UDP_SendBuffer (FB)¶

FUNCTION_BLOCK UDP_SendBuffer EXTENDS CBM.ETrigTo

Like UDP_Send this function block serves to sent data.

Instead of a pointer to the data, this function block expects a handle of the buffer containing the data to be written. The buffer is passed on and not copied like at UDP_Send.

The time out value has no effect at this function block.

InOut:

Scope	Name	Type	Comment	Inherited from
Input	`xExecute`	`BOOL`	Rising edge: Action starts Falling edge: Resets outputs If a falling edge occurs before the function block has completed its action, the outputs operate in the usual manner and are only reset if either the action is completed or in the event of an error. In this case, the corresponding output values (`xDone`, `xError`) are present at the outputs for exactly one cycle.	ETrigTo
Input	`udiTimeOut`	`UDINT`	Defines the time (µs) after which an FB (e.g. requiring an external acknowledgement) aborts operation due to a timeout with error message.	ETrigTo
Output	`xDone`	`BOOL`	`TRUE`: Action successfully completed	ETrigTo
	`xBusy`	`BOOL`	`TRUE`: Function block active	ETrigTo
	`xError`	`BOOL`	`TRUE`: Error occurred, function block aborts action `FALSE`: No error	ETrigTo
Input	`hPeer`	`CAA.HANDLE`
	`ipAddr`	IP_ADDR
	`uiPort`	`UINT`
	`hBuffer`	`CAA.HANDLE`
Output	`eError`	ERROR
