BACnetServerConfEventNotification (FB)

FUNCTION_BLOCK PUBLIC FINAL BACnetServerConfEventNotification EXTENDS BACnetClientBase

Common Behaviour Model conform (ETrigA) FB to send a ConfirmedEventNotification-Request in the BACnet-Network. If execution completed successfully and xDone is TRUE, the request was successful. In any other case eStatus and errorResult may hold additional information of what 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.

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

initObject

CmpBACnet.IEC_BACNET_OBJECT_ID

This parameter, of type BACnetObjectIdentifier, specifies the Object_Identifier of the object that is initiating the notification.

messageText

CmpBACnet.IEC_BACNET_STRING

This optional parameter, of type CharacterString, contains a string of printable characters. This parameter may be used to transport a message to be logged or displayed, which pertains to the occurrence of the event. Set string type to BACNET_STRING_NONE for no message text to be sent.

pMandatoryParams

A pointer to the mandatory service parameters.

pConditionalParams

POINTER TO CmpBACnet.IEC_BACNET_EN_CONDITIONAL

A pointer to the conditional service parameters.
