ReceiveSMS (FB)¶

FUNCTION_BLOCK ReceiveSMS EXTENDS CBM.ETrigTo

By use of this function block, the oldest short message from the device is displayed.
Just when the message is deleted, the next one is shown.
After starting this function block, it will try to allocate the modem.
When it is free a lock is set and therefore reserved for the currently function block.
After a reset (falling edge on “xExecute”) the lock is released.

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
Inout	`ModemFB`	Modem	The modem function block
Output	`eError`	ERROR	error code
	`VisuResult`	VISU_RESULT	This output is needed for the visualization.
	`smsRecv`	SMS_RECV	This structure includes the received short message
