UDP_Send (FB) ¶ FUNCTION_BLOCK UDP_Send EXTENDS CBM.ETrigTo This function block serves to sent data. The content of the memory area indicated by pointer pData contains the data to be written. szSize defines the number of bytes to be written. When xDone is set to TRUE the data was written successfully. 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 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 szSize CAA.SIZE pData CAA.PVOID Output eError ERROR

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 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
