BACnetClientAddListElement (FB)

FUNCTION_BLOCK PUBLIC FINAL BACnetClientAddListElement EXTENDS BACnetClientBase

Common Behaviour Model conform (ETrigA) FB to execute a Add-List-Element-Request in the BACnet-Network. If execution completed successfully and xDone is TRUE, the Add-List-Element-Request was successful. In any other case eStatus and errorResult may hold additional information of what failed and firstFailed holds the index of the first element, which failed to be added.

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

propID

CmpBACnet.IEC_BACNET_PROPERTY_ID

The property ID of the property of the object under the targeted device to add a list element to.

nIndex

CmpBACnet.IEC_BACNET_SIGNED

The Index of the element in the property, where the elements of property Contents shall be added.

elements

CmpBACnet.IEC_BACNET_PROPERTY_CONTENTS

The elements to be written into the property (compare elements.nElements).

Output

firstFailed

CmpBACnet.IEC_BACNET_UNSIGNED

If the Add-List-Element-Request failed, this variable holds the index of the first element, which failed to be added.
