BACnetClientBase (FB)¶

FUNCTION_BLOCK PUBLIC BACnetClientBase EXTENDS CBML.ETrigATo IMPLEMENTS IBACnetClient, IBACnetClientInternal

Base class for all BACnet-Client-FBs. It hold both source Address and target Address for the BACnet-Client-FBs. The source address gets automatically set to the device of the parent BACnet-Server-FB (in the device tree BACnet-Clients are always childs of BACnet-Servers). The target address has to be set (TargetDeviceAddress-, TargetDeviceNumber Property) before any call to the other functions of the BACnet-Client-FBs.

InOut:

Scope	Name	Type	Initial	Comment	Inherited from
Input	`xExecute`	`BOOL`		Rising edge: Starts defined operation `FALSE`: Resets the defined operation after ready condition was reached	ETrigATo
	`xAbort`	`BOOL`		`TRUE`: Aborts the operation	ETrigATo
	`udiTimeOut`	`UDINT`		Max. operating time for executing [µs], 0: No operating time limit	ETrigATo
Output	`xDone`	`BOOL`		`TRUE`: Ready condition reached	ETrigATo
	`xBusy`	`BOOL`		`TRUE`: Operation is running	ETrigATo
	`xError`	`BOOL`		`TRUE`: Error condition reached	ETrigATo
	`xAborted`	`BOOL`		`TRUE`: Abort condition reached	ETrigATo
Input	`dwTargetDeviceNumber`	`DWORD`		The device number of the targeted device in the BACnet- Network.
	`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.
	`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.
Output	`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.
	`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
