BACnetClientLifeSafetyOperation (FB)

FUNCTION_BLOCK PUBLIC FINAL BACnetClientLifeSafetyOperation EXTENDS BACnetClientBase

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

eStatus

CmpBACnet.IEC_BACNET_STATUS

CmpBACnet.IEC_BACNET_STATUS.BACNET_STATUS_OK

If an error occured, the error state.

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

fSafetyObjectIdPresent

CmpBACnet.IEC_BACNET_BOOLEAN

If set to true the objectID parameter is valid and present.

processID

CmpBACnet.IEC_BACNET_UNSIGNED

The processID attribute is the numeric identifier of the Process within the client which shall receive the notifications.

requestingSource

CmpBACnet.IEC_BACNET_STRING

This attribute specifies the identity of the human operator that initiates this service request.

eRequest

CmpBACnet.IEC_BACNET_LIFE_SAFETY_OPERATION

This attribute specifies the requested operation (which may take on one of the standard values: NONE, SILENCE, SILENCE_AUDIBLE, SILENCE_VISUAL, RESET, RESET_ALARM, RESET_FAULT).

objectID

CmpBACnet.IEC_BACNET_OBJECT_ID

The object ID attribute is optional. If it is omitted the request is interpreted as an operation on all applicable objects within the receiving device. The mask attribute indicates if the object ID is present.
