BACnetClientWritePropertyMultiple (FB)

FUNCTION_BLOCK PUBLIC FINAL BACnetClientWritePropertyMultiple EXTENDS BACnetClientBase

Common Behaviour Model conform (ETrigA) FB to execute a Write-Property-Multiple-Request in the BACnet-Network. If execution completed successfully and xDone is TRUE, the Write-Multiple-Request was successful. In any other case eStatus and errorResult may hold additional information of what failed, whereas firstFailed may hold the index of the first property which could not be written.

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

nListCount

CmpBACnet.IEC_BACNET_UNSIGNED

Number of Write-Property-Lists given in the POINTER writeSpec.

writeSpec

POINTER TO CmpBACnet.IEC_BACNET_WRITE_LIST

Write-Property-Lists identifying the properties to be written.

Output

firstFailed

CmpBACnet.IEC_BACNET_DEV_OBJ_PROP_REFERENCE

If the Write-Property-Multiple-Request failed, this variable holds the property which first failed to be written.
