higher-level PROFINET controller is
active.
n The value is TRUE if the higher-level PROFINET controller is in
RUN state and the program is being processed.
n The indication is only valid with existing PROFINET connection
(PND_S1_VALID_DATA_CYCLE).
PND_S1_VALID_DATA_CYCLE BOOL - the higher-level PROFINET controller has established the
connection.
n Information whether a connection exists and cyclic data is
exchanged between PROFINET controller and PROFINET
device and the last received frame contained valid data.
PND_S1_OUTPUT_STATUS_GOOD BOOL - IOP status of the higher-level PROFINET controller.
n Information whether the PROFINET device has received the
input process data (PND_S1_INPUTS) with the status "valid".
n The value is TRUE if the output data of the higher-level
PROFINET controller are valid (provider status).
PND_S1_INPUT_STATUS_GOOD BOOL - IOC status of the higher-level PROFINET controller.
PND_S1_DATA_LENGTH WORD - process data length which was configured for the
PROFINET device.
PND_S1_OUTPUTS PND_IO_512 - output process data
n Memory area for output process data that the PROFINET
device sends to the higher-level PROFINET controller.
PND_S1_INPUTS PND_IO_512 - input process data
n Memory area for input process data that the PROFINET device
receives from the higher-level PROFINET controller.
PND_IO_DRIVEN_BYPLC INT - Applicative system redundancy
n Number of the PROFINET controller currently connected to the
PROFINET device.
n Indication from which higher-level PROFINET controller the
data in the PROFINET device come from.
– 0: No PROFINET controller
– 1: PROFINET controller A
– 2: PROFINET controller B
