Member Data Documentation

◆ amountInGSDML

uint16_t tagIoDataObject::amountInGSDML

Number of times this submodule appears in the GSDML, used for validation.

◆ api

uint32_t tagIoDataObject::api

Application Process Identifier scoping the module and submodule ident numbers.

◆ discardIOXS

bool tagIoDataObject::discardIOXS

True if the IOXS (IO provider/consumer status) byte should be suppressed during dissection.

◆ dstAddr

address tagIoDataObject::dstAddr

Network destination address of the consumer of this IO data object.

◆ f_crc_len

uint8_t tagIoDataObject::f_crc_len

Length in bytes of the PROFIsafe CRC appended to the safety data.

◆ f_crc_seed

bool tagIoDataObject::f_crc_seed

PROFIsafe CRC seed selection flag; false selects seed 0, true selects seed 1.

◆ f_dest_adr

uint16_t tagIoDataObject::f_dest_adr

PROFIsafe destination F-Address assigned to this safety device.

◆ f_par_crc1

uint16_t tagIoDataObject::f_par_crc1

PROFIsafe F-Parameter CRC1 integrity check value.

◆ f_src_adr

uint16_t tagIoDataObject::f_src_adr

PROFIsafe source F-Address assigned to the safety controller.

◆ fParameterIndexNr

uint32_t tagIoDataObject::fParameterIndexNr

F-Parameter index number used to locate PROFIsafe parameters for this object.

◆ frameOffset

uint16_t tagIoDataObject::frameOffset

Byte offset of this IO data object within the cyclic data frame.

◆ last_sb_cb

uint8_t tagIoDataObject::last_sb_cb

Most recently observed status or control byte value for this object, used for change detection.

◆ lastToggleBit

uint8_t tagIoDataObject::lastToggleBit

Last seen PROFIsafe toggle bit, used to detect retransmissions and sequence errors.

◆ length

uint16_t tagIoDataObject::length

Length in bytes of the IO data payload for this object.

◆ moduleIdentNr

uint32_t tagIoDataObject::moduleIdentNr

Module ident number as declared in the GSD/GSDML file.

◆ moduleNameStr

char* tagIoDataObject::moduleNameStr

Human-readable module name string sourced from the GSD/GSDML file.

◆ profisafeSupported

bool tagIoDataObject::profisafeSupported

True if this submodule has been identified as PROFIsafe-capable.

◆ slotNr

uint16_t tagIoDataObject::slotNr

Slot number of the module that owns this IO data object.

◆ srcAddr

address tagIoDataObject::srcAddr

Network source address of the device supplying this IO data object.

◆ subModuleIdentNr

uint32_t tagIoDataObject::subModuleIdentNr

Submodule ident number as declared in the GSD/GSDML file.

◆ subSlotNr

uint16_t tagIoDataObject::subSlotNr

Subslot number within the slot that owns this IO data object.

◆ tvb_slot

tvbuff_t* tagIoDataObject::tvb_slot

Tvbuff spanning the slot portion of the frame data, used for sub-dissection.

◆ tvb_subslot

tvbuff_t* tagIoDataObject::tvb_subslot

Tvbuff spanning the subslot portion of the frame data, used for sub-dissection.
