BACnetClientCreateObject (FB)

FUNCTION_BLOCK PUBLIC FINAL BACnetClientCreateObject EXTENDS BACnetClientBase

Common Behaviour Model conform (ETrigA) FB to execute a Create-Object-Reqeust in the BACnet-Network. If execution completed successfully and xDone is TRUE,CreateObjectID holds mthe ID of the created object. If the request fails, firstFailed holds the index of the first property, due to which reason the creation failed.

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.

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

objectSpecifier

CmpBACnet.IEC_BACNET_OBJECT_SPECIFIER

This parameter contains information about the type of object that is to be created. The datatype is a choice between an object type and an object identifier. If the object type choice is used, the specified object type shall become the value of the Object_Type property of the newly created object and the responding BACnet-user shall select an object identifier. If the object identifier choice is used, an object with this particular object identifier shall be created.

bValuesPresent

BOOL

TRUE

If set to True the list of initial values is valid.

nValuesCount

CmpBACnet.IEC_BACNET_UNSIGNED

Number of entries in the list of initial values.

pValues

POINTER TO CmpBACnet.IEC_BACNET_PROPERTY_VALUE

This parameter contains a list of BACnetPropertyValues that will be used to initialize the values of the specified properties of the newly created object.

Output

createdObjectID

CmpBACnet.IEC_BACNET_OBJECT_ID

If the BACnet-Request succeeded (xDone is TRUE and no error occured (xError is FALSE)), this variable holds the object ID of the created object.

firstFailed

CmpBACnet.IEC_BACNET_UNSIGNED

If the BACnet-Request failed, this variable shall hold the first property, for which the creation of the object failed.
