BACnetServerConfCOVNotification (FB)

FUNCTION_BLOCK PUBLIC FINAL BACnetServerConfCOVNotification EXTENDS BACnetClientBase

Common Behaviour Model conform (ETrigA) FB to send a ConfirmedCOVNotification-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

processID

CmpBACnet.IEC_BACNET_UNSIGNED

This parameter, of type Unsigned, contains a numeric “handle” meaningful to the subscriber. This handle shall be used to identify the process within the COV client that should receive the notification.

monitoredObjectID

CmpBACnet.IEC_BACNET_OBJECT_ID

This parameter, of type BACnetObjectIdentifier, contains the Object_Identifier of the object that has changed.

timeRemaining

CmpBACnet.IEC_BACNET_UNSIGNED

This parameter, of type Unsigned, contains the remaining lifetime of the subscription in seconds. A value of zero shall indicate an indefinite lifetime without automatic cancellation.

listOfValues

POINTER TO CmpBACnet.IEC_BACNET_PROPERTY_VALUE

This parameter contains a list of one or more property values whose contents depends on the type of object being monitored.

nValueCount

CmpBACnet.IEC_BACNET_ELEMENT_COUNT

The count of values in the list of value.
