BACnetClientDeleteObject (FB)

FUNCTION_BLOCK PUBLIC FINAL BACnetClientDeleteObject EXTENDS BACnetClientBase

Common Behaviour Model conform (ETrigA) FB to execute a Delete-Object-Reqeust in the BACnet-Network. If execution completed successfully and xDone is TRUE no additional variable gets its contents updated, but it is indicated, that the deletion succeeded.

Input

dwTargetDeviceNumber

DWORD

The device number of the targeted device in the BACnet- Network.

BACnetClientBase

pTargetDeviceAddress

POINTER TO CmpBACnet.IEC_BACNET_ADDRESS

0

Optional: The device address of the targeted device in the BACnet-Network. If an adress is given the given device number is ignored.

BACnetClientBase

pAPDUParams

POINTER TO CmpBACnet.IEC_BACNET_APDU_PROPERTIES

0

A pointer to the structure which contains a set of APDU properties to control the timing and size of transmitted frames for this request. It temporarily overwrites the global APDU settings made in the source device from which this request is sent and which parameters would control this request if this pointer is NULL.

BACnetClientBase

Output

eStatus

CmpBACnet.IEC_BACNET_STATUS

CmpBACnet.IEC_BACNET_STATUS.BACNET_STATUS_OK

If an error occured, the error state.

BACnetClientBase

errorResult

CmpBACnet.IEC_BACNET_ERROR

STRUCT(tag := CmpBACnet.IEC_BACNET_FAILURE_TYPE._FAILURE_MAX_SIZE)

If an error occured (this means eStatus <> BACNET_STATUS_OK), whereas the sent BACnet-Request was answered with an specific error information, the latter is contained in this structure.

BACnetClientBase

iState

DINT

0
The State in which the FB is during execution:

  • 0: No execution, resetted state

  • 1: Searching for the Target-Device and a valid address for it

  • 2: Sending the BACnet-Request into the network

  • 3: Waiting for the answer (if there is one) to the BACnet-Request made in 2

  • 4: Finishing the call, setting of the output variables

BACnetClientBase

Input

objType

CmpBACnet.IEC_BACNET_OBJECT_TYPE

The type of the object to be deleted.

objInst

CmpBACnet.IEC_BACNET_DWORD

The instance number of the object to be deleted.

pValueSrc

POINTER TO CmpBACnet.IEC_BACNET_AUDIT_VALUE_SOURCE

0

Optional: A pointer to a data structure which contains the value source information for generating an logged and/or reported audit notification for this initiated request. If generating an logged and/or reported audit notification for this request is not intended, pValueSrc can be set to 0.
